Internal High Frequency Induction Hardened Pin Shaft

Our Pin Shaft Series pairs seamlessly with premium internal high-frequency bushings to deliver unbeatable performance in heavy-duty applications. Crafted from 45# or 40Cr steel, our High-Quality Pin Shafts undergo a precision manufacturing process that includes quenching and tempering, ensuring a robust matrix hardness of HB>240 to withstand extreme compressive forces.   These Durable Pin Shafts are engineered to work in perfect harmony with our internal high-frequency bushings, which feature spiral oil grooves and a polymer coating for self-lubrication. The bushing’s surface hardness of HRC52-58 and hardened layer depth of 0.8–1.2 mm, combined with the pin shaft’s rugged construction, creates a system that delivers exceptional wear resistance and durability under cyclic loading.   Backed by a high cost-performance ratio, this pairing ensures reliable long-term operation, making our Pin Shaft Series an economical and dependable choice for industries ranging from construction to mat…
