Four-point Angular Contact Ball Bearings

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 2 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 of Four-point Angular Contact Ball Bearings

-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 Angular Contact Ball Bearings

A four-point angular contact ball bearing simplifies machine designs that combine radial, thrust, and moment loads because it can handle all 3 simultaneously. They are primarily used for slow to moderate-speed applications or where oscillatory movement is predominant.

Four-point angular 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.
