Elastomer O-Ring Our seals are molded out of proprietary rubber.
These O-rings are 100% inspected for size, shape and
hardness before they are put into the rock bit.
Silver Plated BeCu Bushing and Thrust
Washer Every bushing is made
from the highest grade of beryllium copper alloy, heat treated
to exact specifications and machined to the closest tolerances
to guarantee long life in each bit segment.
Specially Formulated grease Our grease is a blend of grease that is
degassed to prevent pressure build up in the high heat
conditions that occur in the bit.
Pressure
compensator The diaphragm in
the grease reservoir transfers pressure from the drilling fluid
to the grease. This provides a steady supply of
lubrication to the bearing surfaces.
Hardmetal on
the Shirttail A generous
covering of the shirttail with hardmetal is applied to every
journal.
BRP Protection The weldment holding the Ball Retaining
Pin is protected by three tungsten carbide buttons. This
added protection provides an assurance that the balls will
remain in the cone and the cone will remain on the bit.
Stainless Steel Nozzle Retaining Rings Every bit
shipped by GT has stainless steel nozzle retaining rings.
These have proven to be stronger than the normal carbon
steel retaining rings used by other manufacturers.
Center Holes Additional
circulation can be obtained at the bottom of the hole by
putting a hole in the middle of the bit. This is standard
on all of our sealed bearing air circulation bits.
