Reliable Steel Bushings for Heavy Duty Use

Our Premium Steel Bushings excel in high-stakes industrial environments, where durability and precision are critical. Forged from 40Cr or 42CrMo steel, these Steel Bushings undergo rigorous quenching and tempering, ensuring a substrate hardness of HB260-300 for a robust foundation.   As High-Quality Bushings, they feature a precision-engineered inner surface with honeycomb oil storage pockets, paired with QPQ salt-bath nitriding to achieve a surface hardness of HV0.1>600. A final polymer coating delivers a self-lubricating effect, reducing friction and minimizing wear for longer service life.   These Premium Steel Bushings deliver exceptional mechanical performance: large oil storage capacity ensures efficient lubrication and low oil consumption, while a friction-reducing polymer coating and hardened surface deliver superior wear resistance. Backed by 500-1000 hours of neutral salt spray resistance, they provide long-lasting corrosion protection. With a hardened layer depth of 0.2–0…
