We designs and manufactures a variety of crossed roller bearings that can handle radial, thrust and moment loads at the same time. These compact bearings feature rollers crossed at right angles between inner and outer rings. Widely used in machine tools, industrial robots and Cross Roller Bearing medical equipment because of their high rotational accuracy. Roller guide options include a cage or separator as well as a full complement design. Both the cage and separator styles offer a small coefficient of friction for high-speed rotation. Full complement bearings handle heavy loads at low speeds. Sealed and KOYO 6304 Bearing open designs are available. Sealed bearings incorporate synthetic rubber seals to protect against dust, dirt and grease.A crossed roller bearing, also called a crossed roller slideway, is effectively two sets of. bearings and races combined at right angles to each other. Cylindrical bearings or rollers mount along the length of a rail in a carriage.
