Durable Nitrided Steel Bushing for Industrial Use

Our Steel Bushings are engineered to deliver exceptional performance in high-demand industrial environments, starting with a foundation of 40Cr or 42CrMo steel. These Premium Steel Bushings undergo quenching and tempering to achieve a stable core hardness of HB260-300, providing robust compressive strength to withstand heavy loads and prolonged use.   Their inner surfaces are precision-machined with spiral oil grooves, then treated with advanced QPQ salt bath nitriding to create a surface hardness exceeding HV0.1 600, a dense white layer over 15μm thick, and an effective hardening depth of 0.2–0.4mm. A final polymer coating enhances lubrication, reducing friction and minimizing wear.   As High-Quality Bushings, they offer outstanding wear and corrosion resistance, while the spiral grooves ensure efficient oil retention for lasting lubrication. These Durable Steel Bushings excel in high-stress, high-frequency operating conditions, extending service life and reducing maintenance. Whethe…
