Crossed roller bearings

Inside a crossed roller bearing, the cylindrical rollers are arranged perpendicular to the adjacent roller in a 90º V-groove and separated from each other by a retaining ring. This design allows just one bearing to support loads in all directions, including radial, axial and moment loads.

Because the crossed roller bearing offers high rigidity despite the smallest possible inner and outer ring dimensions, it is ideal for applications such as industrial robotics joints and pivot points, machining center pivot points, robotic arm pivot points, precision rotary tables, cranes, medical equipment, measuring instruments and machines for IC production.
