Angular contact ball bearings have raceways in the inner and outer rings
 that are displaced relative to each other in the direction of the 
bearing axis. Single row angular contact ball bearings can accommodate 
axial loads in one direction only. This type of bearing is particularly 
suitable for carrying combined loads (radial and axial load) as well as 
pure axial loads and can be operated at relatively high speeds . WSBC 
can offer different contact angle of 15, 25,40 degree ,different 
materials Chrome steel, ceramic or hybrid and different cage assemblies 
Polyamide, steel and brass .This type of bearings are mainly used in 
machine spindle, gearbox, reducer and supercharger etc .If you want to
