The spherical cup, designated with code number H 27059, is a precision-engineered component used in the Adriadiesel/Jugoturbina/Zgoda/Sulzer ASL25 diesel engine. Designed to accommodate and support spherical motion within mechanical assemblies, this cup allows for controlled angular movement, reducing stress and wear on adjacent parts. It plays a crucial role in enhancing alignment and flexibility in high-load connections, such as within valve gear systems. Made from durable, wear-resistant materials, the spherical cup ensures smooth operation and contributes to the longevity and reliability of engine mechanisms.
