60221643 Cylinder Block Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The Sany 60221643 cylinder block is a core load-bearing and sealing component of the hydraulic system and engine of Sany construction machinery. It is specially designed for hydraulic cylinders and engine cylinders, providing a motion track for the piston and piston rod, and forming a sealed working space with the piston and cylinder head. It bears the functions of load-bearing, sealing, and high temperature and high pressure 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 cylinder block relies on professional manufacturing technology and strict quality control. It is made of high-quality 34CrNiMo6 alloy structural steel and undergoes precision casting, CNC machining, tempering and anti-corrosion coating treatment. It has precise dimensions and no burrs, a surface hardness of HRC36-40 and a tensile strength of 1100MPa. It has high temperature resistance, corrosion resistance and deformation resistance. It can withstand high temperature and high pressure gas and hydraulic media, solve the pain points of cylinder block wear, cracks and leakage, extend the service life of hydraulic system and engine, and is suitable for long-term harsh working conditions.
Adopting an integral structure, the cylinder cavity is precision honed to a roughness of Ra0.8μm to ensure smooth piston reciprocation. It has built-in cooling water channels and air channels to optimize temperature distribution, reduce thermal stress, and prevent thermal cracking. It is precisely matched to the installation position, making assembly convenient, compact in structure, and with sufficient rigidity. It takes into account both load-bearing performance and adaptability, and is suitable for high-pressure and high-temperature working conditions.
