I am trying to check the clearances of existing white metal bearings on a 2250 hp electric motor. Ambient temp. is around 86 degF (30degC) and normal operating temp of bearing is around 122 degF (50 degC). We have a check sheet for the technicians but nobody knows what is out of spec or in spec...
I am looking for information/equation to determine the recommended clearance for Journal bearings (plain bearings) relative to RPM, temperature, and shaft diameter. I know there is a guide but can't seem to locate it.
I work in a refinery that 'Roasts' ore. I am searching for a material that will cope with 2500 degF - 2700 degF temperature to use as our burner telltale tube. We had used 310 stainless steel but it could not cope with the constant high temperature. Can anyone recommend a material that we can...
