Description
Specification

Cross roller slewing bearings are engineered to support combined axial, radial, and tilting moment loads with exceptionally high rigidity and precision. Featuring cylindrical rollers arranged in a crossed pattern at 90 degrees to each other, this bearing design allows each roller to handle load independently, providing outstanding load capacity and uniform stress distribution within a compact structure.

The optimized raceway geometry enables cross roller slewing bearings to simultaneously withstand axial loads in both directions, radial forces, and overturning moments, making them ideal for applications that require high positioning accuracy and smooth rotational performance. Compared with ball-type slewing bearings, cross roller designs offer greater stiffness, improved rotational accuracy, and enhanced resistance to deformation under heavy loads.

Manufactured from premium bearing steel with precision-ground raceways, these slewing bearings ensure low friction, stable operation, and long service life even under continuous or high-impact conditions. They are widely used in industrial robots, precision rotary tables, machine tools, medical equipment, cranes, and excavators where reliability, compact design, and high accuracy are critical.

Available with internal or external gear options and customizable sizes, cross roller slewing bearings provide a robust and efficient solution for demanding rotational systems requiring high load capacity and precise motion control.
