High Precision 7050 Aluminum Aviation Bushing

Thermal‑Cycle Stabilized 5‑Axis CNC‑Machined 7050 Aluminum Bushing for Aircraft Control‑Surface Hinge‑Pin Housings Product Overview Aerospace hinge‑system integrators regularly face fit‑degradation risks for high‑precision aluminum bushings under wide‑range airborne temperature cycling. Alternating cold high‑altitude cruise and ground‑level heating creates repeated thermal expansion‑contraction cycles. If inner and outer dimensional stability cannot hold tight tolerance, clearance drift occurs between bushing, hinge pin and mounting housing. Excessive clearance generates hinge‑play, amplifies control‑surface flutter tendency and increases routine hinge‑system adjustment workload during aircraft maintenance。This 7050 Aluminum Aviation Bushing delivers thermally‑stable hinge‑housing performance for secondary aircraft control‑surface hinge‑pin connecting assemblies. Manufactured from AMS‑qualified 7050‑T7451 stretch‑relieved aluminum forging with outer dimensions 50 × 50 × 150 mm and st…
