Crossed Roller Bearings

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. These bearings are widely used where they require compactness, high rigidity and high rotational accuracy. In addition, bearings made of stainless steel or those with inner and outer rings provided with mounting holes are also available.
