The functioning of double lip oil seals is based on the principle of hydrodynamic lubrication. When a shaft rotates, the primary lip establishes a contact with the shaft surface, creating a micro-film of lubricant that facilitates smooth operation. This film reduces friction and wear, allowing the seal to maintain its integrity even under high-speed conditions. The secondary lip plays a crucial role in enhancing the sealing efficiency by reducing the chances of oil escaping and contaminants entering the sealed environment.
