Crossed Roller Bearings for High-rigidity Rotary Mechanisms

Application

Application Challenges

Structural Deformation

Bearing and housing deformation can reduce positioning and transmission accuracy.

Combined Loads

Rotary mechanisms often carry radial, axial and tilting moment loads simultaneously.

High Moment Capacity

Large overhung loads require strong resistance to tilting.

Accurate Rotation

High-rigidity mechanisms still require low runout and smooth torque.

Long-term Rigidity

Repeated loads must not cause excessive wear or preload loss.

Products

FAQ

Crossed Roller Bearings for High-rigidity Rotary Mechanisms FAQ

Please provide the application, bearing number or dimensions, radial load, axial load, tilting moment, speed, runout or accuracy requirement, mounting structure, quantity and drawing if available.

CHG provides RAU, RU, CRBH, RE, RB, SX and XSU series crossed roller bearings.

Yes. Custom solutions can be reviewed according to 2D/3D drawings, bearing numbers, mounting-hole patterns, dimensions, preload and application conditions.

Integrated mounting-hole types simplify assembly and improve rigidity, while separable structures may suit compact or existing housings. Final selection depends on ring rotation, mounting and load requirements.

Dimensional inspection, runout inspection, rotational torque or preload records, material certificates and product photos can be provided according to order requirements.
