High Strength Double Pitch Roller Chain

Product Description

Our Double Pitch Roller Chain is a specialized derivative of the standard short pitch roller chain, engineered with extended link plates for economical, long-center-distance conveying and light-to-moderate power transmission. When combined with a comprehensive range of attachments, it transforms into a versatile platform for precise material handling, pushing, pulling, and positioning applications across diverse industries.

Key Features & Benefits

• Economical Long-Span Conveying: The extended pitch (twice the standard pitch) significantly reduces the number of links and sprockets required for a given length, lowering overall system cost and weight while maintaining smooth operation.
• High Versatility with Attachments: Available with a wide array of standardized and custom attachments (straight, bent, extended, or special-shaped plates) mounted on pins or rollers, enabling direct handling of products, fixtures, or materials.
• Lightweight & Low Inertia: The design reduces mass per meter, making it ideal for high-speed conveying systems where rapid start-stop cycles are required.
• Excellent Compatibility: Uses the same high-precision rollers, bushings, and pins as our standard chains, ensuring reliable engagement with corresponding Double Pitch Sprockets.
• Reduced Maintenance: Fewer connection points and compatibility with standard lubrication systems simplify upkeep.
• Strong & Durable Base: Manufactured from the same quality alloy steel and heat-treated to ensure the underlying chain retains the necessary tensile strength and wear resistance.

Scope of Application

• Material Handling & Conveying: Assembly line conveyors, pallet handling systems, bottle & can conveyors, package sorting lines, warehouse automation.
• Automated Manufacturing: Positioning systems, fixture transfer, indexing tables.
• Food & Beverage Processing: Washdown-compatible lines (using stainless steel chains).
• Agricultural Machinery: Light-duty conveying sections in harvesters and processing equipment.
• Logistics & Packaging: Carton, tray, and tote box transport systems.

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.
