3M™ Hydrodynamic Thrust Bearings are designed for demanding electrical submersible pumps (ESPs). The bearing faces are separated by a fluid film, which minimizes wear and significantly decreases bearing frictional losses.

Minimizing Wear and Frictional Losses
In electrical submersible pumps, thrust bearings are exposed to a number of challenging downhole conditions, including high shock loads, misalignment and abrasive lubrication. 3M™ Hydrodynamic Thrust Bearings are designed to minimize wear and frictional losses.

High Strength for Improved Performance
3M hydrodynamic thrust bearings are made from 3M™ Silicon Carbide, a high-strength technical ceramic with excellent resistance to high temperatures, corrosion and abrasion. The intrinsic strength of this material, coupled with patented spring mount technology, delivers outstanding shock absorption and high load capacity.

In addition, 3M technologies maximize load capacity by allowing pads to both tilt at an optimal angle and flex axially, equally distributing thrust load among pads.

The Power of Ceramics
Silicon carbide’s high abrasion resistance allows manufacturers to design process lubricated systems where environmental concerns restrict the use of lubrication. This same capability – when used in oil lubricated applications – increases equipment reliability in the event of seal failure.
