Internal High Frequency Induction Hardened Pin Bushing

Our Premium Steel Bushings are engineered to deliver unbeatable performance in heavy-duty industrial applications, with the internal high-frequency bushing as a flagship product in our range of Steel Bushings.   Crafted from high-grade 45# or 40Cr steel, our High-Quality Bushings undergo a precision manufacturing process: the matrix is quenched and tempered for robust hardness, the inner surface is machined with spiral oil grooves, then treated with internal high-frequency induction hardening, and finished with a polymer coating for self-lubrication and protection.   These Durable Steel Bushings boast a matrix hardness of HB>240, a surface hardness of HRC52-58, and an optimized hardened layer depth of 0.8–1.2 mm, ensuring exceptional compressive strength, wear resistance, and durability under cyclic loads. For unique operational needs, we also offer Custom Steel Bushings tailored to your exact specifications. Backed by a high cost-performance ratio, our bushings provide long-lastin…
