Just about anywhere a bearing is used to support a rotating shaft, you will find a Rotating Shaft Seal installed to keep lubricating fluids in the system and contamination out.
Parker offers a wide variety of seal styles. There are literally hundreds of different styles. Most are variations of the standard configuration utilizing a rubber sealing lip to lightly contact a rotating shaft and a metal case to press fit into a stationary housing. Depending on the application, Rotary Shaft Seals can be supplied with or without a metal spring, a secondary wiping lip or auxiliary devices. The sealing lip can be bonded to a bare metal case or the case can be supplied covered with rubber.
