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.
