High Strength Duplex Short Pitch Roller Chain

Product Description

Our Short Pitch Roller Chains are designed for efficient power transmission in a wide range of industrial applications. Featuring standardized dimensions, precise manufacturing, and reliable performance, they ensure smooth operation, high transmission efficiency, and long service life.

Key Features & Benefits

• High Strength & Durability: Manufactured from premium alloy steel, heat-treated for optimal core toughness and case-hardened pins/bushings for superior wear resistance. Built to withstand heavy loads and continuous operation.
• Precision Engineering: Each component—inner plates, outer plates, pins, bushings, and rollers—is manufactured to exacting international standards (ISO, ANSI, DIN) for perfect fit, smooth articulation, and consistent engagement with sprockets.
• Optimized Efficiency: The free-rolling roller design minimizes friction with the sprocket tooth, reducing power loss and enhancing overall drive system efficiency.
• Excellent Fatigue Resistance: Precision-plate construction and high-quality materials provide exceptional resistance to the dynamic stresses of high-speed cyclic loading.
• Low Maintenance & Easy Installation: Simple, robust design allows for easy inspection, lubrication, and replacement. Compatible with standard sprockets worldwide.
• Versatile Configurations: Available in single strand (Series) and multiple-strand (Duplex, Triplex) designs to accommodate a wide range of horsepower and load requirements.

Scope of Application

These chains are integral to a vast array of machinery:

• General Industrial Machinery: Drives for pumps, compressors, fans, and reduction units.
• Agricultural Equipment: Transmissions and drives for tractors, harvesters, and processing equipment.
• Material Handling: Light and medium-duty conveyors, feeders, and lift mechanisms.
• Motorcycles and Bicycles: Widely used for final drive transmission.

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.
