Front Spring U-Bolt WG9925520028 Sinotruk

Product Introduction

Structure

This front spring U-bolt is a precision-formed high-strength steel fastener, featuring a U-shaped profile with two parallel, threaded legs. It is manufactured from premium-grade carbon steel or alloy steel, with a uniform diameter throughout the bend and legs. The entire component is coated with a silver-gray zinc or Dacromet finish, providing excellent corrosion resistance. The threaded ends are precision-cut to standard pitch, ensuring compatibility with corresponding nuts and washers for secure clamping.

Performance

Crafted from high-strength steel and subjected to controlled heat treatment, this U-bolt delivers exceptional tensile strength and fatigue resistance, capable of withstanding the extreme clamping forces required to secure heavy-duty truck leaf springs. The corrosion-resistant coating offers superior protection against rust, salt spray, and chemical exposure, ensuring long-term durability in diverse operating environments. It maintains its structural integrity in temperatures ranging from -40°C to 120°C, resisting hydrogen embrittlement and fracture under repeated loading and vibration.

Core Function

1. Securely clamps the leaf spring assembly to the axle housing, maintaining proper alignment and load distribution between the spring and axle.

2. Transmits vertical and lateral loads from the leaf spring to the axle, ensuring stable suspension performance and vehicle handling.

3. Prevents lateral movement and shifting of the leaf spring under heavy loads and dynamic driving conditions, reducing the risk of component failure and improving safety.
