Overview of CRBS Series Crossed Roller Bearings

Compact & Lightweight Structure

The CRBS series features an ultra-thin cross section with a small outer diameter relative to the inner diameter, along with a narrow width. This makes them highly suitable for compact mechanical designs where installation space is limited, and weight reduction is crucial.

Multiple Configuration Options

CRBS bearings are available in caged, separator, and full complement types, allowing users to select the most appropriate design based on speed, load, and operational stability requirements:

Caged Type: Offers high-speed performance and minimal friction.
Separator Type: Provides a balance of speed and load capacity.
Full Complement Type: Maximizes load capacity but is better suited for lower-speed applications.

Simultaneous Multi-Directional Load Handling

Like all crossed roller bearings, the CRBS series can support radial, axial, and moment loads simultaneously. This multifunctionality reduces the need for multiple bearing arrangements and enhances design efficiency.

High Rigidity & Rotational Accuracy

Despite the slim profile, these bearings maintain excellent rigidity and precision due to their internal 90° V-groove design and orthogonally arranged cylindrical rollers. The result is stable, smooth rotation under demanding conditions.
