Industry Leading Fatigue Strength Harvester Chains

Product Description

Our Harvester Chains are specifically engineered to withstand the most demanding agricultural environments. Whether you are harvesting corn, wheat, rice, or soybeans, our chains provide the high tensile strength and wear resistance required to keep your machinery running at peak efficiency during the critical harvest window.

Key Features & Benefits

• Superior Durability: Manufactured from high-grade alloy steel with advanced heat-treatment processes (carburizing and quenching) to ensure maximum hardness and fatigue resistance.
• Precision Engineering: Each link is built to exact pitch specifications, ensuring smooth engagement with sprockets and reducing vibration and noise.
• Enhanced Wear Resistance: Pins and bushes are precision-ground and hardened to minimize elongation, significantly extending the service life even in dusty and abrasive conditions.
• Pre-Stretched & Pre-Lubricated: All chains undergo factory pre-stretching to reduce initial "stretch" and are treated with high-performance lubricants to prevent rust and friction from day one.
• Corrosion Protection: Optional coatings (such as zinc plating or Dacromet) are available for harvesters operating in high-moisture or coastal environments.

Scope of Application

1.Combine Harvesters

• Header Conveying: Gentle crop transfer from cutter bar

• Straw Walkers: Separation and ejection systems

2.Forage Harvesters

• Crop Gathering: Collection from cutting units
• Processing Feed: Transfer to chopping mechanism
• Blower Systems: Material movement to storage

3.Specialty Harvesters

• Cotton Pickers: Gentle fiber handling chains
• Potato Harvesters: Dirt-removing conveyor chains
• Grape Harvesters: Delicate fruit handling systems
• Sugar Cane Harvesters: Heavy-duty, high-capacity chains

Close cooperation with factories

We maintain deep, long-term partnerships with the factory around 20 years. The factory has strong mechanical and automated production capabilities which ensure stable quality and performance of the products.

Quality control

The factory's rigorous quality control process includes material spectroscopy analysis, in-process inspections, and final checks with Magnetic Particle Testing (MPT) to ensure every bucket is free from defects and meets our high standards. The details control process as below,

1. Incoming raw materials undergo random sampling and analysis using a microscope to ensure the chemical composition meets production requirements.

2. During the production process, QC staff conduct timely sampling to ensure products are defect-free and handle any abnormal quality issues that may arise.

3. The final step involves using a magnetic particle flaw detector on metal parts to detect hidden cracks or defects.

4. All finished metal parts are proportionally sampled and sent to the laboratory for mechanical performance tests, size measurement, and 100% manual surface quality inspection.

Why Choose Us?

We understand that downtime is not an option during harvest season. Our quality control processes ensure that every foot of chain meets international standards (ISO/ANSI/DIN), providing you with a cost-effective solution that reduces maintenance frequency and maximizes your yield.
