Standard Journal Bearing
Precision finished journal bearing with silver plated floating bushing and silver plated
thrustwasher for low cost applications.
Radial Seal - HNBR
Hydrogenated Nitrile Butadiene Rubber (HNBR) radial seal.
Silver-Plated Thrustwasher
A floating silver-plated stellite washer located between lug and cutter thrust bearing surfaces provides reduced operating temperatures and more consistent bearing performance.
MudPick II?Hydraulics
Patented nozzle design directing a sweeping fluid flow directly into the cutting path at the formation failure zone. The most aggressive hydraulic arrangement to maximize cleaning and ROP.
Low Cone Offset
Maximum durability cutting action for longer life
P (KPR) Premium Shirttail Protection
Protruding round top inserts for added wear resistance and improved stability without limiting annular flow area.
