This premium B450 upper bush is a critical wear‑resistant spare part for B450 hydraulic rock breaker. Produced from high‑quality alloy steel and processed with professional heat‑treatment technology, this upper bushing achieves high surface hardness, great wear resistance and strong impact‑bearing capacity to adapt to harsh working environments such as mine exploitation, rock quarrying and building demolition. Precision machining guarantees strict dimensional accuracy for seamless installation and perfect matching inside the hydraulic hammer. It effectively reduces friction between the piston and outer housing, prevents abnormal wear of core internal components, stabilizes hammer operation performance and extends the whole service life of your rock breaker. Every product goes through strict quality inspection prior to delivery. It serves as an ideal direct‑fit replacement for worn original upper bushing of B450 hydraulic breaker.
