The 76.93 series of floating oil seals are developed for special assembly conditions and operating environments, with reverse seal ring designs.The floating oil seals of the 76.91 series are suitable for situations where a highly abrasive environment causes severe wear of the groove surface. The middle ring is divided into two structures, AB, and consists of a deep-drawn sheet ring wrapped in an oil-resistant rubber material. The outer surface of the rubber material has a wave shape, which not only ensures static sealing and transmission torque, but also prevents corrosion.
