Product Description
Angular contact ball bearings can withstand both radial and axial loads simultaneously. Can work at higher speeds. The larger the contact angle, the higher the axial load-bearing capacity. The contact angle is the angle between the line connecting the contact point between the ball and the raceway in the radial plane and the perpendicular line of the bearing axis. High precision and high-speed bearings typically have a contact angle of 15 degrees. Under the action of axial force, the contact angle will increase.
Single row angular contact ball bearing
Single row angular contact ball bearings can only withstand axial loads in one direction, and when subjected to radial loads, it will cause additional axial forces. And it can only limit the axial displacement of the shaft or housing in one direction. The contact angle of angular contact ball bearings is 40 degrees, so they can withstand large axial loads. Angular contact ball bearings are non separable designs, with varying heights of shoulders on both sides of the inner and outer rings. In order to improve the load capacity of the bearing, one side of the shoulder will be machined lower, allowing the bearing to fit more steel balls.
Double row angular contact ball bearing
Double row angular contact ball bearings can withstand large radial loads, mainly combined radial and axial loads, as well as torque loads, limiting the axial displacement of both sides of the shaft. The tilting ability between the inner and outer rings of double row angular contact ball bearings, which are mainly used to limit the bidirectional axial displacement of the shaft and housing, is limited. The allowable tilting angle depends on the internal clearance, bearing size, internal design, and the forces and moments acting on the bearing. The maximum allowable tilting angle should ensure that no excessive additional stress is generated inside the bearing. If there is a tilt angle between the inner and outer rings of the bearing, it will affect the service life of the bearing, and cause a decrease in the operating accuracy of the bearing and an increase in operating noise. Use nylon or brass solid retainers.
