Durable Steel Bushings for Reliable Performance

Our Premium Steel Bushings are engineered to deliver uncompromising performance in the most demanding industrial applications. Crafted from high-grade 40Cr or 42CrMo steel, these Steel Bushings undergo a precision quenching and tempering process to ensure a robust substrate hardness of HB260-300, laying the foundation for exceptional durability.   The inner surface of these High-Quality Bushings features honeycomb-shaped oil storage pockets, which work in tandem with a post-machining QPQ salt-bath nitriding treatment to achieve a surface hardness exceeding HV0.1>600. A final polymer coating further reduces friction, creating a self-lubricating effect that minimizes wear and extends service life.   Designed for reliability, our Premium Steel Bushings offer outstanding mechanical performance, with a low friction coefficient and superior wear resistance. They provide 500-1000 hours of neutral salt spray resistance, delivering reliable corrosion protection for long-term use. With a har…
