The High Quality Loader Steering Hinge Pin Custom Steel Pin Suitable For SDLG 955F is produced using high-performance raw materials selected to meet the demanding conditions of heavy machinery. We offer a range of materials tailored to provide optimal strength, durability, and resistance to wear, ensuring long-lasting performance.

For the pin shaft, we use carefully chosen materials such as 45C, 41Cr4, 42CrMo4, and 35CrMo4 (European standards), 1045, 5140, 4140, and 4135 (American standards), and 45#, 40Cr, 42CrMo, and 35CrMo (Chinese standards). These materials are known for their superior hardness, tensile strength, and resistance to corrosion, making them ideal for the demanding environments where loaders like the SDLG 955F operate.

The bushing is crafted from a variety of high-quality materials, including 20CrMo44, 45C, 41Cr4, and 42CrMo4 (European standards), 4119, 4118, 1045, 5140, and 4140 (American standards), as well as 20CrMnTi, 20CrMo, 45#, 40Cr, and 42CrMo (Chinese standards). These materials offer exceptional wear resistance and corrosion protection, ensuring the bushing fits perfectly with the pin shaft and contributes to the overall efficiency of the loader's steering system.

By utilizing these advanced materials, Shanghai Fenghua International Enterprise Co., Ltd. ensures that the High Quality Loader Steering Hinge Pin meets the highest standards of durability and performance, providing reliable operation for SDLG 955F loaders in even the toughest working conditions.

1. Material Selection and Inspection

The production of the High Quality Loader Steering Hinge Pin begins with the careful selection of raw materials, ensuring they meet the necessary specifications for strength, durability, and corrosion resistance. Materials like 45C, 41Cr4, and 42CrMo4 (European standards) are rigorously inspected to ensure consistent quality and suitability for heavy-duty applications.

2. Precision Machining

Once the raw materials are approved, the pin undergoes precision machining processes. This includes cutting, shaping, and fine-tuning to meet the exact specifications required for the SDLG 955F loader's steering system. High-precision CNC machines ensure that each pin shaft is manufactured to strict tolerances, offering a perfect fit with other components.

3. Induction Hardening and Surface Treatment

To enhance the strength and wear resistance, the pin undergoes induction hardening. This process ensures the pin achieves the necessary hardness to endure high-stress conditions. Afterward, surface treatments such as zinc plating or chrome coating are applied to provide additional protection against corrosion, ensuring long-term durability in challenging environments.

4. Precision Welding and Assembly

After the components are fully machined and treated, the pin's parts are welded together using advanced industrial robotic arms. This automated welding process ensures strong, uniform welds that improve the structural integrity of the pin. The final assembly step includes the fitting of the bushing and the pin shaft, ensuring they align perfectly for smooth operation.

5. Quality Control and Final Testing

Before the product is shipped out, it undergoes rigorous quality control checks. Every High Quality Loader Steering Hinge Pin is tested for strength, hardness, and dimensional accuracy to meet industry standards. Comprehensive testing ensures the pin performs as required under real-world working conditions, providing reliable and long-lasting service for the SDLG 955F loader.
