Angular Contact Ball Bearings


The raceway of both inner and outer rings of Angular Contact Ball Bearings is designed to maintain a specific contact angle between the balls and raceways, in the radial plane. Standard cage materials for this type are pressed steel, high strength brass or synthetic resin. In comparison to a Deep Groove Ball Bearing, Angular Contact type generally carries more number of rolling elements (balls), and is capable of sustaining radial, axial or composite loads.

Angular Contact Ball Bearings are classified into three sub-categories:

1. Single Row
They have three different contact angle classifications:
Contact Angle Symbol Contact Angle
A 30 degrees
B 40 degrees
C 15 degrees
AC 25 degrees


2. Double Row
They have two different contact angle classifications:
Contact Angle Symbol Contact Angle
None 20 degrees
A 30 degrees


3. Combination Type
Generally, Single Row Angular Contact Ball Bearings are used in combination of two or more units. Three different combinations are available:
Configuration Load Capacity
Back-to-back Bi-directional axial
Face-to-face Bi-directional axial
Tandem Uni-directional axial

KG can offer the following variants:
