Overview of Angular Contact Ball Bearings
There are raceways on the inner and outer rings of angular contact ball bearings, and the inner and outer rings can be mutually displaced along the axial direction of the bearing.This kind of bearing is especially suitable for bearing compound load, namely, radial and axial simultaneous action of the negative load.
The axial load bearing capacity of angular contact ball bearings increases with the increase of contact Angle α.The contact Angle is the Angle between the contact point line of the ball and the raceway in the radial plane and the vertical line of the bearing axis.
Features of Angular Contact Ball Bearings
General purpose assembly bearings are specially engineered so that when the bearings are mounted close to each other, any combination can achieve a given internal clearance or preload, as well as an average load distribution, without the use of gaskets or similar devices.
Applications of Angular Contact Ball Bearings
Single row angular contact ball bearings: machine tool spindle, high frequency motor, combustion steam turbine, centrifugal separator, small car front wheel, differential pinion shaft.
Double row angular contact ball bearings: oil pump, Roots blower, air compressor, all kinds of transmission, fuel injection pump, printing machinery.
Classification of Angular Contact Ball Bearings
There are several types of angular contact ball bearings: Type 7000C (∝=15°), Type 7000AC (∝ 25°) and Type 7000B(∝ 40°)
