CRBH Cross Roller Bearings

The orthogonal arrangement of rollers forms a symmetrical contact line, evenly distributing radial, axial, and moment loads. The integral design of inner and outer rings reduces cumulative assembly errors and enhances system rigidity. Performance Features: Ultra-thin Cross-section: With a minimum cross-section height of 8mm, it suits the space constraints of micro devices. Low Friction: The roller end faces are precisely polished (Ra≤0.1μm), reducing energy consumption. Long Service Life: Surface hardening treatment of GCr15 material increases fatigue resistance by 30%. Customization Options: Support hybrid designs with ceramic rollers, non-standard sizes, and special lubricants for vacuum environments.

Roller Arrangement and Load Distribution: Orthogonal and crosswise rollers form an “X”-shaped contact line, evenly dispersing radial and axial forces. Moment loads are transmitted through diagonal rollers, reducing local stress concentration. Lubrication and Sealing: Double Seals (UU/U): Protect against dust and liquid intrusion, suitable for complex industrial environments. Thermal Management: The low-friction design reduces temperature rise (typical temperature rise ≤ 15°C), ensuring the thermal stability of precision instruments. Installation Compatibility: The integral structure of the inner and outer rings simplifies the installation process and is compatible with interference fits (shaft h6/housing bore H7).
