Product Profile: Heavy-Duty Traveling Mechanism Shaft - Telescopic cylinder Shaft

A critical force-transmission component connecting telescopic cylinders to walking systems in excavators, cranes, pavers, and other construction machinery. Engineered to convert cylinder thrust/pull into precise linear motion while withstanding extreme operational stresses.

Key Features:
✔ High-Strength Material – 42CrMo/35CrMo alloy steel, quenched & tempered to 241-285 HBW
✔ Surface Optimization – Quenched to 45-55 HRC + chrome-plated (20-50μm) for wear/corrosion resistance
✔ Integrated Sealing Design – Boss structures for retaining/sealing rings to prevent axial movement and dust ingress
✔ Force Transmission – Efficiently transfers cylinder extension/retraction forces to traveling mechanisms
