ROLLER CONE BIT BEARING ASSEMBLY

 

The cones of a roller cone bit are mounted on journals. There are three types of bearings used in these bits:

 

1. Roller bearings, which form the outer assembly and help to support the radial loading (or WOB)

 

2. Ball bearings, which resist longitudinal or thrust loads and also help to secure the cones on the journals

 

3. A friction bearing, in the nose assembly which helps to support the radial loading. The friction bearing consists of a special bushing pressed into the nose of the cone. This combines with the pilot pin on the journal to produce a low coefficient of friction to resist seizure and wear.
