IKO CROSS ROLLER BEARINGS IKO CRW 6-150 CRW 1-80 CRW 6-200 CRW 6-250 Crossed Roller Bearings are compact bearings with thier 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 load. The rollers make line conatct with raceways surfaces and therefore, elastic deformation due to bearing loads is very small.These bearings are widely used in the rotating parts of industrial robots, machine tools, medical equipments etc.which require compactness, high ridigity and high rotational accuracy.
