The sliding sleeve N 73118 is a precision-machined guiding component used in the Sulzer ASL25 engine to enable controlled axial movement and reliable alignment between interacting mechanical parts. Designed to operate under continuous mechanical load, vibration, and varying thermal conditions, this sleeve provides a smooth sliding interface that reduces friction and wear. Manufactured from high-quality, wear-resistant material, it ensures stable operation of the associated mechanism and maintains dimensional accuracy over long service intervals. By supporting smooth motion and protecting adjacent components from excessive stress, the N 73118 sliding sleeve contributes significantly to the reliability and durability of the engine’s mechanical assemblies.
