The buffer disc, identified by code number K 32309, plays a critical role in absorbing and distributing mechanical stresses between housing K 32301 and cover K 32315 in the Sulzer ZV40/48 engine. This component functions as a protective layer, preventing metal-to-metal contact and minimizing vibration and wear during engine operation. Its precise construction and material resilience are essential for maintaining structural integrity and extending the service life of both the housing and cover. As part of the engine’s mechanical damping system, the buffer disc is crucial for long-term stability and smooth performance under demanding industrial conditions.
