Crossed Roller Bearings are compact bearings with their rollers alternately crossed at right angles to each other between inner and outer rings. They can take loads from any directions at the same time such as radial, thrust and moment loads. The rollers make line-contact with raceway surfaces, and, therefore, elastic deformation due to bearing loads is very small.
Rollers are arranged by intersecting orthogonally between inner ring and outer ring of the single structure. A separator, which can smoothly rotate rollers, is incorporated between rollers.
Crossed Roller Bearings have an open type and a sealed type. With the sealed type, special synthetic rubber sealing is incorporated.
