As a high-performance derivative of standard short-pitch roller chains, the High-Strength Double Plus Chain is engineered to deliver exceptional reliability, load-bearing capacity, and durability for medium-to-low speed, long-center-distance, and light-to-medium load transmission systems. Designed in compliance with international standards such as ISO 1275 and ANSI B29.3, this chain stands out as a trusted transmission solution across multiple industrial sectors, addressing the core demands of stable operation and extended service life.

Core Features & Technical Advantages

1. Enhanced Tensile Strength for Stable Operation

The chain boasts superior tensile strength, with its ultimate tensile load exceeding industry benchmarks to ensure resistance against breakage under static and dynamic loads. Each component—including pins, bushings, rollers, and link plates—undergoes precision machining and heat treatment, forming a robust structure that maintains structural integrity even in harsh operating environments. The minimum tensile strength (MTS) is strictly controlled to meet or surpass standard requirements, providing a reliable guarantee for high-load transmission scenarios.

2. Optimized Double-Pitch Design

Featuring a pitch twice that of standard short-pitch chains (e.g., 25.4 mm for the double-pitch version of the 12.7 mm 08A chain), the Double Plus Chain offers a lighter overall structure while maintaining excellent transmission efficiency. The extended pitch design reduces the number of components per unit length, minimizing friction and wear during operation, which is particularly suitable for long-center-distance transmission where weight reduction and smooth running are critical.

3. Precision Manufacturing & Wear Resistance

Adopting advanced intelligent production processes, each chain undergoes three rounds of manual screening and two stages of automated quality inspection, ensuring dimensional accuracy with a weight tolerance controlled within ±1 gram. The link plates are made of high-quality alloy steel, and the rollers and bushings are treated with surface hardening technology, significantly enhancing wear resistance and corrosion resistance. This precision manufacturing ensures consistent performance and reduces maintenance frequency.

4. Versatile Structural Adaptability

Available in both transmission-specific and conveyor-specific variants, the High-Strength Double Plus Chain can be customized to meet diverse application needs. For specialized scenarios, sleeve-type double-pitch chains (without rollers) are also offered, providing flexible solutions for different load and speed requirements. Additionally, it supports integration with various sprockets and transmission components, enabling seamless matching with existing equipment.

Application Fields

With its balanced performance of strength, durability, and adaptability, the chain is widely used in:

Conveying equipment: Belt conveyors, roller conveyors for logistics, packaging, and food processing industries.
Light industrial machinery: Printing machines, textile machinery, and packaging equipment that require stable medium-to-low speed transmission.
Agricultural machinery: Farm equipment for crop harvesting and processing, adapting to outdoor and variable load conditions.
Automated production lines: Assembly lines and testing equipment where long-center-distance transmission and low maintenance are essential.
