GCr15 Single Row Ball Slewing Bearing Four Point Contact For Excavator

Four Point Contact Ball Slewing Bearing

The Single-row Four-point Contact Ball Slewing Bearing consists of two seating rings. It is characterized by compact structure, light weight and four-point contact between the steel balls and the arc raceway. It can bear axial force, radial force and overturning moment simultaneously.

Slewing Bearing Details

1. Inner Ring
2. Outer Ring
3. Seal
4. Spacer
5. Ball/Roller

Advantages:

• Accommodates axial loads in both directions

• Less axial space

• These bearings take up considerably less axial space than double row bearings.

• High load carrying capacity

• A large number of balls are incorporated, giving the bearing its high load carrying capacity.

• Separable design

• The split inner ring leads to easier mounting and dismounting of the bearing.

• Improved oil flow

• Limited inner ring deformation when subjected to high clamping forces

Application:

Single row four point contact ball slewing bearings are widely used for the following applications:

Excavator

Crane

Rotary conveyor

Port machinery

Wind power generation

Amusement facilities
