Hitachi ZAX330-5G 油圧ショベルのための涨紧总成 その他のサスペンションスペア部品

The track adjuster assembly (tension‑recoil assembly) is a heavy‑duty core undercarriage spare part for Hitachi large excavators. It is fully pre‑assembled, including grease‑fed tension cylinder, heavy‑load recoil buffer spring, piston rod, complete sealing kit, spring seat and grease nipple. It serves as a direct‑fit aftermarket replacement for the Hitachi ZAX330‑5G excavator.

Track tension is adjusted by injecting grease. The heavy‑duty recoil spring absorbs fierce impact and continuous vibration from rugged terrain, quarry and heavy‑load digging operations. It stabilises the idler position and maintains consistent track tightness to protect the whole heavy‑duty travel undercarriage system.
