The angular contact steel ball bearing can withstand both radial and axial loads. It can work at a higher speed. The higher the contact angle, the higher the axial bearing capacity. High-precision and high-speed bearings usually take 15 degrees of contact angle. Under the action of axial force, the contact angle will increase.
The single row angular contact steel ball bearing can only withstand the axial load in one direction. When bearing the radial load, it will cause additional axial force. And it can only limit the axial displacement of the shaft or shell in one direction. The contact angle of the angular contact steel ball bearings is 40 degrees, so it can withstand a large axial load. The angular contact steel ball bearing is non-separate type of design, the shoulder height of the inner and outer varies. In order to improve the bearing capacity, one side of the shoulder will be processed lower so that the bearing can be put into more steel balls.
The double row angular contact steel ball bearing can withstand radial, axial joint loads and moment loads mainly consisting of larger radial loads, limiting the axial displacement of both axes. If there is a tilt angle between the inner and outer ring of the bearing, the bearing life will be affected, reducing the bearing operation accuracy and increasing the operation noise. The double row angular contact steel ball bearing generally uses the nylon cage or brass solid cage.
