Crossed Roller Bearings for Machine Tools

Application

Application Challenges

Machining Rigidity

Cutting forces and overhung workpieces create radial, axial and moment loads.

Indexing Accuracy

Axis positioning requires low runout and repeatable angular location.

Compact Axis Design

Multi-axis machines require high load capacity in limited space.

Shock & Reversing Loads

Tool entry, braking and rapid axis reversals create transient loads.

Coolant & Contamination

Machine tool environments may expose bearings to coolant and chips.

FAQ

Crossed Roller Bearings for Machine Tools 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.
