The NB slide way NV type comprises of precisely ground rails and R-retainers with built-in STUDROLLERs and precision rollers. The rails have been optimally designed so that the STUDROLLERs move smoothly, and the STUDROLLERs and precision rollers incorporated in the R-retainers enable slip-free operation between the raceway surface and the rollers resulting in motion with minimal frictional resistance.SV and SVW types consist of precision ground rails and precision caged-rollers. Since caged-rollers do not recirculate, there is only a minimum frictional resistance fluctuation. Also, there is a minimum difference between the static and dynamic frictional resistances.
The STUDROLLER system is based on a new concept to provide complete prevention of roller cage slippage during operation. This system permits usage in all orientations and positions.
The NB slide way is a non-recirculating linear motion bearing utilizing precision rollers. It is used primarily in optical and measurement equipment where high precision movement is required.
STRUCTURE AND ADVANTAGES
※To the NV type, fastening plates are attached for the purpose of maintaining the center position of the R-retainer before assembly. Please see Installation Procedure on page G-7 and remove the fastening plates before use.

TYPES
The NV slide way consists of a set of four rails, two R-retainers, and eight end pieces. It permits flexible design of the table which will best suit your application. The NVS-RNS type has all stainless steel components, which is suitable for anti-corrosion, high temperature and vacuum requirements.

P.G-12
Suitable for Minute MotionBecause the frictional resistance is extremely small and there is only little difference between the static and dynamic frictional resistances, the NB slide way is well suited for minute motion, resulting in highly accurate linear movement.
Low-Speed StabilitySince the frictional resistance fluctuation is small even under low-load conditions, stable motion is obtained at from low to high speeds.
High Rigidity and High Load CapacityCompared to the ball elements, the rollers provide a larger contact area and less elastic deformation, thus the NB slide way has high rigidity and high load capacity. With new NV rail design, the roller contact area is increased by 30 to 58% (Figure G-2). The number of effective rollers is increased by narrowing the roller pitch. Thus, the NV type has the load rating that is 1.3 to 2.5 times that of the SV type.
Low NoiseThe slide way never produces recirculation noise nor roller-contact noise due to a use of roller cage, resulting in quiet motion.
All Stainless Steel Type AvailableThe anti-corrosion SVS/SVWS/NVS-RNS slide ways have all stainless steel components, making them ideal for use in clean room applications.Figure G-2 Roller Contact Profile

The SV slide way consists of a set of four rails, two R type roller cages, which have precision rollers in a cross arrangement, and eight end pieces. The all stainless steel option makes it suitable for use in corrosive environments.
The SVW slide way consists of two SV-type rails, one W type rail, two R type roller cages, and eight end pieces. The use of a W-type rail serves for a compact design. The SVWS type is also available with all stainless steel components.

STROKE
Please contact NB for a non-standard stroke length for the NV type. When the stroke of SV type or SVW type is changed, the stroke length must be determined and the load rating should be re-estimated as follows.
Stroke of SV type, SVW typeWhen the slide way moves along the rail, the cage moves half the distance traveled by the slide way in the same direction. Therefore, although the work may be fixed on the table, the distance between the load center and the cage center will change. To achieve stable accuracy, determine the stroke and the length of the rail as follows.

LUBRICATION AND DUST PREVENTION
Lubrication The slide way is pre-lubricated with lithium soap-based grease No.00 prior to shipment for immediate use. Make sure to relubricate with a similar type of grease periodically according to the operating conditions. NB also provides low dust generation grease. Please refer to page Eng-40 for details.
Dust Prevention Foreign particles or dust in the slide way affects the motion accuracy and shortens the life time. In a harsh environment please provide side covers for dust prevention. (refer to Figure G-9)

SHAPE OF MOUNTING SURFACE
Slide way NV and SV types are generally mounted by contacting the reference surface of the rail to the shoulder provided on the mounting surface. For the shoulder shape, provide relief at the corner as shown in Figure G-13 so that it does not interfere with the reference corner of the rail.If it is nessaray to mount NV or SV types without relief, then it can be used with rounded corners as shown in Figure G-14. Table G-3 shows the corner radius of the mounting surface.

USE AND HANDLING PRECAUTIONS
Careful HandlingDropping the slide way causes the rolling elements to make dents in the raceway surface. This will prevent smooth motion and will also affect accuracy. Be sure to handle the product with care. The NV type is packaged as a set of rails and R-retainers. Do not separate or disassemble until assembly/installation is completed. Precision is not guaranteed if disassembled.
Fastening PlatesFor the NV type, fastening plates are attached at both end faces of the rails to maintain the R-retainer center position prior to assembly. The fastening plates are not required after the NV type is mounted to a table and bed, however, when removal of the NV type is necessary such as when it will be reassembled, be sure to return the R-retainer to the proper center position, secure the fastening plates with the end pieces, and then remove the NV type.
Specified Allowable StrokeFor the NV type, exceeding the specified stroke (over-stroke) shall cause the raceway surface of the rail to be damaged and the performance of the STUDROLLER to drastically deteriorate. Be sure to provide external mechanical stoppers.
AdjustmentUsing the product with insufficient accuracy of the mounting surface or before adjusting the preload will cause the motion accuracy of the product to drop and will have a negative influence upon product life and accuracy. Make sure to assemble, install, and adjust the product with care.
Caution against Excess PreloadIt is essential to give preload on the Slide Way products in order to assure rigidity and accuracy.However, excess preload causes damage on the raceways and roller cages/R-retainers.On installation, please follow the installation procedure and recommended torque on page G-9.
Operating TemperatureThe NV type uses resin parts. Please use the product in environments that are lower than 80℃ .
Use as a SetThe accuracy of the rails has been matched within each set. Note that the accuracy will be affected when the rails of different sets are combined.
Allowable LoadThe allowable load is a load under which the sum of elastic deformations of the rolling element and the raceway in the contact area subject to the maximum contact stress is small enough to guarantee smooth rolling movement. When very smooth and highly accurate linear motion is required, make sure to use the product within the allowable load.
Cage SlippageFor the SV/SVW type, the cage can slip under high-speed motion, vertical application, unbalanced-loading, and vibrating conditions. It is advised that the stroke be set with sufficient margin and an excessive preload should be avoided. It is also recommended that the rails be cycled to perform the maximum stroke several times, so that the cage returns to its center position.
End PiecesEnd pieces are attached to each end of the slide way to prevent removal of the cage. Do not use them as a mechanical stopper.
Knock Pin HoleWhen using SVW type knock pin holes to attach a slide way, please do the hole-machining on the mounting surface after attaching the W type rail. After machining, remove the chips completely and wash as required.
SPECIAL MOUNTING SCREW BT TYPE
In case of mounting slide way by screws from the counterbore side, threaded holes become the pilot holes. Thus, pilot hole's clearance will be less than a standard clearance hole for a screw. NB offers reduced shoulder screws for mounting SlideWay from bottom when larger screw clearance is required due to preload adjustment or inaccuracy of mating threaded holes. This special mounting screw made of alloy steel is stocked, and custom stainless steel version is available as a special order. Please contact NB for details.

NB can machine tables to meet special requirements, including tables with a micrometer head and tables for projectors. Please contact NB for details.
The life of an NB slide table is calculated using the following equations.
Rated Life Life Time
Lh: life time (hr) ℓS: stroke length(m) n1: number of cycles per minute(cpm)
L: rated life(km) fT: temperature coefficient fW: applied load coefficientC: basic dynamic load rating(N) P: applied load(N)※Please refer to page Eng-5 for the coefficients.

Careful HandlingDropping the slide table causes the rolling elements to make dents in the raceway surface. This will prevent smooth motion and will also affect accuracy. Be sure to handle the product with care.
Dust PreventionDust and foreign particles affect the accuracy and lifetime of a slide table. A slide table used in a harsh environment should be protected with a cover.
LubricationThe slide table is prelubricated with lithium soap based grease No.00 prior to shipment for immediate use. Make sure to relubricate with a similar type of grease periodically depending on the operating conditions.
Cage SlippageFor the SVT/SYT type, the cage can slip under high-speed motion, vertical application, unbalanced-loading, and vibrating conditions. It is advised
that the motion speed be kept under 0.5m/s under general operating conditions. It is also recommended that the rails be cycled to perform the maximum stroke several times, so that the cage returns to its central position.
Adjustment/Installation Screw The NB slide table is adjusted to achieve optimum accuracy and preload. The adjustment screw and rail installation screws should be kept untouched.
Allowable LoadThe allowable load is a load under which the sum of elastic deformations of the rolling element and the raceway in the contact area subject to the maximum contact stress is small enough to guarantee smooth rolling movement. When very smooth and highly accurate linear motion is required, make sure to use the product within the allowable load.

The load rating of the slide table NVT type and NYT type differs depending on the direction of the load.
※There may be a difference depending on the size. Please contact NB for details. Consideration has been given to holes for STUDROLLERs in the raceway surface in calculation of load ratings.

MINIATURE SLIDEThe NB miniature slide SYBS type is a limited stroke table with the most compact envelope dimensions, featuring two ball raceway grooves. The SYBS type utilizes balls as the rolling elements. The ultra compact design contributes greatly to the creation of smaller and lighter industrial machinery and equipment of all types.
STRUCTURE AND ADVANTAGES
The NB miniature slide incorporates a unique integrated ball cage between the table and bed. All components have been produced with high precision machining.
Ultra Compact DesignThe table height of the SYBS type is 3.2~8mm and the width is 6~17mm. This compact size when compared with conventional slide tables helps to realize the miniaturization of machinery and equipment.
Low Friction ・ Low NoiseSince the rolling ball elements do not recirculate, the frictional resistance will not vary significantly resulting in smooth, high precision operation. Additionally, the
ball cage greatly reduces the contact noise of the rolling elements bringing about a low-noise operation.
High AccuracyThe ball raceway grooves of each of the bed and table are processed through simultaneous precision machining resulting in minimal processing errors, and bringing about extremely smooth, precision linear movement.
Stainless Steel StructureThe SYBS type is made of all stainless steel components. This allows for use in corrosive or high temperature applications. The SYBS is a perfect component for vacuum or clean room environments.

Mounting Example and Mounting ScrewAll the mounting holes are for SYBS 6,8,12 fully through-hole. Mount SYBS 6,8,12 as illustrated in Figure G-30 after considering the size of mounting screw, the maximum penetration depth, and the height of the bed. Make certain that the mounting screws do not interfere with the ball cage; otherwise, the accuracy and travel life will be affected adversely. Special screws for SYBS type are available from NB. Please refer to Table G-13 for dimensions of mounting screws.

USE AND HANDLING PRECAUTIONS
PreloadThe SYBS miniature slide is provided with a slightly positive clearance type only.
End PieceOn both ends of the SYBS miniature slide bed section, screws are attached to prevent the ball cage from escaping. Please note that the screws are designed only to prevent the ball cage from escaping and are not intended for the use as a mechanical stopper. The ball cage may become deformed on contact with the stopper and this will result in a negative affect of the accuracy and travel life.
LubricationNB miniature slide SYBS type is supplied with an initial application of lithium soap grease No.0 and therefore is ready for immediate use. Make sure to relubricate with a similar type of grease periodically according to the operating conditions. For use in clean rooms or vacuum environments, miniature slide tables without grease or with customer specified grease are available. NB also provides low
dust generation grease. Please refer to page Eng-41 for details.
Cage SlippageFor the SYBS type, the cage can slip under high-speed motion, vertical application, unbalanced-loading, and vibrating conditions. It is advised that the motion speed be kept under 0.5m/s under general operating conditions. It is also recommended that the table be cycled to perform the maximum stroke several times, so that the cage returns to its center position.
Allowable LoadThe allowable load is a load under which the sum of elastic deformation of the rolling element and the raceway in the contact area subject to the maximum contact stress is small enough to guarantee smooth rolling movement. When very smooth and highly accurate liner motion is required, make sure to use the product within the allowable load values.

MOUNTING
Mounting Surface ProfileIn most general installations, the miniature slide is mounted by pushing the reference surface of the bed and table against a shoulder that is set up on the mounting surface. Machined undercuts should be used in the corners of the shoulder (as illustrated in Figure G-27) so that the corners will not interfere with the reference surfaces of the bed and table. Table G-10 lists the recommended shoulder heights of the mounting reference surfaces.When installing the miniature slide table without providing machined undercuts, the corner radius should be realigned as illustrated in Figure G-28. Table G-11 lists the values of the corner radius of the mounting surface.

NB mark
The reference surfaces are located on the opposite side of the NB mark. There are inner reference surface and outer reference surface in one set of RV.
The NB gonio way is a curved cross roller slide way. It is a curved motion bearing utilizing low-friction, non-recirculating precision rollers. It is used when there is a need to change the gradient or obtain an accurate gradient angle without changing the center of rotation in high-precision optical and measurement equipment.
STRUCTURE AND ADVANTAGES
Low Frictional Resistance and Minute MotionThe precision grinding and curved roller cage allow for extremely low frictional resistance. The negligible difference between static and dynamic frictions allows the gonio way to follow minute movements accurately, realizing curved movement of high accuracy.
Low NoiseSince NB gonio way employs a non-recirculating design, there is no noise from the circulating area. In addition, the curved roller cage realizes quiet operation without contact noise between the rolling elements.
High Rigidity and High Load CapacityThe rollers provide a larger contact area and less
elastic deformation compared to the ball elements. Additionally, since the rollers do not recirculate, the effective number of rotating elements is larger, resulting in high rigidity and high load capacity.
Flat Installation SurfaceThe flat installation surfaces of the RVF type do not require complicated machining of tables and beds when installing the product. As a result, machining costs can be reduced greatly.
Same Rotation CenterThe curved V-grooves, which are finished with a precise grinding process, provide an accurate center of rotation. Furthermore, the products are composed to provide identical rotation centers when products of each size are installed to two axes.(refer to Table G-19.)
GONIO WAY
The NB gonio way RVF type consists of curved tracking bases with precisely ground V-grooves and flat installation surfaces, as well as curved roller cages. The NB gonio way RV type consists of curved rails with precisely machined V-grooves and curved roller cages. Precision rollers are employed as the rolling elements, since the rolling elements do not recirculate, the frictional resistance will not vary significantly, providing curved movement with extremely low frictional resistance.

Setting four curved tracking bases in parallel position
( 5 ) Move the table to the maximum stroke ends of both sides and adjust the setting so that the curved roller cage is positioned at the center of the curved tracking base.
( 6 ) Move the table to the center position and tighten the adjustment screws with ※slightly strong torque by using a torque wrench. (Figure G-39d)
※"Slightly strong torque" here means slightly stronger than the torque at which the oscillation of the dial indicator is stabilized at the minimum value when the table is moved right and left, or when pressure is applied to the rolling direction while the dial indicator is attached to the side face (reference side) of the table. (Figure G-39i)
( 7 ) Move the table to the maximum stroke end of one side and tighten the adjustment screws on the curved roller cage with the same torque as in step (6). (Figure G-39e)
( 8 ) Move the table to the maximum stroke end of the other side and tighten the adjustment screws with a torque wrench by repeating the procedure above. (Figure G-39f)
Securing the curved tracking bases( 9 ) Mount an edge reference plate between the
reference edge of the a-curved tracking base and end piece, press it against the reference edge of the bed, and then tighten only the rail mounting bolts in the middle. (Figure G-39g)
(10) Repeat the procedure above to mount an edge reference plate between the reference edge of the b-curved tracking base and the end piece. Press it against the reference edge of the bed, and then tighten only the rail mounting bolts in the middle. (Figure G-39h) In order to maintain parallelism of curved tracking bases, do not cycle the table during this process and make sure that there is no clearance between the edge of the table and the edge reference plate.
(11) Secure the rest of the rail mounting bolts on the curved roller cage one by one by moving the table as instructed in steps(7)and(8).
Adjusting the preload(12) Move the table to the right and left with the
test indicator attached to the side face of the table (reference side). Or, apply pressure in the rolling direction and confirm that the oscillation of the indicator is stabilized at the minimum level. (Figure G-39i)
(13) Return the rail mounting bolts on the b-curved tracking base at the adjustment screw side to the temporary setting.
(14) Return the table to the center position, slightly loosen the adjustment screws in the middle, and then gradually loosen the adjustment screws on the curved roller cage while moving the table as instructed in steps(7)and(8)Make sure not to reduce the preload too much.
(15) Finally, secure the b-curved tracking base at the adjustment screw side, which has been installed temporarily. Secure the rail mounting bolts on the curved roller cage one by one by moving the table as instructed above.

MOUNTING OF RVF TYPE
Installation ProcedureSetting the curved tracking bases temporarily
( 1 ) Remove burrs, stains, and dust from the installation surfaces of the curved tracking bases of tables and beds. Foreign particles must be kept out of the assembly work as well.
( 2 ) Apply low viscosity oil to contact surfaces, check the reference edges of an a-curved tracking base and bed, and then tighten the screws temporarily. (Figure G-38a)
( 3 ) Align the reference edges (NB mark side) of a b-curved tracking base and an a-curved tracking base to the same orientation. Then, insert the curved roller cages between the curved tracking bases at the center area. Make sure that the curved roller cages will not interfere with the curved raceway grooves of the curved roller tracking bases. (Figure G-38b)
( 4 ) Check the reference edge of the table, set the table over the b-curved tracking base, and then secure the table temporarily. (Figure G-38c)

SHAPE OF MOUNTING SURFACE
Slide way RVF and RV types are generally mounted by contacting the reference surface of the rail to the shoulder provided on the mounting surface. For the shoulder shape, provide relief at the corner as shown in Figure G-44 so that it does not interfere with the reference corner of the rail.If it is nessaray to mount RVF or RV types without relief, then it can be used with rounded corners as shown in Figure G-45. Table G-18 shows the corner radius of the mounting surface.

USE AND HANDLING PRECAUTIONS
LubricationNB gonio ways are lubricated using lithium soap No.00 based grease prior to shipment, so they can be used immediately. Make sure to relubricate with a similar type of grease periodically according to the operating conditions. NB also provides low dust generation grease for the linear system. Please refer to page Eng-41 for further details.
Dust PreventionIf a foreign matter, such as dust and dirt, enters the inside of the NB gonio way, it will deteriorate the accuracy and life of the system. A gonio way used in a harsh environment should be protected with a cover.
Operating EnvironmentThe recommended operating temperature range of the NB gonio way is ー20℃ to 110℃.
AdjustmentInaccuracy in mounting surface or improper adjustment of preload will reduce the motion accuracy, resulting in skewing and shortening of gonio way life. The adjustment should be carried out carefully.
Cage SlippageFor the NB Gonio Way, the cage can slip under high-speed motion, vertical application, unbalanced-loading, and vibrating conditions. It is recommended that the rotation range be set with sufficient margin and an excessive preload should be avoided. It is also recommended that the rails be cycled to perform the maximum stroke several times, so that the cage returns to its center position.
End PiecesEnd pieces are attached to each end of the NB gonio way to prevent removal of the curved roller cage. Do not use as a mechanical stopper.
Careful HandlingDropping the NB gonio way causes the rolling elements to make dents in the raceway surface. This will prevent smooth motion and will also affect accuracy. Be sure to handle the product with care.
Use as a SetThe accuracy of the rails has been matched within each set. Note that the accuracy will be affected when the rails of different sets are combined.
Allowable LoadThe allowable load is a load under which the sum of elastic deformation of the rolling element and the raceway in the contact area subject to the maximum contact stress is small enough to guarantee smooth rolling movement. When very smooth and highly accurate motion is required, make sure to use the product within the allowable load.
RVF TYPE 2 AXES AND SPECIAL SPECIFICATIONS
When incorporating RVF type units onto two axes as illustrated in Figure G-44, adjust the height of one lifting axis as instructed in Table G-17. Then, adjust dimension b (the height of the installation surface of the a-curved tracking base) in Figure G-44 according to the table in order to obtain the identical rotation center for the two axes. In addition, requests can be made for custom specifications including table units fitted for two axes, non-standard lengths for curved tracking bases, the radius of rotation, the rotation range, and the number of rollers. Contact NB for further information.
