M35 Mud Motor
Built to Last

Our oil sealed bearing assemblies are built for ease of use and maintenance, lower service costs and reliable performance in low-to-moderate temperature wells. The WZL M35 oil sealed drilling motor is our next generation offering, featuring a maximized OD, lengthened bearing stack and increased flow area.

  • Bearing packs are isolated from drilling fluid, guarding internal components from debris
  • Oil sealed design and carbide coated parts offer paramount corrosion resistance
  • More fluid directed to bit for enhanced hydraulic efficiency, bottom-hole cleaning, bit life and ROP
  • High weight-on-bit thrust bearing capacity
  • Configurable jetted piston housing ports for optimal bypass

Oil Sealed Bearing Assemblies

As the name suggests, oil sealed bearing assemblies separate moving parts from drilling fluid in a sealed oil-lubricated assembly. This design keeps cuttings and debris out of bearings to improve reliability and reduce service costs.
