Angular Contact Ball Bearing 71902C

 71902C Angular Contact Ball Bearings

Contact angles: C-15°, AC-25°,  B-40°

Cage materials: brass,synthetic resin, molded polyamide resin.

Angular contact ball bearings are the most repesentive of the rolling bearings,a wide range of uses.for speed operation,but also very durable,without regular maintenance.small coefficient of friction of such bearings  ,limte high-speed,simple structure,low mannufactringcost and easy to reach a higher mannufacturing precision.

Size of the scope and diverse forms,applicatons in precision instrucments,low noise motors,automobiles,motocycles and general manchinery industries,mechanical industries are the most widely used one type of bearing.The main radial load to bear,it can withstand certainamount of axial load.  

Double direction thrust angular contact ball bearing

is the precision bearing which special design for the main axial of the machinery equipment,it can afford the loading of axial from two directions,if you compare with 511 series' thrust ball bearing the diameter of the steelball inside the bearings is samller,morequantity and they have 60° degree touching angle,so it will be more better for the high speed rotation.
