1. It has rolling sealed bearing structure. The cylinder rolling element isplaced within the groove

of roller cone, thus enlarging the journal size and ensuring a betterperformance of roller bit.

2. The secondary surface of thrust bearing of roller bit has been handledwith antifriction and

hardening treatment so as to decrease the frictional force of bit forprotecting its hardening


3. The roller bit uses new type lubricating grease which can bear the hightemperature of 250ºC

and boasts abrasion resistance.

4. The full rubber oil reservoir uses limitabledifferential pressure and can prevent drilling fluid

from entering lubricating system so as to provide qualified lubrication forbearing system

The wear

resistance of teeth is enhanced with premium tungsten carbide hardfacing onthe tooth surfaces

for steel tooth bit.
