Bearing seal
Apr 25, 2018

The seal of the slewing bearing is on the one hand to prevent the leakage of the grease that has been filled, and on the other hand it is to prevent external dust, impurities and moisture from invading the bearing and affecting its normal operation. Since the slewing bearing is mostly operated under heavy load and low speed, the seal type of the bearing adopts two structures, a rubber seal ring and a labyrinth seal. The rubber seal structure itself has a simple structure, small footprint, reliable sealing properties and has been widely used, but its shortcoming is that in the high temperature state, the rubber seal lip is easy to be aged and lose the sealability, so at the high temperature Labyrinth seals should be used for turntable bearings operating under working conditions.
