1. Product Characteristics        Fluid sealing is implemented by combining gliding sealing between the sealing ring and the shaft and interface sealing between the sealing ring and the case.         Axial abrasion can be compensated so that shaft is able to work continuously even when axial displacement is introduced by vibration and shock.         Aluminum is being used in the structure so that weight of the equipment is reduced and maintenance can also be done offshore.         No grease is required due to the feature of self-lubrication of the sealing ring.         Insulation has been used to avoid electrical corrosion between Aluminum and other metal parts.
