Double Pitch Conveyor Chain with Special Attachments
Engineered for efficient, customized material handling in low-speed, long-distance scenarios, the Double Pitch Conveyor Chain with Special Attachments integrates the energy-saving advantages of double pitch design with tailor-made attachments. Adhering to ANSI B29.1 and ISO 606 standards, this chain features a pitch length twice that of standard roller chains, paired with specialized fixtures precision-designed for unique conveying needs. It excels in scenarios requiring stable transport of bulk goods, irregular workpieces, or niche load requirements, making it a reliable solution for logistics, manufacturing, and processing industries.
Core Advantages: Double Pitch Efficiency & Specialized Attachments
The chain’s double pitch structure (25.4mm to 63.5mm) is the cornerstone of its efficiency, reducing the number of links and sprocket teeth needed for long-distance conveying. This design lowers chain weight, friction, and wear, directly cutting energy consumption and maintenance frequency compared to standard pitch chains. What sets it apart is its special attachments—fully customizable to address limitations of standard fixtures, including curved brackets for cylindrical products, anti-slip clamps for fragile items, extended arms for large components, and heat-resistant fixtures for high-temperature processes.
Built for durability in demanding conditions, the chain core is crafted from high-grade carbon steel (1045) or alloy steel (20Mn2), with rollers, pins, and bushings undergoing carburizing, quenching, and tempering. This achieves a surface hardness of HRC 58-62 for wear parts and a tough core (HRC 38-42) to resist impact. Special attachments are firmly welded or bolted to reinforced straight side plates, with enhanced connection points to withstand dynamic loads and prevent detachment—critical for niche applications where attachment failure risks downtime.
Versatility is further enhanced by modular design and protective treatments. Available in single-strand and double-strand configurations, it covers working load capacities from 6kN to 90kN, adapting to light to medium-heavy duty needs. Optional surface treatments—hot-dip galvanizing, PTFE coating, and food-grade nickel plating—provide targeted protection against corrosion, abrasion, and hygiene risks. The chain supports operating speeds of 0.1m/min to 3m/min, optimized for low-speed, high-capacity conveying, and is compatible with standard double pitch sprockets for easy system integration.
Structural Excellence & Operational Resilience
Designed for complex layouts, the chain maintains stability on straight, curved, and inclined paths (maximum climbing angle 25°). Its double pitch roller-bushing assembly minimizes contact friction with rails and sprockets, reducing noise (≤55dB) and extending service life. Reinforced side plates prevent lateral deflection, even when special attachments exert offset loads, while heat-treated components withstand temperature fluctuations from -20℃ to 130℃—adapting to humid workshops, dusty processing plants, and moderate high-temperature environments.
Safety and maintainability are integrated into every detail. Special attachments feature rounded edges to prevent material damage and debris accumulation, reducing jamming risks. The chain supports cottered and spring clip connections for on-site assembly and length adjustment, without specialized tools. Predictable wear patterns enable proactive maintenance, while standardized core components ensure easy replacement of links or attachments—minimizing operational interruptions.
