Oil seals

Listing ID #4074975

The Rotary Shaft Seal is  used for excluding dirt, dust, water or other particles, while retaining lubricant in rotary shaft equipment. It was developed as a means of protecting bearings of rotating shafts. The area between the sealing edge and the shaft is most important. The sealing effect is achieved by preloading the sealing lip making its internal diameter slightly smaller than the shaft diameter.  The garter spring ensures constant force to the shaft, flattening the sealing edge to a defined width.

Oil seals prevent internal system fluids from leaking and keep external contamination from entering the system. Leakage and/ or contaminants paths occur between the shaft and the seal lip and between the seal and the housing. Oil seals need to seal both dynamically (on the shaft) and statically (on the outer diameter of the seal).
