Angular Contact Ball Bearing

Angular contact ball bearings have raceways on the inner and outer rings, and the inner and outer rings can be displaced along the axial direction of the bearing. This kind of bearing is especially suitable for bearing compound load, that is, radial and axial at the same time the role of the load. Angular contact ball bearing axial load bearing capacity with the increase in contact angle α and increase. Contact angle for the radial plane of the ball and raceway contact point line and bearing axis of the vertical line between the angle.

Single row angular contact ball bearing can only bear a direction of the axial load, in bearing radial load, will cause additional axial force. And can only limit the shaft or shell in a direction of axial displacement. Angular contact ball bearings have a contact angle of 40 degrees, so they can withstand a large axial load.

Double row angular contact ball bearing can bear a large radial load mainly radial and axial combined load and moment load, to limit the axial displacement of the shaft in both directions. Mainly used to limit the shaft and shell two-way axial displacement of the components in the double row angular contact ball bearing between the inner and outer ring can be tilted limited, the allowable tilt angle depends on the internal clearance of the bearing, bearing size, internal design and the force and moment acting on the bearing, and the maximum allowable tilt angle should ensure that the bearing does not produce too high additional stress.
