Product Description

Product Description
The raceways of angular contact ball bearing in the inner and outer rings can have relative displacement on the horizontal axis. Therefore, this design can make it withstand combined loads, namely, supporting radial and axial loads simultaneously. The axial load capacity of angular contact ball bearing improves with the increasing contact angle. The contact angle is defined as the angle between the line joining the points of contact of the ball and the raceways in the radial plane, along which the load is transmitted from one raceway to another, and a line perpendicular to the bearing axis. The retainer is made of brass, synthetic resin of others subject to individual bearing's features and application conditions.

It uses axially asymmetric races. An axial load passes in a straight line through the bearing, whereas a radial load takes an oblique path that tends to want to separate the races axially. So the angle of contact on the inner race is the same as that on the outer race. Angular contact bearings better support "combined loads" (loading in both the radial and axial directions) and the contact angle of the bearing should be matched to the relative proportions of each. The larger the contact angle (typically in the range 10 to 45 degrees), the higher the axial load supported, but the lower the radial load
