The thrust ring K 71034 is a supporting component designed to work in conjunction with screw K 71033 in the Sulzer ZV40/48 engine’s pump assembly. Its function is to distribute axial loads evenly and provide a stable bearing surface for the fastening element during operation. By reducing localized stress and preventing direct metal-to-metal contact between critical parts, it minimizes wear and enhances the durability of the assembly. Engineered for high load capacity and resistance to deformation, the thrust ring maintains its dimensional stability under continuous mechanical stress and temperature variation. Its role is essential in ensuring the long-term reliability and smooth operation of the pump system.
