956A1200G02 is a precision-manufactured aerospace engine low-pressure compressor (LPC) rotor balance weight, compliant with AS9100D quality standards and FAA/EASA regulations, designed for CFM56 series turbofan engines. It is installed on the LPC rotor to adjust the rotor's mass distribution, eliminating dynamic imbalance that would cause excessive vibration during high-speed rotation, which is critical for reducing wear of LPC bearings and related components, avoiding structural fatigue damage, and ensuring the stable operation of the entire engine.

Made from high-density tungsten-nickel alloy, it has a high mass-to-volume ratio to save installation space. Weighing 0.2kg with a precision-threaded mounting structure, it allows for fast adjustment and balance verification during LPC MRO overhauls. FAA Part 25 certified, it is a key component for LPC operational stability.
