The ball cap, designated by code number H 27051, is a precision-engineered component within the Adriadiesel/Jugoturbina/Zgoda/Sulzer ASL25 diesel engine. Its primary role is to provide a stable housing or support for ball joints or spherical elements in the mechanical system, ensuring smooth pivoting movements under load. Made from high-strength materials to resist wear and deformation, the ball cap is essential for maintaining alignment and reducing friction in the engine’s dynamic components. Its reliability directly contributes to the overall efficiency and lifespan of the machine.
