Cougar Drilling Solutions

Drilling Motors


All parts of the bearing assembly have been designed to eliminate fatigue mechanisms by including large stress-relief radii manufactured from strong alloy steels. Our bearing assembly is designed to run not only with low torque/ high-speed power sections, but with the highest torque output power sections available on the market today.

The Cougar oil-sealed bearing assembly carries all the radial and thrust loads. To extend bearing life, Cougar uses a high-pressure rotary shaft seal design, specifically developed for drilling motor use. Abrasive drilling fluids never come in contact with the seal and will maintain oil lubrication on the bearings.

Seals for high temperature—450°F (230°C)—are also available. The sealing system also includes a unique flow-restrictor design to deliver maximum flow to the bit for exceptional hydraulic horsepower and hole cleaning.
