The ball cap H 27050 is a precision-machined seating component used in the valve train and mechanical linkage assemblies of the Sulzer ASL25 engine. Designed to provide accurate load transfer and controlled articulation at spherical contact points, this ball cap ensures smooth motion and reliable force distribution under continuous dynamic loading. Its robust construction and finely finished contact surfaces minimize friction and localized wear, helping maintain precise alignment, reduce mechanical stress, and support long-term reliability of critical valve and control mechanisms.
