How to Protect Bearings from the Elements

21/8/2020· Stand the bearing off the equipment to create a gap between the end of the equipment and the bearing housing, and install a sfing box and packing at the housing interface. This approach usually leads to scoring on the shaft in materials-handling equipment; therefore, it is best to install a surface-hardened, replaceable sleeve for the packing to run against.
