Product Description

XSY Angular contact ball bearings are compose of inner and outer races, ball complement and bearing cage; however, different to other ball bearings like a deep groove ball bearing, an angular contact ball bearing is designed with axially asymmetric race.
 
As a result, angular contact ball bearings are more suitable for supporting "combined loads" (loading in both the radial and axial directions); pure axial-load supporting in one direction is also possible. Generally speaking, the supporting capability for an axial load; and at the same time, the smaller the supporting capability for a radial load.
 
According to  angular contact ball bearings manufacturers, single-row, and double-row  angular contact ball bearings are both popular ones in the market. A single row  angular contact ball bearings is suitable for carrying axial-load acting in one direction only; as a result, they are usually used in pairs or multi-arrangement in many applications. A double row  angular contact ball bearing, however, is suitable for both an axial-load and a radial-load in both directions.
 

Application: 
Single row  angular contact ball bearings are usually used in machine tool spindles, high frequency motors, gas turines, centrifugal separators, front hub of mini vehicles, differential pinions, etc.
 
Double row  angular contact ball bearings are extensively used in oil pumps, roots blowers, air compressors, various transmissions, printing machines and fuel injection bumps, and more.
