M41 Long-Stack Mud Lubricated Bearing Assembly

M41 Mud Motor
The Future is Now

By lengthening bit-to-bend, our engineers have packed even more into our industry-leading mud lubricated motor design to give drillers more power—and more confidence—to deliver high torque and high ROP.

Key features
  • Lengthened bit-to-bend, fixed bend and adjustables
  • Greatly reduced side load on lower restrictor bearings
  • Increased weight-on-bit capacity
  • Longer, 3-part bearing stack compression system
  • Split ring mandrel catch, new spacers and crush ring system
  • Mandrel flex relief
  • Cold-rolled 30 deg round housing thread

Rotary Steerable System Motors

Optimize drilling efficiency, chase faster ROPs and drill confidently with motors specifically designed to get the most out of your Rotary Steerable System (RSS) technology—and ensure your RSS always returns safely.

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.
