C . Angular Contact Ball Bearing Details
Product Features Precision Angular Contact Ball BearingsDue to their internal design, angular contact ball bearings can withstand high radial-axial loads and reach high speeds. They are asymmetrical for manufacturing reasons and can withstand unidirectional axial loads only. Angular bearings are usually mounted in a group of two or more opposed preloaded units with rigid or elastic spacers. Typically, the inner and outer raceways and balls are made of chrome steel. Where operating conditions are severe, bearings may have ceramic balls creating a hybrid bearing.
Applications "Angular contact bearing applications :
electric motors,Spindle,automotive applications, home appliances, industrial equipment."
