Product Description
Angular contact ball bearings have raceways on the inner and outer rings, and the inner and outer rings can be relatively displaced along the bearing axis.This type of bearing is particularly suitable for bearing compound loads, that is, loads acting both radially and axially. The axial load bearing capacity of angular contact ball bearings increases with the increase of the contact angle α.
Single row angular contact ball bearings can only bear axial load in one direction. When bearing radial load, additional axial force will be caused. And it can only li mit the axial displacement of the shaft or housing in one direction. Angular contact ball bearings have a contact angle of 40 degrees, so they can withstand large axial loads. Angular contact ball bearings are of non-separable design, and the shoulders on both sides of the inner and outer rings are different in height.
Double row angular contact ball bearings can withstand large radial loads, mainly combined radial and axial loads and moment loads, limiting the axial displacement of the shaft on both sides. The tiltability between the inner and outer rings of the double row angular contact ball bearing is mainly used to limit the bidirectional axial displacement of the shaft and the housing. The allowable tilt angle depends on the internal clearance of the bearing, bearing size, internal design and acting on it. The force and moment on the bearing, and the maximum allowable inclination angle should ensure that no excessive additional stress is generated in the bearing. If there is an inclination angle between the inner and outer rings of the bearing, it will affect the life of the bearing, and at the same time cause the bearing's running accuracy to decrease and the running noise to increase. Double row angular contact ball bearings generally use nylon cages or brass solid cages.

A wide range of applications:

• agriculture and forestry equipment
• automotive and industrial gearboxes
• automotive and truck electric components, such as alternators
• electric motors
• fluid machinery
• material handling
• power tools and household appliances
• textile machinery
• two Wheeler.
