Mud Lubricated Bearing Assemblies

Mud lubricated bearing assemblies are the choice of drillers looking for maximum operating torques and weight-on-bit loads, and those operating in extreme drilling conditions.

Thru Tubing Motors

While small in diameter, our thru tubing motor designs provide coiled tube drillers with the same Wenzel reliability, durability and performance as their larger downhole motor cousins.
