Thrust angular contact ball bearings for oil drilling









Downhole drilling motor bearings



Whether youre 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

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
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, Montonuses 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.Montonprovides different bearing assemblies, designed to meet the diverse requirements of the drilling industry.
