Constructed from premium forged alloy steel and subject to strict quenching and tempering heat treatment. It delivers outstanding fatigue resistance, high‑impact tolerance and good dimensional stability under continuous alternating vibration generated by frequent swing start‑stop operations of excavator. The flat working surface maintains stable performance even under long‑term exposure to high‑temperature hydraulic oil. It firmly holds the whole set of return springs in position and restricts the movement of piston‑shoe assembly. Effectively prevent shoe displacement, dislodgement and abnormal gap change inside the swing motor, greatly reducing risks of internal leakage, weak swing performance and swing drift, so as to extend the service interval of swing motor overhaul.
Manufactured by high‑precision CNC machining with flatness, plate thickness and mounting hole dimensions fully compliant with original component specifications. No manual grinding or modification is required during field replacement, achieving direct drop‑in interchangeability with original part. Uniform spring preload can be obtained after proper installation, avoiding partial over‑loading and early spring breakage caused by uneven stress distribution. It contributes to smooth swing action, reliable swing brake locking and reduces abnormal noise and jitter inside M5X130 swing motor, suitable for heavy‑duty repair and rebuild scenarios of Hitachi excavator swing motor.
