Extend Operating Limits

For more than 30 years, Waukesha Bearings has led the design and development of ceramic and polymer bearing technology. These advanced materials extend the operating limits of both fixed profile and tilting pad bearings and allow lubrication by process fluids such as water and other low-viscosity fluids.

Our bearing design experience combined with advanced materials expertise provides the foundation for some of our highest performing products.

Wide Materials Range

In addition to the traditional range of silicon carbide and polymer-lined thrust and journal bearings, Waukesha Bearings offers solid polymer technology, such as Hiperax® thrust bearings optimized for operation in water-lubricated applications, and tungsten carbide thrust bearings to handle increasingly high temperatures in electric submersible pumps (ESPs).

Waukesha Bearings advanced material options also include super-hard polycrystalline diamond (PCD) surfaces and, for oil-lubricated machines, aluminum tin (AlSn) bearings.

Backed by continued investment in research and development via dedicated test rigs, Waukesha’s advanced material bearings are ideal for challenging environments such as ESPs or subsea pumping where equipment reliability and optimized performance are critical.

Aluminum Tin

For oil-lubricated machines, aluminum tin (AlSn) bearings may provide drop-in replacement for babbitt bearings to increase both temperature and load
capability within the same envelope.

combination bearing with polymers

Polymer

Engineered polymers, available in polymer-lined or solid polymer components, have higher operating temperature capabilities than babbitt, are compatible with water or other low-viscosity lubricants, and can provide electrical insulation as well as resistance to chemical attack.

Ceramic / Cermet

Ceramic and ceramic-metallic composites further extend load and temperature capability. Given their superior strength and hardness, these materials are frequently used in process lubrication where films are very thin and/or contamination of the lubricant is possible.

PCD thrust bearing and collar

Polycrystalline Diamond

Man-made polycrystalline diamond (PCD) surfaces are a super-hard bearing material that can provide reliable operation in multiphase fluid or with relatively large amount of abrasives in the lubricant. PCD is known for its high thermal conductivity, low coefficient of friction, and high hardness and fracture toughness.
