7321C (36321) Angular contact ball bearing is offered by Hahong International Trade (Shanghai) Co., Ltd.

1. Introduction.

An angular contact ball bearing uses axially asymmetric races. An axial load passes in a straight line through the bearing, whereas a radial load takes an oblique path that tends to want to separate the races axially. So the angle of contact on the inner race is the same as that on the outer race. Angular contact bearings better support "combined loads" (loading in both the radial and axial directions) and the contact angle of the bearing should be matched to the relative proportions of each. The larger the contact angle (typically in the range 10 to 45 degrees), the higher the axial load supported, but the lower the radial load. In high speed applications, such as turbines, jet engines, and dentistry equipment, the centrifugal forces generated by the balls changes the contact angle at the inner and outer race. Ceramics such as silicon nitride are now regularly used in such applications due to their low density (40% of steel). These materials significantly reduce centrifugal force and function well in high temperature environments. They also tend to wear similarly way to bearing steel—rather than cracking or shattering like glass or porcelain.

Most bicycles use angular-contact bearings in the headsets because the forces on these bearings are in both the radial and axial direction.

2. Design Attributes.

1). Specific geometry of angular contact bearing raceways and shoulders creates ball contact angles that support higher axial loads.

2). Expanded options include special lubricants, cage materials, preloads and coatings for additional corrosion resistance.

3. Applications.

Angular contact ball bearings are designed for combination radial and axial loading. They’re used in high-speed, high precision applications for:

1). Agriculture

2). Chemical

3). General industry

4). Utilities

4. Specifications.
