Thrust Bearings for Electric Submersible Pumps

Waukesha Bearings offers a range of solutions to maximize bearing life and optimize bearing performance in electric submersible pumps (ESPs) – increasing the efficiency, production and operating life of your pump.

 


Bronze Deflection Pad Bearing

Bronze Bearings

For ESPs operating under low loads and for upthrust bearings, Waukesha Bearings offers a selection of bronze bearing designs. Fixed geometry designs include cast bronze, taperland and threaded OD thrust bearings, all of which eliminate pad flutter on the upthrust bearing.

The Waukesha Bearings Deflection Pad® thrust bearing (pictured) provides increased load capacity with a bronze bearing. Successful operational experience for the Deflection Pad bearing includes lubricating oil temperatures above 150°C (302°F) with unit loads of 2 MPa (290 psi) and higher.

 


Polymer Hidrax bearing for electric submersible pumps

Polymer Hidrax™ Bearings

Polymer-lined tilt pad thrust bearings like the Hidrax bearing from Waukesha Bearings are the standard for ESP operating temperatures up to 200°C (392°F) and loads up to 8 MPa (1160 psi). They are widely used in both the seal/protector section and the motor of ESPs.

The high temperature and load capabilities of the engineered polymer lining are complemented by the tilt pad design’s tolerance for misalignment and ability to accommodate a wide range of loads and speeds.

 


Hidrax HT thrust bearing for ESPs in SAGD applications

Ceramic Hidrax™ HT Bearings

For the higher temperatures in steam-assisted gravity drainage (SAGD) wells, Hidrax HT thrust bearings feature durable ceramic/cermet materials that retain their surface hardness and a load capacity of 8 MPa (1160 psi) at lubricating oil temperatures of 300°C (572°F) and higher.

Hidrax HT bearings use the well-proven Hidrax platform, making them ideal for drop-in replacement of existing polymer bearings as ESPs are updated with SAGD technology.
