60221641 Drive shaft Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The Sany 60221641 drive shaft is a core power transmission component of the Sany construction machinery transmission system. It is specifically designed for gearboxes, drive axles, and planetary transmission mechanisms. Its core function is to transmit engine power and drive equipment operation. It plays a crucial role in power connection and torsional load resistance. It is compatible with Sany and various mainstream construction machinery and is widely used in excavators, crawler cranes, loaders, and other models. It is suitable for harsh working conditions such as mining and infrastructure construction and is the preferred component for aftermarket maintenance, parts wholesale, and foreign trade export.
This drive shaft relies on professional shaft manufacturing technology and strict quality control. It is made of 40Cr high-quality alloy structural steel, which has high strength and excellent toughness. It is precision forged, CNC turned, tempered, surface hardened and rust-proofed. It has precise dimensions and no burrs, surface hardness of HRC52-58, tensile strength ≥980MPa, wear resistance and torsion resistance, and can stably transmit power. It solves the pain points of drive shaft deformation, wear, breakage and corrosion, extends the service life of the transmission system and is suitable for long-term harsh working conditions.
