The running temperature for a bearing assembly depends on many factors such as speed,
bearing loads, ambient air temperature, and condition of bearings. Temperatures higher than
the human hand can tolerate are very satisfactory for good bearing operation and should not
cause alarm.
For a given speed and loading, the bearing housing temperature will stabilize at some
temperature, usually below 93°C | 200ºF, which will be the normal temperature for that
installation. Higher temperatures than this normal temperature, without any change in speed or
loading, can mean a lubrication difficulty or the approach of a bearing failure.
