60221630 Support ring Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The Sany 60221630 support ring is a core support and guide component in the hydraulic system and transmission mechanism of Sany construction machinery. It is specifically designed for the connection points of hydraulic cylinders, pistons, and shaft components. Its core function is to position and support components, guide their movement trajectory, and prevent component misalignment and wear. It also assists in sealing and blocking impurities, playing a crucial role in support, positioning, guidance, and protection. 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 support ring relies on professional sealing support manufacturing technology and strict quality control. It is made of PTFE Teflon and bronze powder composite material. Bronze powder is added to the Teflon masterbatch to enhance wear resistance. It has excellent oil resistance, aging resistance and corrosion resistance. It is precision injection molded, vacuum vulcanized and precision ground. It has accurate dimensions and no burrs. It has a Shore hardness of 70-75HA, tensile strength ≥18MPa and good self-lubricating properties. It can effectively support positioning components, reduce friction loss and solve the pain points of support ring wear, deformation, loosening and jamming. It avoids wear of shaft and piston components, extends the overall service life of hydraulic and transmission systems and is suitable for long-term harsh working conditions.
