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.
