Robust Steel Bushings for Industrial Machinery Use

Our Premium Steel Bushings excel in high-stakes industrial environments, where extreme durability and precise performance are critical. Forged from premium 40Cr or 42CrMo steel, these Steel Bushings undergo rigorous quenching and tempering, ensuring stable HB260-300 substrate hardness for a robust structural foundation.   As High-Quality Bushings, they feature a precision-machined inner surface with honeycomb oil pockets, paired with QPQ salt-bath nitriding for reliable HV0.1>600 surface hardness. A smooth polymer coating delivers effective self-lubrication, reducing friction and wear for extended service life.   These Premium Steel Bushings boast exceptional mechanical performance: large oil storage ensures efficient lubrication and low consumption, with superior wear resistance from the polymer coating and hardened surface. Backed by 500-1000 hours of neutral salt spray resistance for lasting corrosion protection, 0.2–0.4mm hardened layer and 15µm+ white layer, our Steel Bushings…
