Oil seal service life -
- In addition to sealing, thick rubber gaskets also provide cushioning and insulation properties. The flexible nature of rubber allows it to conform to irregular surfaces, providing a tight and secure seal. This is particularly important in applications where there may be movement or vibration, as the gasket can absorb shocks and prevent damage to the surrounding components.
Oil seals have a flexible lip that actually rubs against the rotating shaft or housing to prevent leakage. The spring keeps the lip in contact with the shaft. Bearing isolator oil seals are dynamic seals that incorporate a rotor or rotating member and a stator or stationary member. The rotor actually turns with the shaft. Some oil shafts are bearing isolators with a labyrinth construction. Others incorporate simpler O-rings.
