Product Details



Cross-tapered roller bearing is a kind of deformation of crossed cylindrical roller. Its rolling body is cone and adjacent rollers are arranged at 90 degrees. The bearing is characterized by pure rolling during the movement and avoids sliding. Therefore, The rotational speed of the crossed tapered roller bearing is much higher than that of the crossed cylindrical roller bearing, but the friction torque is lower than that of the crossed cylindrical roller bearing.
