Taper roller bearing

  

Tapered roller bearings are a unique subset of axial roller bearings in which the rollers are tapered rather than straight right cylindrical. The roller shape allows thrust loads to be withstood in addition to the radial loads. A familiar application for tapered roller bearings is the central hub bearings for automobile wheels. When an auto traverses a turn, the wheels must withstand a significant lateral force, so that tapered roller bearings are necessary. 

 

 

Description of Tapered roller bearing: 

        Tapered roller bearings are separable, consisting of the inner ring with 

roller and cage assembly, can be mounted separately from the cup (outer ring). 

The modified contact line between rollers and raceway contacts reduce the 

stress concentration. Tapered roller bearings take large radial loads and axial loads.

 

     They only have axial loads for carrying capacity in one direction; therefore, another

one logarithmic tapered roller bearings should be mounted to support the opposite 

axial loads. The most consumed tapered roller bearings are single-row tapered roller 

bearings. In recent years, small sized double row tapered roller bearings has also been 

used in the cars front wheel hubs. And four-row tapered roller bearings are adopted in

large-size cold and hot rolling mills as well as other heavy machinery.
