As the result of pursue of absolute weight saving, the weight of this type is greatly reduced down to 0.38 of the conventional slim type CRBS. (Shaft diameter : 50 mm)
Perpendicular arrangement of cylindrical rollers enables a single bearing to take complicated loads such as radial, axial and moment loads.Since this type of bearings can be used in a cantilever structure, they can increase the degree of freedom in designing and contribute to device downsizing and space saving.
CRBSSuper Slim & Slim Type Crossed Roller Bearing are extremely compact bearings having cylindrical rollers disposed perpendicularly between inner and outer rings. A single bearing can take complicated loads such as radial, axial and moment loads.By using cylindrical rollers whose elastic displacement due to load is smaller than steel balls, this type of crossed roller bearing can make the device compact and highly rigid comparing to ball bearings or taper roller bearings and the combination of two ball bearings.These bearings are widely used in the rotating parts of industrial robots, optical apparatus and medical equip-ments, etc., which contribute compactness and lightness.

Load Rating and Life
Basic dynamic load rating C
The basic dynamic load rating is defined as a constant radialload both in direction and magnitude under which a group ofidentical bearings are individually operated and 90% of thebearings in the group can rotate 1,000,000 revolutions freefrom material damage due to rolling contact fatigue.
Life
The basic rating life of Super Slim and Slim TypeCrossed Roller Bearings is obtained from the followingformula.
where, L10 ： Basic rating life, 106rev.
C ： Basic dynamic load rating, N
Pr ： Dynamic equivalent radial load, N
If the number of revolutions per minute is known, the rating
life in hours can be obtained from the following formula.
where, Lh ： Basic rating life in hours, h
n ： Number of revolutions per minute, rpm
Life in oscillating motion
When a bearing is used in oscillating motion, the life can be
obtained from the following formula.
where, L0c ： Basic rating life in oscillating motion
106cycles
2θ ： Oscillating angle, degrees (Refer to Fig.1.)
Pr ： Dynamic equivalent radial load, N
If the number of oscillations per minute n1cpm is given, the
rating life in hours can be obtained from Formula (2) by
substituting n1 for n.
When the oscillating angle 2θ is small, oil film may not be
formed between the rolling elements and the raceways and
fretting corrosion may occur. In this case, please consult
.
Limitations of life formulae
These life calculation formulae are applicable when themounting and lubrication of bearing are normal and thebearing is used without intrusion of foreign matters under anormal operating condition and not under an extreme severecondition.If these conditions are not satisfied, the actual life maydecrease rapidly.For example, it is necessary to consider the additional factors,such as deformation of bearing by miss-mounting, largedeformation of housing/shaft, large preload and use ofunsuitable grease.Furthermore, when the dynamic equivalent radial loadexceeds 1/2 of the basic dynamic load rating, the lifecalculation formulae may not be used.
Dynamic equivalent radial load
The dynamic equivalent radial load of Super Slim andSlim Type Crossed Roller Bearings can be obtained from thefollowing formula.
where, Pr ： Dynamic equivalent radial load, kgf
Fr ： Radial load, N
Fa ： Axial load, N
M ： Moment, N・mm
Dpw ： Pitch circle diameter, mm
X ： Radial load factor (Refer to Table 3.)
Y ： Axial load factor (Refer to Table 3.)

a prescribed contact stress at the center of contact area
between rolling elements and raceways on which the
maximum load is applied.
Static safety factorThe static safety factor fs, of Super Slim and Slim Type
Crossed Roller Bearings can be obtained from the following
formula, and general values of this factor are shown in Table 4.
where, fs ： Static safety factor
C0 ： Basic static load rating, N
P0r ： Static equivalent radial load(maximum load), N

Dpw ： Pitch circle diameter, mm
Load factorActual loads applied to the bearing sometimes exceed the load

Accuracy
Dimensional accuracy and rotational accuracy of
Super Slim and Slim Type Crossed Roller Bearings are
shown in Tables 6.1 and 6.2. Bearings with special accuracy
are also optionally available. Please consult .
1N=0.102kgf=0.2248lbs.1mm=0.03937inch 87
In Super Slim Crossed Roller Bearing, fit based on the
actual measured dimensions of the bearings is
recommended. And those of Slim Type Crossed Roller
Bearings with normal clearance are shown in Table 8. For
the interference fit, the radial internal clearance after the fit is
decreased by approximately 70% to 90% of the interference
amount. To avoid excessive preload due to f i t , i t is
recommended to use a slight interference fit adjusted to the
actual measured dimensions for both T1 and C1 clearances.
Allowable rotational speeds of Super Slim and Slim
Type Crossed Roller Bearings are affected by mounting and
operating conditions. The values in general operation are
shown in Table 9.
Fit
Rotational torque of Super Slim and Slim Type
Crossed Roller Bearings are lower than that of plain bearings
and the difference between the static torque and the dynamic
(kinetic) torque is small. Therefore, these bearings minimize
power consumption and operating temperature rise of
machinery and increase the overall efficiency of machines.
The rotational torque is affected by many factors, but the
following formula can be used expediently.
where, T ： Rotational torque, N・mm
μ ： Friction coefficient (Approx. 0.010)
P0r ： Static equivalent radial load, N
Dpw： Pitch circle diameter, mm
When the radial clearance after mounting is a large minus
value, consult .
For Super Slim and Slim Type Crossed Roller Bearings,
oil hole and oil groove are not provided. However, for Slim
Type Crossed Roller Bearings, oil holes can be made upon
request. When oil holes are required on the outer ring, attach
“－nOH” before the clearance symbol in the identification
number. For an oil hole on the inner ring, attach “／nOH”.
When the rigidity of the mounting parts is not sufficient, stress
concentration will occur at the contact area between the
rollers and raceways, and the bearing performance will be
deteriorated significantly.
Therefore, it is necessary to carefully examine the rigidity of
housing and the strength of fixing bolts when a large moment
is applied.
The shoulder height diameters (da and Da) that are related to
mounting should certainly satisfy the values shown in the
dimension tables. When these dimensions are not
appropreate, deformations of inner and outer rings will occur
and the bearing performance will be deteriorated remarkably.
Rotational torque
These bearings are generally lubricated with grease. In re-
lubrication, grease is supplied through the gap between the
outer ring and inner ring.
For grease prepacked bearings, ALVANIA EP grease 2 (by
Shell) is prepacked. (Refer Table 10) For bearings without
prepacked grease, supply grease or oil for use. Operating
without grease or oil will increase the wear of the rolling
contact surfaces and cause a short bearing life.
When using special grease, carefully examine the grease
properties and contents such as base oil viscosity and
extreme pressure addit ives. In this case, please
contact .

Fig. 3 Mounting example
●1 The inner and outer rings should be securely fixed in the
axial direction by using fixing plates, etc. Recommended
thickness of the fixing plate is 1/2 or more of the bearing
width (B). The dimensions in axial direction of the housing
bore and the fixing plates should be decided to get a
secure fixing while considering the actual dimension of
bearing width which is zero/minus-tolerance. (See Fig.3)
●2 The depth of housing bore is recommended to be the same
to or larger than the bearing width.
●3 Bearing has a plug for hole for inserting cylindrical rollers.
When mounting the bearings, located the plug at a position
that is not included in the maximum loading zone. The plug
location can be found by the pin that is at the side of the
outer ring.
