At Waukesha Bearings, we collaborate with customers to engineer hydrodynamic fluid film bearings for optimized performance in individual operating conditions.
In addition to properly sizing bearings to handle the required loads and minimize power loss, we expertly apply surface geometries, tilt pad designs, lubrication methods, materials and other specialized features to achieve peak performance. The result is an endless variety of customized fixed profile and tilt pad bearing systems.
No matter how challenging the turbomachinery, our engineers have the knowledge and application experience to design the right solution.
Journal (Radial) Bearings
With fixed profile and tilt pads designs, and options such as hydrostatic jacking, ‘Directed Lubrication’ and combined thrust capability, Waukesha Bearings has journal bearing solutions for turbomachinery large and small.
Thrust (Axial) Bearings
From fixed profile designs for lightly loaded applications to advanced tilting pad configurations for high loads and speeds, Waukesha Bearings delivers optimized thrust bearing solutions.
Proven Waukesha Bearings vertical assembly designs range from large combination thrust and journal bearings for motor-driven reactor coolant pumps, to small, self-contained air-cooled units for LNG pumps.
Waukesha Bearings horizontal bearing assemblies include highly customized journal or combined journal and thrust bearings designed to interface with an external pressurized oil system or operate as a fully self-contained unit.
Comprehensive Rotordynamic Analysis
Through rotor modeling and a full evaluation of equipment operating conditions, Waukesha Bearings can simulate critical speeds, rotor modes, undamped natural frequency and unbalance response, among other characteristics.
Rotordynamic analysis tools are combined with bearing coefficients from in-house design programs to provide highly accurate analyses and predictions for the validation of original builds and the design of optimized solutions.
Engineered Damping for Vibration Control
Rotating equipment requires damping to control vibrations and prevent them from damaging the rotor, bearings and other components. While fluid film bearings provide a significant amount of damping, it may not be sufficient, particularly for machinery running at high speeds and/or with a flexible rotor. The system may require an increase in “effective” damping.
Waukesha Bearings ISFD® technology provides highly engineered damping and stiffness to shift critical speeds and increase the dynamic stability of the rotor/bearing system.
Advanced Materials for Advanced Performance
Materials play a significant role in bearing performance, and continuing materials development has expanded the ability to meet stringent application goals, such as increased load capacity, reduced power loss, or operation in process fluids.
Waukesha Bearings applies advanced materials, including polymers, ceramics, cermets and aluminum tin, to extend the operating limits of fixed profile and tilting pad bearings.

How Fluid Film Bearings Work
When properly designed and maintained, the working life of a fluid film bearing is theoretically infinite. Under these circumstances, contact between bearing surfaces and the rotor occurs only at start-up and in the final stages of rundown. During operation, the rotor moves on a continuous film of oil, water or other filtered process fluid.
