Angular contact ball bearings

In these ball bearings, the direct line that connects the inner ring, balls, and outer ring has a given angle in the radial direction (the contact angle).

This angle is generally designed with three kinds of contact angle.

These bearings can bear axial loads, but because of the contact angle cannot be used singly and must be used in pairs or combinations.

Angular Contact Ball Bearings

Angular contact ball bearings have inner and

outer ring raceways that are displaced relative

to each other in the direction of the

bearing axis This means that these bearings

are designed to accommodate combined

loads, i e simultaneously acting radial and

axial loads

The axial load carrying capacity of angular

contact ball bearings increases as the contact

angle increases The contact angle is

deined as the angle between the line joining

the points of contact of the ball and the raceways

in the radial plane, along which the

combined load is transmitted from one raceway

to another, and a line perpendicular to

the bearing axis

The most commonly used designs are:

• single row angular contact ball bearings

• double row angular contact ball bearings

• four-point contact ball bearings
