Monton solutions for downhole drilling tools

Whether you’re drilling for oil or gas, drill strings must endure extreme operating conditions. Monton solutions for downhole drilling tools are designed to increase performance and reliability.

Cylindrical thrust bearings
To provide superior axial thrust load support for sealed motors, Monton’s cylindrical thrust bearings are manufactured to the highest quality standards. The contact surfaces between the rollers and the raceways, and the internal geometry are all controlled to extremely tight tolerances to improve performance compared to low-quality cylindrical thrust bearings available in the marketplace.

Tungsten carbide radial bearings
Specially designed to provide excellent radial load support for both sealed and mud motors, Monton tungsten carbide radial bearings are made using a unique microwave sintering process (resulting in 1 600 Vickers hardness) as compared to typical conventional sintering (with 1 000 Vickers hardness). This results in a high hardness of 92 HRa for excellent wear resistance and longer life.

Downhole sealing solutions
Monton has innovative seal designs and quality materials for downhole rotating seals exposed to high pressure. The Monton Teflathene seal incorporates a low-friction PTFE seal ring bonded to a rubber body. The all-rubber DM2 seal separates drifting mud from lubricants in oil-lubricated mud motor bearings. Bottom hole assembly (BHA) tools such as shocks and jars require seals to protect the tool hydraulics from the abrasive drill muds and cuttings in the hole. Measure-while-drilling (MWD) tools sometimes require high-temperature sealing solutions.Monton has developed a full line of field-proven seals to work in this demanding environment, including a seal capable of withstanding up to 315 °C (600 °F).

Mud stack thrust bearings
Mud bearings close to the drill string end have a major impact on productivity and reliability. In addition to severe axial and shock loads, these bearings are “lubricated” with highly abrasive mud, which for a bearing is the definition of an extreme operating condition. Monton’s mudstack bearings are optimized for our customers’ applications through rigorous finite element analysis and physical lab tests by testing the bearings with drilling mud circulating through them.
Monton mudstack bearings provide:
• Improved wear resistance
• Increased load-carrying capacity
• Optimized load distribution
• Increased robustness
• Improved reliability
• Customized design
