Product Description
The bearings in a mud motor at the end of a drilling 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: they bear heavy axial and shock loads and are exposed with 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 drilling 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, they are "lubricated" with highly abrasive mud, which, for a bearing, is the definition of an extreme operating condition.
How does the new bearing work?
The typical mud motor bearing contains 8 to 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 have been worn equally. Then, the load is shifted back to the first row and the process is repeated. This unique design enables the bearing to work significantly longer than previously designed bearings.
About the redesign process
To significantly improve bearing performance and reliability, our engineers use proprietary design and simulation tools to:
• accurately define the behaviour of a bearing stack;
• redesign the bearing to minimise stresses and optimise loading capacity;
• test new designs and materials.
Our engineers are able to recognise and solve the problems on cracked rings and shorn balls by meanse of the virtual test rig.
