Advanced Pin Shaft Joining Methods

Our Pin Shaft Series showcases the pinnacle of heavy-duty engineering, offering high-quality pin shafts designed to excel in the most rigorous industrial applications.   Each of our durable pin shafts starts with premium 45# steel or 40Cr steel, which undergoes a dual heat treatment process: the substrate is quenched and tempered to a hardness of HB280–320, followed by medium-frequency induction hardening to achieve a surface hardness of HRC58–62, with an effective hardened layer depth of 2–4 mm. After precision finish machining, a specialized welding process ensures structural integrity, while customizable anti-rust coatings provide 500–1,000 hours of neutral salt spray resistance.   These high-quality pin shafts deliver exceptional mechanical performance, featuring high compressive strength and wear resistance to handle heavy loads and frequent movement in excavators and construction machinery. Whether for OEM replacements or custom projects, our durable pin shafts provide reliable,…
