Four-Point Contact Ball Bearings

Four point 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 VXO Explorer four point contact bearings have a recessed shoulder. This improves oil flow when the bearing is used in combination with an VXO cylindrical roller bearing (fig. 1). In addition, these recesses can be used to facilitate dismounting.

Features of 4 point contact ball bearing

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
