Lubrication Mud Motor Bearings , Mudstack Thrust Bearings For
Downhole Drilling Tools
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).
Mudstack 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
Product Description
The bearings in a mud motor at the end of a drill string would
place a huge influence on productivity and reliability in terms of
oil drilling or gas drilling.The working condition of these mud
motor bearings are extremely harsh: the bearings bear heavy axial
and
shock loads, and they are also exposedwith highly abrasive mud.
• Special steel for all bearing components
• Full complement bearing
• Precision matched rings
• Unique bearing design to support heavy
• axial drilling loads
Application:
Oil drilling motor
Downhole motor
Electric submersible pump
Bearing life:
200hours
Main Customers:
Oil company like:SLB,Halliburton or GE
Main application:
Downhole motor or drilling motor
Down hole motor or drilling motor for the oil drilling industry
Bearing Assembly of Downhole Motor is used to transmit motor rotary
dynamic force to the bit, meanwhile to withstand axial and radial
load from drilling weight. Inside of the Bearing Assembly,Monton
uses TC Radial Bearing and a stacked thrust bearings. The thrust
bearings support the downward force resulting from the “weight on
bit” (WOB) and the loads from the combination of hydraulic thrust
and weight loads from internal components.Monton provides different
bearing assemblies, designed to meet the diverse requirements of
the drilling industry.
Downhole drilling motor bearings
Whether you’re drilling for oil or gas, the bearings in a mud motor
at the end of a drill string have a direct impact on productivity
and reliability.These mud motor bearings have to endure extreme
operating conditions. 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.
How the new bearing works ?
The typical mud motor bearing contains between 8 and 12 rows for
design optimization. When the bearing is new, the majority of the
load is accommodated by the first four or five rows. As each row
starts to wear, the load is shifted to the next row and the next
until all the rows are worn equally. Then, the load is shifted back
to the first row and the process is repeated. This unique Monton
design enables the bearing to last significantly longer than
previous bearing designs.
About the redesign process
To significantly improve bearing performance and reliability,Monton
engineers used proprietary Monton design and simulation tools to
• accurately define the behaviour of a bearing stack
• redesign the bearing to minimize stresses and optimise load
carrying capacity
• test new designs and materials. With the Monton virtual test rig,
engineers were able to identify and correct the problem of cracked
rings and sheared balls – two common problems with these bearing
