CRBS Crossed Roller Bearings are a type of high-precision rotary bearing designed to handle combined loads (radial, axial, and moment loads) simultaneously with exceptional rigidity and accuracy. The unique 90° crossed roller arrangement ensures optimized load distribution, making them ideal for applications requiring high rotational precision, compact design, and low deflection.
Key Features:✔ High Load Capacity – Supports radial, axial, and moment loads in a single bearing.
✔ Compact & Space-Saving – Integrates two bearing functions into one unit, reducing assembly size.
✔ Smooth Rotation with Low Friction
