Heavy Duly Bellow Seal

STS-45 seals are equivalent to John crane type 502 & type 2100. The positive static seal between the bellows and the shaft, along with the free movement of the bellows, means that there is no sliding action that could lead to shaft damage by fretting. This ensures that the seal will automatically compesate for normal shaft runout and axial movements. These versatile seal can be used on a wide range of equipment.
