ROLLER GUIDE This linear motion system is based on the well known crossed roller design. A high level of High rigidity is achieved through a geometric design that permits a tight pitch and nearly 100% use of the roller length. The truly optimal interface of roller and cage reduces drag to a minimum and allows fully stick-slip free, high precision positioning and rapid stroke movement without heat build-up.

Linear Crossed Roller Guides

Features

Quality

UNION TOOL uses specially treated steel with all parts completely hardened to the core and diamond ground to within narrow tolerances. Raceway surfaces attain a mirror-like finish. Hardness Rail 58‐64HRC

Roller 58‐64HRC

Super Finish (SF)

UNION TOOL crossed Roller Guides are known for their high quality and precision. In applications demanding the highest performance, UNION TOOL offers Super Finish. To achieve this, special facilities have been created to produce a never before attained level of precision. • Surface are diamond to tolerances of half that of regular

precision with surface roughness of 0.1a. • Flatness of V-chasm surface is excellent. You can see

interference fringes with an optical flat and the block gauge is ringed.

• Fluctuation of the roller diameter is less than 0.5µm within a series of cages. (It is less than 2μm for the standard product.)

• Parallelism of V-chasm surface has been improved dramatically as in the following picture

Precision

The graph below shows the maximum tolerance of the dimension between the guide rail reference surface and the raceway. The high accuracy of each part provides smoother, more precise slide movement and long service life. Tolerance of roller outer diameter is within 1µm.

How to determine lengths The following two relationships give the length of the guide rail L and that of the roller cage l for the desired stroke S. 1. Generally S=2*(L ‐ l) 2. For a given rail length L, the following proportions are recommended： When S < 400mm then S/L = 1/1.5 ~ 1/2 When S > 400mm then S/L ≤ 1

When ordering :

1. When ordering a standard set, specify as : G6‐350 1 set. A standard set consists of four guide rails, two roller cages and eight end pieces. The roller cage as supplied has a length of approximately 80% of the guide rail and must be cut to the required stroke before use. 2. As a general rule, the roller cage is not available as a separate piece.

Guide Rail Type W The Wide rail with raceways on each side is easily mounted and fits standard RG rails to form a high precision table.

Since its elastic deformation at the contact point of the raceway surface is less, we can obtain more stable running precision, higher rigidity and longer duration of the raceway surface. (2) Smooth and Silent Run When running a ball or roller without a cage, a slipping phenomenon is generated between mutual rolling elements which may cause fluctuation of motion by low running or problems such as ball slippage and so on. TGH, having a roller as the rolling element, is retained by a chain-type cage, so these types of problems can be prevented from occurring and it can provide a silent, smooth and stable running. (3) Rails Processed in High Precision with fewer curves Having a roller as the rolling element, the raceway surface becomes a V-surface at a 90º angle. Since this V-surface is composed of one pair of surfaces, a higher precision process is possible compared to that of the R-type raceway surface using a ball, which makes it possible for users to use a high precision rail in stable quality.

Quality

For this product, carefully-selected special high grade metal, a high precision polish finishing process, and an equal heating process using a high grade hardening method are used. The guide surface of the roller is applied with a special finishing method to create a mirror-like surface to insure the achievement of smooth motion. Hardness Rail : 58 – 64 HRC Roller Material : 58 – 64 HRC

Lubrication

When the product is newly purchased, grease of lithium soap group is applied to the product. Even if we use high quality grease, it would deteriorate according to the time of operation and it is necessary to apply grease according to the condition of operation. As an approximate standard, please apply grease for every 100km of operation.

Assembly of Linear Motion Crossed Roller Guides 1. The guide rail mounting surfaces

of the table must be lightly finished with an oil stone then lightly oiled.

2. Place the guide rail on the

mounting surface and insert the mounting screws in the oversized holes of the guide rail. Then, gently move the guide rail right and left until the screws are concentric with the oversized holes. If the hole wall is in contact with the screw, the guide rail will be subjected to undesirable force with the result that the desired accuracy may not be attained.

3. Camp the guide rail with care

being exercised not to produce a spacing between it and the mounting surfaces. Tighten the screws securely

Caution： 1. First tighten the screw at

the center and work towards the ends alternately. If the screws at both ends are tightened initially the center portion of the guide rail may be deflected.

2. All rails must be firmly attached except the preload rail which is only loosely fastened at this point (Dia.1).

4. Assemble the upper and lower members of the table and insert the roller cages. If possible, the two roller cages should be positioned so that they are symmetric about the center line of the table (Dia.2).

5. Mount the end Pieces. 6. Apply preload to the degree that no play is produced between the

upper and lower members of the table. Preload must be applied only to the portions of the guide rail where the roller cage is sandwiched. If preload is imposed on portions where the roller cage is not supplying a counterforce, the guide rail may be damaged. In (Dia.3‐1), reload must not be applied at points 4 & 5.Move the table

as shown in (Dia.3‐2) before applying preload at these point 7. After completion of preload adjustment, the

preload guide rail must be fixed tightly with screws.

The purpose of preload is to crush the roller to some extent. Unless applying preload when the roller is at the back side, the preload does not increase to the desired level, and it may cause trouble. Please be careful. Follow the same procedure to fix the preload rail mounting bolt after applying preload.

Assembly of RGH / TGH 1. Mounting Guide Rail and Half Rail ( Picture 1).

A. Remove dirt from the rail and the surface of the bed mounting surface. B. Place the rail on the bed by aligning the mounting standard surface for the rail. C. Insert bolts in all the grooves in a way that the rail can still move freely. D. Move the rail slightly by sticking it to its mounting standard surface, make sure that there is no interference between the grooves and bolts, and then decide on the position. E. Clamp at the position of (1) groove, and fully tighten the bolt (1). F. Tighten (2), (3) and other bolts in the same way.

2. Mounting Unit Rail and V-Unit (Picture 2).

A. Remove dirt from the mounting surface. B. Place the unit on the mounting surface, let it stick to the mounting surface so the bolt can be placed at the center of the groove and lightly tighten it. C. Clamp the center of the V-unit and fully tighten the bolt.

3. Mounting Table and Base ( Picture 3-1, 3-2).

A. Insert the table into the base so the mounting bolt of the unit at the side of preload can

be placed at the center, and lightly tighten the bolt. When inserting the table into the base, be careful not to push the roller chain too much. B. Lightly tighten the preload bolts in the order

shown in the picture. Do not run the table until this has been completed. If you run the table when the roller is not in a right position, the roller chain may be damaged. C. Fully tighten the preload bolts in the order shown in the picture. D. Fully tighten the V-unit mounting bolts in the order shown in the picture. (When you want to pull the table, do it in the condition that preload is completely open.)
