Jacketed packing rings with code EN14U2429 are advanced sealing elements used in critical areas of the MAN L21/31 engine where high-performance sealing is required. Featuring a soft core (often graphite or PTFE) surrounded by a durable metal jacket, these rings combine flexibility with strength, adapting to surface imperfections while resisting extreme heat and pressure. They are commonly installed in exhaust, cylinder, or high-pressure sealing areas, ensuring leak-proof performance and long-term durability.
The complete damper end cover with code K 16500 is an integral part of the engine’s vibration dampening system, located at the far end of the crankshaft in the ZV40/48 engine. This component encloses the torsional damper mechanism, protecting it from mechanical damage and environmental exposure. Designed to withstand the effects of rotating mass forces, heat, and oil exposure, the cover ensures the proper functioning of the damper, which reduces engine vibration and mechanical stress. Its robust construction contributes to smoother engine operation and extends the life of connected rotating assemblies.
The ring coded K 27010 is a specially designed support and locking element used in combination with component K 27008 in the ZV40/48 engine assembly. It ensures secure positioning and mechanical stability of the mating part, particularly under dynamic engine conditions involving vibration, thermal expansion, or pressure fluctuations. Manufactured with tight tolerances and wear-resistant materials, this ring plays an important role in maintaining sealing integrity and axial alignment. Its durable construction helps extend the lifespan of the assembly and supports reliable engine operation in harsh industrial and marine environments.
The cover with code K 27007 is a vital protective component used in conjunction with the bearing casing K 28000 in the Sulzer ZV40/48 diesel engine. Its primary function is to shield the bearing assembly from external contaminants such as dust, oil mist, and moisture, while also helping to retain internal lubrication. Precision-machined from corrosion-resistant materials, this cover ensures long-term protection of the rotating elements, preserving the alignment and performance of the engine's drive train. By minimizing wear and preventing ingress of harmful particles, it contributes to smoother engine operation and reduced maintenance needs.
The snap ring coded K 27029 is a circular retaining element used to lock flange K 27026 in place within the ZV40/48 diesel engine structure. Designed to fit into a machined groove, it provides axial retention and prevents disassembly of connected parts due to pressure fluctuations or mechanical motion. This compact yet essential component is made from spring steel or similar resilient materials to ensure consistent clamping force and durability. Its proper function supports the secure fit and alignment of the starting valve assembly.
The nut with code K 27039 is a precision fastener designed specifically for securing stud K 11122 within the ZV40/48 diesel engine assembly. Built to resist vibration, high torque, and thermal cycling, it plays a critical role in maintaining mechanical stability across connected components such as covers, manifolds, or housings. Its precise threading and high-strength alloy composition ensure tight fastening without loosening during operation, contributing to engine safety and long-term reliability.
