956A1273G01 is a precision-manufactured aerospace engine low-pressure compressor (LPC) rotor spacer, compliant with AS9100D quality standards and FAA/EASA regulations, designed for large commercial turbofan engines. It is used between adjacent LPC disk components, maintaining a fixed axial distance between the disks, which is critical for ensuring the correct position of the LPC rotor blades, keeping the uniformity of the air flow path, and avoiding friction or collision between components during high-speed rotation.

Made from high-strength, heat-resistant and corrosion-resistant titanium alloy, it withstands operating temperatures up to 610°C and continuous centrifugal force. Weighing 0.72kg with a precision-machined positioning structure, it allows for fast installation and dimensional inspection during LPC MRO overhauls. FAA Part 25 certified, it is a key component for LPC operational stability.
