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
