Cross roller bearing introduction and description

    Cross-roller bearings, the rollers of which are arranged at right angles to each other at intervals between the inner and outer wheels. They can withstand loads from all directions (such as axial, thrust or momentum loads). Since the roller is in contact with the track surface, the bearing is less likely to be elastically deformed by the load.
    This type of bearing is widely used in industrial robots, work machines and medical facilities, where high rigidity, tightness and high speed are required to ensure accuracy.
    In the cross-roller bearing, since the cylindrical rollers are vertically arranged by the spacers on the V-shaped groove rolling surface of 90°, one cross roller bearing can withstand radial load and axial load. And load in all directions, such as torque load.
    The size of the inner and outer rings is miniaturized to a minimum, and the extremely thin type is a small size close to the limit and has high rigidity, so it is most suitable for a joint portion or a rotating portion of an industrial robot, a rotary table of a machining center, Uses such as robot rotating parts, precision rotary tables, medical equipment, gauges, and IC manufacturing equipment.
