Conveyor Chain with Special Extended Pins
As a specialized material handling solution, the Conveyor Chain with Special Extended Pins is engineered to address unique conveying challenges that require enhanced attachment versatility and load-bearing stability. Designed with precision-extended pins as the core feature, this chain integrates robust structural construction with customized pin designs, adhering to ANSI B29.1 and ISO 606 standards. It excels in scenarios where attachments need extra mounting space, offset positioning, or enhanced load distribution, making it a reliable choice for automated production lines, specialized sorting systems, and heavy-duty material transport across diverse industries.
Core Advantages: Special Extended Pins & Enhanced Performance
The defining feature of this chain is its special extended pins, which are precision-machined to extend beyond the side plates—providing additional mounting space and flexibility for attachments. Unlike standard chains with flush pins, the extended pins can be customized in length (10mm to 50mm beyond side plates), diameter, and thread specifications, supporting a wide range of attachment types including custom brackets, lifting forks, pushing arms, and clamping devices. This design enables offset mounting, multi-layer attachment installation, and direct integration with specialized fixtures, eliminating the need for auxiliary adaptors and reducing assembly complexity.
Built for durability and load-bearing reliability, the extended pins are crafted from high-grade alloy steel (35CrMo, 40MnB) and undergo the same rigorous heat treatment as the chain’s core components—carburizing, quenching, and tempering—to achieve a surface hardness of HRC 60-64 and excellent core toughness. This ensures the pins resist wear, bending, and shear forces even under heavy dynamic loads and frequent start-stop cycles. The chain core features reinforced side plates and precision roller-bushing assemblies, with a tensile strength 20% higher than standard conveyor chains, supporting working loads from 15kN to 180kN across single-strand to triple-strand configurations.
Versatility and adaptability are further enhanced by customizable pin designs and protective treatments. Extended pins can be finished with threads, keyways, or locking grooves to secure attachments firmly, preventing rotation or displacement during operation. Optional surface treatments for both the chain and pins include black oxide, zinc plating, hot-dip galvanizing, and PTFE coating, providing targeted protection against corrosion, abrasion, and high temperatures. The chain covers pitch sizes from 12.7mm to 38.1mm, supporting operating speeds of 0.2m/min to 300rpm, and is fully compatible with standard ANSI sprockets for easy system integration.
Structural Excellence & Operational Resilience
The chain is engineered for stable performance in complex conveying layouts, including straight, curved, and inclined paths (maximum climbing angle 30°). The extended pins are precision-aligned with the chain’s centerline, ensuring balanced load distribution and preventing lateral deflection during operation. The roller-bushing assembly minimizes friction and noise (operating noise ≤58dB), while the reinforced side plates enhance structural integrity, even when attachments exert offset loads. It operates reliably in a temperature range of -30℃ to 140℃, adapting to harsh industrial environments such as high-temperature processing, humid workshops, and dusty construction sites.
Safety and maintainability are integrated into every design detail. Extended pins feature chamfered edges to prevent sharp contact with materials and operators, while locking mechanisms (nuts, cotter pins, or snap rings) secure attachments firmly. The chain supports on-site maintenance with easy-to-replace pins and attachments, and its predictable wear pattern allows for proactive servicing. Standardized core components ensure compatibility with existing conveyor systems, reducing replacement costs and downtime.
