60221644 Spring plate Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The Sany 60221644 leaf spring is a core elastic load-bearing component in the suspension and braking systems of Sany construction machinery. It is specifically designed for equipment suspension and brake support parts. Its core function is to buffer road impacts and absorb vibrations, while also transmitting loads and guiding the movement trajectory of components. It plays a key role in buffering, bearing, and guiding. 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 leaf spring relies on professional leaf spring manufacturing technology and strict quality control. It is made of high-quality 65Mn spring steel and undergoes precision rolling, quenching and tempering, shot peening and anti-corrosion treatment. It has precise dimensions and no burrs, a surface hardness of HRC45-50, high elastic limit and excellent fatigue resistance. It can withstand repeated expansion and contraction deformation and load impact for a long time, effectively solving the pain points of leaf spring breakage, deformation, corrosion and elasticity decay, extending the overall service life of suspension and braking system, and is suitable for long-term use in harsh working conditions.
