Crossed Roller Bearings for Medical Equipment

Application

Application Challenges

Positioning Accuracy

Imaging and treatment systems require stable and repeatable angular positioning.

Smooth & Quiet Motion

Medical environments require controlled torque, vibration and acoustic performance.

Compact Mechanisms

Equipment must combine large openings or motion ranges with limited installation space.

Patient & Equipment Loads

Rotary systems may carry patient weight, imaging modules or treatment heads.

Cleanliness & Reliability

Long service intervals and clean operation are important in medical equipment.

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.
