China Slewing Ring Bearing, Slewing Drive Suppliers & Manufacturers & Factory - Four point contact ball bearing stiffness

The stiffness of a rolling-element bearing is one of the main contributors to the transmission of force from the exterior loading to the slewing ring bearing itself. Many methods have been proposed to determine the bearing stiffness. The very compact design of a four-point contact ball bearing may lead to the concern that the load rating of a
