Power Generation

Performance and Reliability for the Power Grid – Today and Tomorrow

The power generation industry faces significant change as the world turns its attention to clean energy sources. New machine designs require expert rotordynamic analysis and robust bearings with verified performance. Meanwhile, traditional power gen facilities must continue to improve operational flexibility and address power-density requirements, environmental impact and fuel costs.

With our extensive application experience, expertise in rotor-bearing system optimization, and ongoing research & development, Waukesha Bearings delivers highly reliable, high-performing bearing solutions to meet the challenges of power generation, today and well into the future.

Tilt pad journal bearings

Journal Bearings

Waukesha Bearings custom engineers tilt pad and fixed profile journal bearings to specific operating conditions. Expert application of specialized design features ensures our bearings transfer radial loads with minimum power loss and optimum dynamic characteristics.

Tilt pad thrust bearings

Thrust Bearings

Waukesha Bearings offers fixed profile thrust bearings for lightly loaded applications, and advanced tilting pad solutions for more demanding operating conditions. Tilt pad designs may be non-equalizing or self-equalizing, and patented design features can address industry-wide challenges such as axial vibration.

Solid polymer thrust bearing in combination with polymer-lined journal bearing

Polymer Bearing Surfaces

High-performance polymer materials, combined with an optimized bearing design, can allow continuous operation under high loads and temperatures, low-viscosity fluids and adverse conditions. Polymer materials have operating temperature capabilities of up to 250°C (482°F), compared to 130°C (266°F) for babbitt.

Case Study

For a power generation customer in Scandinavia, Doosan Škoda Power engineered a 46 MW steam turbine as part of a combined cycle system. When high subsynchronous vibrations forced a trip in turbine operation at just 27 MW versus the rated 46 MW, the ISFD design provided rotordynamic stability needed to achieve full power output.
