ROLLER CONE BIT BEARING ASSEMBLY

 

Journal bearing bits do not have roller bearings.

 

The cones are mounted directly onto the journal.

 

This offers the advantage of a larger contact area over which the load is transmitted from the cone to the journal.

 

The contact area is specially treated and inlaid with alloys to increase wear resistance.

 

Only a small amount of lubrication is required as part of the sealing system.

 

Ball bearings are still used to retain the cones on the journal.
