Bearing Considerations for High-Temperature Applications

WebMaximum operating temperature for Babbitt is 300º F. In motors 180º F to 190º F is considered running hot. Some turbine applications run as high as 225° F. Many technicians however, will set the alarm at 185º F and trip at 205º F. Melting temperature for common Babbitt varies from 350º F to 475º F WebMar 15, 2024 · While this process prepares your bearings for extreme heat, lower steel hardness does increase the potential for increased wear at higher speeds. Proper load support is also critical. Higher operating temperatures support lower loads, so it can be valuable to identify and use a material that features a higher natural temperature range. WebJun 10, 2024 · The film thickness has to be sufficient at the actual operating temperature to separate the metal surfaces and support the bearing loads. Since oil viscosity decreases with increased temperatures, the initial film thickness has to be thicker at startup to allow for this decrease in viscosity. tatouage visage minimaliste
