IKO High Rigidity Type Crossed Roller Bearings V CRBHV

IKO High Rigidity Type Crossed Roller Bearings V CRBHV

IKOCrossed 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.
