Tower Crane Slewing Bearing Crane Electrical Parts

The Tower crane slewing ring is the main part to help the tower crane do slew working. Usually, Tower Crane Slewing Bearing is made of 42-42CrMo, 40-40Cr or 50-50Mn material.

Slewing Ring for Tower Crane will be installed through the mounting hole. The diameter of the inner raceway and outer ring is required if you want to make one.

Slewing bearing is mainly made up of inner and outer rings. It features compact in design, and light in weight. The balls contact with the raceway at four points, via which the axial force, radial force and tilting moment may be transmitted simultaneously.

Our products prove every day to be important structural and connection elements used in wind turbines, excavators, mobile cranes, harbor and shipyard cranes, and in general mechanical engineering.

1. High qualified material, Stronger loading capacity, Larger radial and axial force bearing ability. Exquisite technological standard. We make sure that our comprehensive quality management system is in accordance with ISO9001 standards and is performed effectively.
2. The material adopts 42CrMo, Q+T, much longer life, 50Mn can be chosen by customer requirement. 
3. Large size slewing bearing, high Precision, slewing ring bearing precision can reach P4.
4. Delivery in time, our factory has a large batch of standard inner and outer ring forging for stock, which can shorten the delivery time to 7days.

We provide different types of slewing bearings for tower cranes, giving you the best choice.
