60221636 Piston Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The Sany 60221636 piston is a core transmission and sealing component for hydraulic cylinders and engines in Sany engineering machinery. It is specifically designed for hydraulic cylinders and engine cylinders, and its core function is to transmit pressure and drive the movement of components. Together with the cylinder body and seals, it forms a sealed working chamber. It is compatible with Sany and various mainstream engineering 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 piston relies on professional piston manufacturing technology and strict quality control. It is made of high-quality 20CrMnTi alloy structural steel, which has high strength and excellent toughness. It is precision forged, CNC turned, carburized and quenched, and phosphated for corrosion protection. It has precise dimensions and no burrs, a surface hardness of HRC58-62, and a tensile strength of ≥835MPa. It is wear-resistant and deformation-resistant, and can stably transmit pressure. It solves the pain points of piston wear, sealing leakage, and jamming, extends the service life of hydraulic/power systems, and is suitable for long-term harsh working conditions.
