Spring Pin DZ9114520005 SHACMAN

Product Introduction

Structure

This spring pin is a precision-machined alloy steel component, featuring a stepped cylindrical design with a smooth main body, a threaded end for nut retention, and a hexagonal nut for secure clamping. It is equipped with a high-durometer rubber seal to prevent corrosion and wear at the interface with the leaf spring assembly. The surface is precision-ground to ensure a tight fit and optimal load distribution.

Performance

Forged from high-strength alloy steel and heat-treated for maximum toughness, it withstands extreme shear forces and repeated impact loads inherent in heavy-duty suspension systems. The rubber seal provides reliable protection against rust, salt spray, and chemical corrosion, ensuring consistent performance in temperatures ranging from -40°C to 120°C.

Core Function

1. Serves as the primary pivot and clamping component for the leaf spring assembly, securing the spring stack to the hanger or shackle while allowing controlled articulation.

2. Transmits shear and impact loads from the leaf spring to the chassis, distributing forces evenly to prevent structural damage and premature wear.

3. Maintains precise alignment of the leaf spring assembly, ensuring consistent spring rate and performance during operation.

4. Resists loosening under sustained vibration and heavy impacts, preventing premature failure of the leaf spring system and ensuring safe and reliable operation of heavy-duty trucks.
