In the field of heavy machinery, slewing bearings (also known as slewing ring or turntable bearing) play a crucial role in the rotation and stability of cranes. Whether it is a car crane, tower crane, or crawler crane, this component is responsible for bearing enormous axial, radial, and moment loads while ensuring smooth and precise rotation.

The slewing bearing on the crane connects the upper structure (boom and cab) and the lower chassis. It enables the crane to rotate 360 degrees while lifting heavy objects. This rotation function enables operators to accurately and safely position the load. If there is no slewing bearing, the crane will lose flexibility and operational efficiency.

Xuzhou Wanda slewing bearing co., ltd., designed and manufactured slewing bearings for cranes, with excellent precision and durability. Our products use advanced materials and strict quality control to ensure a long service life even under extreme working conditions. Each XZWD slewing bearing undergoes strict heat treatment, gear hardening, and sealing processes to ensure excellent performance even in dusty, humid, or high-temperature environments.

How does the slewing bearing on the crane work?

The slewing bearing consists of an inner ring, an outer ring, rolling elements (balls or rollers), and a gear mechanism. Gears (internal or external) enable the drive motor to smoothly rotate the upper structure of the crane. Rolling elements reduce friction and ensure easy rotation even under heavy loads.

The slewing bearings for cranes produced by Xuzhou Wanda adopt optimized raceway geometry design, which can improve load distribution and minimize wear to the greatest extent possible. This ensures stable rotational performance and reduces maintenance costs.

The main advantages of the slewing bearing of the crane produced by XZWD
