CRBF Series Crossed Roller Bearings

Key Features of CRBF Series Crossed Roller Bearings

1. Multi-Directional Load Support

CRBF bearings utilize cylindrical rollers arranged orthogonally on the raceway, enabling them to withstand radial, axial, and moment loads simultaneously. This makes them suitable for complex loading conditions found in robotics and automation equipment.

2. One-Piece Ring Structure for High Rigidity

Both the inner and outer rings of CRBF bearings are machined from a single solid piece, delivering excellent rigidity and superior rotation accuracy. This structure also minimizes the influence of mounting errors, enhancing bearing performance and simplifying assembly.

3. Face-Mount Design for Easy Installation

Thanks to the integrated mounting holes on both the inner and outer ring faces, CRBF crossed roller bearings can be bolted directly onto related components. This eliminates the need for additional housings or fixing plates, resulting in a compact and lightweight design.

4. Custom Mounting Hole Designs Available

To accommodate diverse installation needs, Corebearing offers various mounting hole configurations for the CRBF series. This flexibility allows customers to integrate the bearing seamlessly into their specific applications.
