The outer ring of the Standard Type Crossed Roller Bearings is made of two split pieces, which are bolted together to prevent separation during transportation or mounting, enabling easy handling. These bearings are widely used in the rotating parts of industrial robots, machine tools, medical equipment, etc., which require compactness, high rigidity and high rotational accuracy. In addition, bearings made of stainless steel and those with inner and outer rings provided with mounting holes are also available on request.
● High Rotation Accuracy of RA 14008 Cross Roller Bearing/ CRBS 1408 Bearings
● Easy Handling
The inner and outer rings, which are separable, are secured to the Cross-Roller Ring body after the rollers and spacer retainers are installed. This procedure prevents the rings from separating from each other. Thus, it is easy to handle the rings when installing the Cross-Roller Ring.

6. Model RA-C (Single-Split Type)
Features of Crossed Roller Bearings RA 14008/CRBS 1408
1. Excellent rotation accuracy
2. Simplified operation and installation
3. Withstand large axial and radial loads
4. Significantly save installation space
5. High speed capability
6. Reduce shaft length and processing costs, thermal expansion causes limited changes in geometric dimensions
7. Adopt nylon divider, low moment of inertia, low starting torque, easy to control angle indexing
8. Optimize the pre-tightening force, the rigidity is large, and the guiding roller has high precision
9. Carburized steel provides excellent impact resistance and surface abrasion resistance
