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
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 design
enables the bearing to last significantly longer than previous
bearing designs.
About the redesign process
To significantly improve bearing performance and
reliability,engineers used proprietary 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 virtual test rig,
engineers were able to identify and correct the problem of cracked
rings and sheared balls – two common problems with these bearing
