VLU200844 734x948x56mm Four point contact slewing bearings China bearing custom made

Description

Four-point contact ball bearings are radial single row angular contact ball slewing bearings with raceways that are designed to handle two-directional axial loading. These 4 point contact ball bearings require a minimum amount of space and can carry either pure axial loading or combined loading. For heavy industrial requirements, 4 points contact ball style of ring can be designed as a large slewing ring bearing with bolted down races and internal or external integral gearing. Four-point contact ball bearing can handle all three simultaneously, which makes it easy to simplify machine designs that have a combination of radial, thrust and moment loads. 

Material:

The materials of the four-point contact ball bearing are mainly 50 Mn, 42CrMo and C45.

Applications:

1. Slewing conveyor

2. Welding manipulator 

3. Light and medium duty cranes (truck mounted crane, deck crane, aerial platform truck etc.)

4. Different excavators
