    Cross-Roller Ring Series 
    Structure
    With the Cross-Roller Ring, cylindrical rollers are arranged crosswise, with each roller perpendicular to the adjacent roller, in a 90゜ V groove, separated from each other by a spacer retainer. This design allows just one bearing to receive loads in all directions including, radial, axial and moment loads.Since the Cross-Roller Ring achieves high rigidity despite the minimum possible dimensions of the inner and outer rings.
    Features
    Compact, Highly Rigid Swivel Bearings ,Achieving a Superb Rotation Accuracy
    Applications
    It is optimal for applications such as joints and swiveling units of industrial robots,
    swiveling tables of machining centers, rotary units of manipulators, precision rotary tables, medical equipment, measuring instruments and IC manufacturing machines
    Cross roller Bearings with different Structure

    Model RA (Separable Outer RingType for Inner Ring Rotation)


    RA series based on model RB,this type is a light and compact type with the thinnest inner ring and outer ring. It is optimal for location where weight reduction and downsizing are required,such as the hand swiveling unit of robots and manipulators.
