Taper roller bearing 8520CD are designed to carry both thrust and radial loads and consist of four components: the cone, or inner ring; the cup, or outer ring; the tapered rollers, or rolling elements; and the cage, or roller retainer. the capacity of axial load carrying depends on the contact angle of outer ring's raceway. the bigger the contact angle is, the greater the capacity will be.
 
Taper Roller Bearing 8520CD Advantage:

1: Suitable for the radial and axial loaded.                                                                                 
2: with low wear rate and long life service.                                                                               
3: Can be used over a large temperature range.                                                                       
4: Allows maintenance free and long life operation.                                                                   
5: Suitable for dirty corrosion impact load and edge loading.                                                      
6: the base material provided a good shock absorbing capacity.                                                
7: with low and smoothly coefficient of friction and without stick slip effects
