CRBC09020 bearings ( 90 mm x 140 mm x 20 mm) have the advantages of The rollers are arranged in a cross pattern, allowing them to withstand radial, axial, and overturning moments simultaneously. They offer high rigidity and rotational accuracy while compact and space-saving design, and easy installation, and are therefore widely used in the Industrial robots, CNC machine tools, medical equipment, precision measuring instruments and aerospace.

The CRBC09020 Crossed roller bearings consist of inner and outer rings, cylindrical rollers, spacers, and seals. The rollers are arranged at 90° intervals within a V-shaped raceway, allowing for multi-directional load bearing even in a single row.
Crossed roller bearings can simultaneously withstand radial loads, bidirectional axial loads, and overturning moments. They possess extremely high rigidity and rotational accuracy, and their compact structure saves installation space, simplifying machine tool design.
