ROLLER CONE BIT BEARING ASSEMBLY

 

There have been a number of developments in bearing technology used in rock bits :

 

The bearing assemblies of the first roller cone bits were open to the drilling fluid.

 

Sealed bearing bits were introduced in the late 1950s, to extend the bearing life of insert bits.

 

The sealing mechanism prevents abrasive solids in the mud from entering and causing excess frictional resistance in the bearings.

 

The bearings are lubricated by grease which is fed in from a reservoir as required.

 

Some manufacturers claim a 25% increase in bearing life by using this arrangement .
