This product is an original equipment manufacturer (OEM) accessory, precisely matched to the cabs of SANY SY55/65/75/135/215/365 excavators and SCC750 crawler cranes, pump trucks, etc. Utilizing precision cutting and heat treatment processes, it is compatible with original installation positions and connecting components, allowing for quick installation without adjustment. It withstands on-site bumps, high and low temperatures, and dusty working conditions, rotating smoothly without jamming, and is wear-resistant and not easily deformed. It conforms to QJ/GAC 1240.062-2020 standard and complies with relevant specifications of JB/T 8409-2010 and GB 11567-2017.
This product is made of original factory-customized 45# high-quality carbon structural steel, which has been tempered and heat-treated. It has excellent comprehensive mechanical properties, strong impact resistance and fatigue resistance, and can stably transmit torque and withstand heavy loads. The surface is chrome-plated for corrosion protection, rust prevention, aging resistance and wear resistance. Precision machining ensures coaxiality, making it suitable for complex scenarios and solving pain points such as wear, deformation, jamming and rusting of rotating shafts. It is compatible with various original factory rotatable parts.
