Optimized Performance

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.

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.

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.
