SKF provides tips ontroubleshooting bearing temperatures

A better procedurefor "hot"bearingswould be: Check the housing surface temperature. It might be OK, even though most people find anything over 130°F (55°C) toohotto touch. Slowly add the proper amount of fresh grease to the application (use SKF Dialset). If it's a motor or other machine with a grease relief, open the relief and allow ...
