load distribution in a four point contact slewing bearing

The single row four point contact ball slewing bearing is composed of two seat rings, which design in compact structure and light weight, steel ball contact with the circular raceway at four point, it can bear the axial force, radial force and the tilting moment at the same time.

The bearing capacity curve of 4-point contact slewing bearing

Each type of slewing bearing of product samples has a corresponding load-carrying capacity curve, and the graph can help the user to select the slewing bearing preliminarily.

Below is the load curve of light slewing ring, 011.30.900.

The Company selects the most suitable materials to manufacture slewing bearings to adapt to foreseeable purposes. These materials are manufactured by a recognized steel plant. To ensure product quality, every step in the process is inspected. Tempering heat treatment is needed when the product is subject to high stress. Customers can select materials from the following tables. Composition of two materials and two heat treatment states: 50MnT, 42CrMoT, with mechanical performance ranking from low to high. Customers can also specify other materials designations according to their needs.
