CRBT

Overview of CRBT Series Crossed Roller Bearings

Super Compact and Lightweight Design

The CRBT Series is specifically engineered for extreme compactness, with outer ring heights as low as 5.5 mm and widths as narrow as 5 mm. This makes them ideal for downsizing machines and reducing overall system weight without compromising rigidity or precision.

Without Mounting Holes

This series is designed without mounting holes, enabling greater flexibility in installation and integration into customized housing structures. It is best suited for applications where the bearing can be clamped externally or held in place by other mechanical constraints.

Smooth Rotation and High Rigidity

Cylindrical rollers are arranged orthogonally in a 90° V-groove, with precision-machined separators placed between them to ensure even load distribution and reduce friction. This structure ensures high rigidity and stable, smooth rotation even under multi-directional loads.
