SSY004949681 Middle Support I Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The SSY004949681 central support bracket I is a core load-bearing component of the SANY original chassis. Mounted in the middle of the chassis, it is responsible for structural fixation, load support, and frame reinforcement. It can distribute concentrated loads in the middle, buffer against bumps and vibrations, and improve issues such as component loosening, misalignment, abnormal noise, and frame looseness. Original factory mounting holes require no modification; it can directly replace old, deformed, rusted, or damaged brackets, making it suitable for equipment maintenance, new machine installation, and bulk stocking.
This product is a key load-bearing component in the middle of the machine body, integrally formed from high-strength alloy structural steel. It boasts ample rigidity, resistance to compression and bending, and resistance to impact and fatigue. It allows for precise positioning of installation points, distributing dynamic stress and preventing deformation, cracking, and loosening caused by heavy-load vibrations. Suitable for harsh working conditions such as mining, infrastructure construction, and heavy earthmoving, it is resistant to rust, deformation, and breakage even after long-term operation. It stabilizes the machine frame, improves overall machine stability, and reduces equipment maintenance costs.

【Core Technical Parameters】
