Four-point Angular Contact Ball Bearings

Four-point contact ball bearing is radical single row angular contact ball bearing, whose specially-designed rollaway nest can bear the axial loads in two directions. When the axial load is given, the bearing radical load shall be limited. The axial space taken up by this bearing is smaller than that of double row angular contact ball bearing.

Bearings Datas

Four-point angular contact ball bearings are radial single row angular contact ball bearings with raceways that are designed to support axial loads in both directions. For a given axial load, a limited radial load can also be supported (Load ratio). The bearings are separable, i.e. the outer ring with ball and cage assembly can be mounted separately from the two inner ring halves. Both inner ring halves of four-point contact ball bearings have a recessed shoulder. This improves oil flow when the bearing is used in combination with a cylindrical roller bearing. In addition, these recesses can be used to facilitate dismounting.

Features and Benefits

  • 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.

Applications of Four Point contact ball bearings

A four-point angular contact ball bearing makes it easy to simplify machine designs that have a combination of radial, thrust, and moment loads because it can handle all three simultaneously. They are primarily used for slow to moderate-speed applications, or where oscillatory movement is predominant. Four-point contact ball bearings are used in various applications, for example:

  • Agricultural machinery;
  • Earthmoving machinery;
  • Pumps;
  • Industrial machinery for cleaning and bottling;
  • Electric motors;
  • Fitness machines;
  • Machining equipment (steel, glass, marble, wood,);
  • Automatic opening systems;
  • Others.
