The pressure rod H 27216 is a high-strength mechanical transmission component used in the valve actuation system of the Sulzer ASL25 engine, transferring motion from the camshaft mechanism to the valve assembly. Manufactured for exceptional rigidity, straightness, and surface durability, the pressure rod ensures accurate motion control and consistent valve operation under extreme cyclic loading. By maintaining precise geometry and minimizing deflection, H 27216 helps preserve correct valve timing, reduce vibration, and support the overall efficiency and durability of the engine’s valve train system.
