There is 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. Crossed roller bearings are most commonly used in machine tools, industrial robots and medical equipment due to 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 are designed to handle heavy loads at slower speeds.
Sealed and open designs are available. Sealed type bearings incorporate synthetic rubber seals to protect against dust, dirt and grease.
