SSY004936691 Hinges Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

This product is a genuine SANY hinge accessory, compatible with moving structures such as side doors, maintenance hatches, and engine covers. It is responsible for rotational opening and closing, limit support, and buffer positioning, ensuring smooth door opening and closing, stable angles, and improving issues such as jamming, sagging, abnormal noises, gap misalignment, and incomplete closure. Original factory holes require no modification; it can directly replace worn, rusted, or deformed old hinges, suitable for equipment maintenance, new machine installation, and bulk stocking.
This hinge is forged from high-strength alloy steel, making it sturdy, tough, and highly resistant to wear, bending, and fatigue. The precisely fitted shaft ensures even opening and closing damping, preventing jamming or loosening even after long-term reciprocating operation. It stably supports the weight of the door, distributing opening and closing stresses from vibrations and avoiding problems such as deformation, shaft wear, and opening/closing misalignment caused by heavy loads and bumps. Suitable for harsh working conditions such as mining, infrastructure construction, and heavy earthmoving, it is resistant to rust, jamming, loosening, and sagging even after long-term use, ensuring door opening and closing accuracy and sealing, and reducing equipment noise and maintenance costs.
