Sell now Details about SC8UU SCV8UU Linear Motion Bearing A simple rule for troubleshooting bearing temperatures: No more than 180 degrees Fahrenheit (82 degrees Celsius) on the housing. The bearing outer ring can be up to 20°F (11°C) hotter than the housing. 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 excess grease to escape. If at all possible, locating bearings out of the immediate heat zones or providing provisions to reduce bearing heat are preferred means to achieve optimum bearing service life performance. This can be accomplished by insulation procedures to reduce radiant heat. Also, shaft heat flingers or cooling wheels coupled with heat resistant shaft materials can reduce bearing temperatures. The use of water or air cooled bearing units is another method to reduce bearing temperatures to a more manageable range. Though these steps incur higher installation costs, long term benefits may be gained by reducing lubrication and maintenance problems often encountered with high temperature bearing applications. When there is no way to avoid heat exposure, bearings can be specially modified to accommodate high temperature applications. Bearings having optional components materials, special internal radial clearances, high temperature lubricants and special heat treatments (if necessary) can operate successfully at very high temperatures, as shown.
