Crossed Roller Bearing - 8 mm Width, High Rigidity, CRBH Series【1-3 Pieces Per Package】
- Volume Discount
IKO Crossed Roller Bearigns are compact bearigns with their rollers alternatively crossed at right angles to each other between inner and outer rings. The rollres make line-contact with raceway surfaces, and, therefore, elastic deformation due to bearing loads is very small. They can take loads from any directions at the same time such as radial, thrust and moment loads. It is possible to make your design compact comparing to the usage of taper roller bearing and combination of two ball bearings. These bearrings are widely used in the rotating parts of industrial robots, machine tools, medical equipment, etc., which require compactness, high rigidity and high rotational accuracy.
