The conical clamping ring H 27078 is a precision-engineered securing component used in the Sulzer ASL25 engine to provide strong, vibration-resistant axial locking of critical assemblies. Its conical geometry generates uniform radial pressure during tightening, ensuring stable positioning and reliable retention of associated components under high mechanical loads and thermal cycling. Manufactured from high-strength material with accurate surface finish, this clamping ring minimizes micro-movement, reduces wear on mating parts, and contributes significantly to the long-term mechanical stability and operational reliability of the engine.
