The spiral seal bearing code H 81153 is engineered to offer advanced sealing performance in rotating or reciprocating engine parts of the ASL25 diesel engine. Its spiral geometry increases surface contact and resilience against pressure fluctuations and mechanical wear. This seal is especially suited for high-speed or high-temperature environments where traditional seals might degrade quickly. By maintaining fluid integrity and reducing the risk of leakage, the spiral seal contributes to longer engine lifespan and minimized maintenance needs.
