60039405 Brake Spring Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

Sany 60039405 brake spring is a core elastic actuator in the braking system of Sany construction machinery. It is specially designed for brakes and clutches, and its core function is to provide stable elastic force to realize the reset of braking components, buffer and dampen shocks, and assist in the braking and release. 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 brake spring relies on professional manufacturing technology and strict quality control. It is made of high-quality 60Si2Mn alloy 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 HRC48-53, high elastic limit and excellent fatigue resistance. It can withstand repeated compression and reset loads for a long time with small elastic decay. It solves the pain points of spring deformation, breakage and corrosion, extends the service life of the braking system and is suitable for long-term harsh working conditions.
It adopts a spiral compression structure with uniform number of turns and precise pitch. Both ends are ground flat to fit the braking components, resulting in uniform force distribution, smooth and non-jamming reset, corrosion resistance and fatigue resistance, precise matching with the installation position, convenient assembly, and compact structure. It takes into account elasticity, stability and adaptability, ensuring smooth and reliable braking action.
