M35 Long-Stack Oil Sealed Bearing Assembly
M35 Long-Stack Oil Sealed Bearing Assembly
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
