Standard springs are made of carbon steel. We use stainless-steel springs for our GR and GRST oil seals made from FKM rubber. In some rare cases, an O-ring is even used as a spring element. Standard PTFE lip seals are not fitted with springs.
The first step in installing oil seals is to clean the surface where they will be placed. Dirt, debris, and other contaminants can cause the oil seal to become damaged or misshapen, leading to leaks. Clean the surface with a solvent or soap and water, and make sure it is completely dry before installing the oil seal.
JTEKT provides special seals for use in a wide variety of machines and applications.
Table 5 lists the major special seals, their shapes, and their features.
