Four-point Contact Ball Bearing Turntable with Deformable Rings for Crane

The four-point-contact ball bearing is a single row angular contact bearings designed to handle two-directional axial loading. These bearings require a minimum amount of space and can be custom designed to meet our customer's unique loading parameters. And the four-point-contact ball bearings can carry either pure axial loading or combined loading provided the axial component is more significant.

For heavy industrial requirements, this style of bearing can be designed as a large slewing ring bearing with bolted down races and internal or external integral gearing.

1. Defination 

1) Slewing Bearing is a kind of comprehensive load which can be withstand the larger axial and radial load and tilting moment.

2) Standard : JB/2300-1999 and JB/2300-2011

3) Application: Widely used in Marine equipment, engineering machinery, light industry, machinery, metallurgical machinery, medical machinery, industrial machinery and other industries

2. Basic Structure

Slewing bearing is consisted of worm, slewing bearing, shell, motor and other components.Because core part USES the rotary bearing, can also carry axial force and radial force and Titing moment.

1. From left to right ( upper part ) 

1) The outer ring (teeth or no teeth) 

2) The sealing tape 

3) Rolling body (ball or roller) 

4) Refueling mouth
