Crossed Roller Bearings for Optical Equipment

Application

Application Challenges

Optical Axis Stability

Small bearing deflection can affect beam alignment, image quality and tracking accuracy.

Very Low Runout

Optical systems require controlled radial and axial error motion.

Smooth Tracking

Tracking and scanning systems require low torque fluctuation and vibration.

Compact Packaging

Optical instruments often require a large clear aperture in limited space.

Environmental Stability

Temperature variation may influence alignment and preload.

FAQ

Crossed Roller Bearings for Optical Equipment 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.
