TAPERED ROLLER BEARING MOUNTING

● Mounting

   Tapered roller bearings are designed to take both radial and thrust loading. Under radial loads, a force is generated in the axial

   direction that must be counteracted. As a result, tapered roller bearings arenormally adjusted against a second bearing. They 

   can be mounted in either a direct or indirect mounting arrangement shown in fig. 1. For applications where a direct mounting 

   arrangement is used and the outer ring is used to adjust the bearing setting, the outer ring is usually set in position by an 

   outer-ring follower or mounted in an outer-ring carrier. See fig. 2.

   For indirect mountings, bearing setting is typically achieved by clamping against one of the innerrings. Various designs, 

   including locknuts, stakenuts and end plates as shown in fig. 3 can be used.For applications requiring precision-class 

   bearings, a special precision nut can be used.
