Angular contact ball bearings


Angular contact ball bearings are suitable for applications which require high accuracy and good high-speed performance. This type of bearing is designed to carry a combined load.
 
Single-row angular contact ball bearings and matched pair angular contact ball bearings
The standard contact angles are 15 ,30 and 40 .
 
They are identified, respectively, by the supplementary codes "C", "A"(omitted) and "B". Bearings with a smaller contact angle are more suitable for applications involving high-speed rotation.
Those with a larger contact angle feature superior axial load resistance.
 
Angular contact ball bearings are often preloaded to enhance their rigidity and rotating performance.
 
For high-precision matched pair angular contact ball bearings of class 5 or higher, which are used in machine tools and other precision equipment, the standard preload is specified in three levels: light(L), medium(M), and heavy(H).
