Advanced Material Options
As machine loads, speeds and temperatures increase, the main limitation for a bearing is frequently the bearing’s surface temperature. Typical industry practice is to limit the maximum operating temperature of babbitt bearings to 130°C (266°F) because babbitt loses strength at elevated temperatures.
Babbitt also has a relatively low fatigue strength compared to advanced materials. In extreme cases of dynamic loading, low fatigue strength can result in premature bearing damage.
Alternative fluid film bearing materials are available to accommodate more challenging operating conditions.
