Angular contact ball bearing

Angular contact ball bearing can withstand both radial and axial loads. Can work at a higher speed. The larger the contact angle, the higher the axial load carrying capacity. High precision and high speed bearing usually take 15 degrees contact angle. Under the action of axial force, the contact angle will increase.

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 bearing have a contact angle of 40 degrees, so they can withstand a large axial load. The angular contact ball bearing is a non-separate design with different shoulder heights on both sides of the inner and outer ring. In order to increase the load capacity of the bearing, one of the shoulders is machined lower, thus allowing the bearing to fit more balls.

Double row angular contact ball bearing can withstand large radial load-based radial and axial combined load and moment load, limiting the axial displacement of both sides of the shaft. 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, allow the tilt angle depends on the internal clearance of the bearing, bearing size, internal design and the role of the force and moment on the bearing, and allow the tilt angle should ensure that the bearing does not produce too high additional stress. If there is a tilting angle between the inner and outer ring of the bearing, it will affect the life of the bearing, and at the same time cause the running accuracy of the bearing to decrease and the running noise to increase.

Double row angular contact ball bearing generally use nylon keep frame or brass solid keep frame. Double angular contact ball bearing installation should be noted, although the bearing can bear two-way axial load, but if one side of the loading ball gap, should be careful not to let the main axial load through the side of the gap groove edge. In bearing use should pay attention to make without loading ball notch side of the raceway to bear the main load.

Single row angular contact ball bearing: machine tool spindle, high frequency motor, gas turbine, booster pump, drilling platform, food machinery, indexing head, welding machine, low noise type cooling tower, mechanical and electrical equipment, etc.

Double-row angular contact ball bearing: oil pumps, Roots blowers, air compressors, all kinds of transmissions, fuel injection pumps, food packaging machinery, welding machines, soldering irons, square boxes, gravity guns, inspection and analysis equipment, fine chemical machinery, etc.
