Crossed Roller Bearing

This crossed roller bearing has a compact, integrated structure that targets high-precision rotary motion applications. It uses alternately arranged cylindrical rollers at a 90° angle between the inner and outer rings. This design lets the bearing simultaneously support radial loads, axial loads, and moment loads from multiple directions.

The bearing delivers exceptional rotational accuracy and rigidity in a minimal footprint. Evenly distributed rollers minimize elastic deformation under load, so the bearing maintains stable performance even under combined loading conditions. You can apply preload during assembly to eliminate backlash, which further boosts stiffness and precision for demanding positioning tasks.

Manufacturers use high-grade bearing steel and precision-ground raceways to build the bearing for long service life and reliable operation. Its single-unit design simplifies installation and alignment, unlike multiple bearing configurations. It fits use cases including CNC rotary tables, industrial robots, and precision medical equipment where compact size and high accuracy are critical.
