SSY005237969 Pin Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

SSY005237969 Pin Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The SSY005237969 pin is compatible with tracked equipment such as Sany excavators and rotary drilling rigs, and is widely used at hinge points in the machine body, boom, stick, and connecting rod. As a precision connecting shaft, it connects moving components, evenly distributes working loads, and controls clearances. Combined with oil seals and bushings, it completes high-frequency bending and rotating movements, making it a core wear component that ensures sensitive operation and stable running of the equipment.
This product is made of high-strength steel, processed through quenching, tempering, and precision grinding. The shaft has precise roundness, a hard and smooth surface, and is resistant to shear, compression, and fatigue wear, making it suitable for heavy-duty and harsh working conditions such as mining and earthmoving. Old pins, subjected to long-term erosion from mud and sand and heavy-load impacts, are prone to wear, grooving, bending, rust, and loose fit, leading to hinge vibration, oil leaks, abnormal noises, and sluggish movement, reducing operational accuracy. This product features original factory dimensions and high coaxiality, allowing for non-destructive replacement of old parts. It is suitable for routine maintenance and bulk stocking, effectively restoring hinge accuracy and reducing maintenance costs.
