ZZ Slewing Bearing is a company committed to becoming an international slewing bearing, the slogan is ingenuity manufacturing, service to the world.s.

Design features:
The internal configuration consists of cylindrical rollers in a v-shaped groove in each ring. The rollers are oriented with alternating axes of rotation. Positioned in this manner, the bearing accepts all combinations of radial, thrust, and moment loads. Rotational torque is less than a four-point contact ball design because each roller only transmits load in a single direction, and the greater contact area and geometry of a roller versus a ball provides a higher degree of stiffness and rigidity.

A roller of approximately the same size as a ball has greater load-carrying ability. However, because not all the rollers are oriented in one direction, their thrust and moment load capacity is less than that of a four-point ball bearing.
