We test and re-test all of our components so that you can be assured of the most durable and highest-performing motors in the industry. Cobra Downhole Motors assigns and maintains serial numbers for every major component it builds. Traceability is documented and maintained at every step in the manufacturing and service process. Before we deliver a motor, every part is thoroughly inspected to ensure that it meets our precise specifications. In addition, we can provide rental, lease to purchase or purchase options with qualified training and 24/7 technical support.
Cobra MotorsEngineered for durability and longevity, Cobra drilling motors are designed and manufactured to the most stringent, specific tolerances and are made of the highest quality materials. The Cobra downhole motor is designed with the latest technology, utilizing “clean sheet” engineering. Our customers and their specific applications dictate our motor designs.
Power Sections and Flex-Coupling
TransmissionsOur field-proven power section designs provide the optimal combination of speed and torque delivered directly to the bit. Cobra has the right power section to meet the most demanding environments. Speed and torque delivered from the power section is transferred via a high strength flex-coupling transmission for maximum torque output and reliability. This is the highest rated transmission on the market. For more information on Cobra Downhole Motors’, please call us at 281 587-0005 or visit our web site at www.cobradownhole.com.

A three point geometrical model is used to determine a theoretical build rate potential of a given motor. Many factors (e.g. weight on bit, formation type, bit type, etc. affect the actual build rate achieved. Therefore these build rates should only be used as a guideline.
