Angular contact ball bearings,Contact Angle Offered in 15, 25, 30 and 40 degree angles.Cages available in a range of Polyamide, steel and brass cage assemblies.This kind of ball bearing features a contact angle that makes them extremely suitable for simultaneous radial and axial loads. This contact angle is formed by a shift in the races of the inner and outer ring in relation to each other. There are different versions of angular contact bearings, such as open type and sealed type.In addition, there are single row and double row angular contact ball bearings.,These ball bearings are available in a large number of different versions and dimensions, specifically for axial loads and clearance-free precision applications.
