Crossed Roller Bearings for Precision Rotary Tables

Application

Application Challenges

Rotational Accuracy

Table indexing and machining accuracy depend on low radial and axial runout.

Tilting Rigidity

Workpiece and fixture overhang generate tilting moments on the table.

Drive Integration

Direct-drive, worm gear or reducer-driven tables require different bearing interfaces.

Smooth Indexing

Indexing and contouring require low torque fluctuation and stable motion.

Thermal Stability

Heat from motors and machining can influence preload and runout.

FAQ

Crossed Roller Bearings for Precision Rotary Tables 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.
