Roller Cone Bits: Motor Product Line
MOTOR Product Line (AU/VU/NU):
Motor bits are designed to have high performance and durability in a wide range of applications due to the use of high reliability bearing’s design, optimal cutting structure and advanced bit body protection system.
Motor bits can be equipped with single or double-sealed journal or roller bearings.
Motor bits are either steel tooth with special patented wear-resistant hardfacing on the teeth, or TCI.
The gauge can be protected with tungsten carbide inserts. For additional protection against gauge loss, a near gauge of tungsten carbide inserts can be used. For certain applications diamond compacts can be applied combined with TCI.
Shirttail and leg leading edge are hardfaced. Shirttail can be protected with tungsten carbide or diamond compacts or a combination of tungsten carbide and diamond compacts.
