Their rollers 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 linear contact with the surface of the track, 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 a cross-roller bearing, a cylindrical roller is placed perpendicular to each other by a spacer on a 90° V-groove rolling surface, so one cross roller bearing can withstand Loads in all directions, such as radial load, axial load and moment 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 a robot rotating part, a precision rotary table, a medical device, a meter, and an IC manufacturing device.
