Advanced Bearing Systems

As the demand for energy grows around the world, so do the demands put on the equipment operating in the oil & gas industry.  Depleting oil and natural gas reserves require higher performing rotating equipment that places extraordinary demands on rotor-bearing systems.

Fluid film bearings and magnetic bearing systems from Waukesha Bearings are used at almost every stage of oil and gas production – in pumps, compressors, turboexpanders and motors used in the extraction, refining, transport and storage of oil and natural gas. Advanced bearing features, material options and magnetic bearing technology all help drive performance to new levels, particularly in remote and subsea oil & gas applications.

Machine designers turn to Waukesha Bearings as they take their equipment to new levels of performance, reliability and availability.

Flexure Pivot journal bearing with ISFD technology

Leading Vibration Solutions

With our in-depth understanding of system rotordynamics, Waukesha Bearings offers proven solutions to improve stability and control vibrations. Chief among those solutions, our ISFD® technology provides highly engineered damping and stiffness to maximize energy dissipation at the bearing locations. Flexure Pivot tilt pads eliminate pivot wear and maintain tight tolerances to offer high stability without degradation in performance over time.

Case Study

Over a 13-year span, a major South American oil company’s maintenance department fought recurring high vibrations in three gas reinjection compressor trains. A thorough analysis of the compressors and an inspection of damaged components pointed to a two-part solution. Since the implementation, the compressors have exhibited low vibration levels and overall efficiency has increased.

canned magnetic bearings in a hermetically sealed motor compressor
Canned Magnetic Bearings Achieve 99.9% Availability & Zero Emissions

In 2002, a leading oil & gas customer approached Waukesha with the challenge of developing a bearing for a hermetically sealed integral motor compressor. Availability and reliability were the customer’s primary objectives. The end user could achieve a significant cap-ex savings in the installation if the motor compressor could be located outdoors, with no building or enclosure required.

Stability for Compressor Station Refrigeration Process

At a compression station in West Siberia, a refrigeration process applied to the gas at the plant outlet created a requirement for a highly efficiency compressor. That efficiency was achieved with a compressor rotor shaft with a high slenderness ratio, resulting in a very flexible shaft. The industry-leading processing power and advanced control algorithms of Waukesha magnetic bearing controllers were required to make these machines a success.
