Product Description

Heavy Duty Series Cottered Type Roller Chains - Product Introduction

Overview

Our Heavy Duty Series Cottered Type Roller Chains are high-strength, impact-resistant power transmission components strictly manufactured in compliance with ANSI B29.1 and ISO industrial standards. Upgraded from standard roller chains, this heavy-duty series adopts thicker link plate structure and professional cotter pin locking design, specially engineered for harsh working conditions with heavy load, frequent shock and continuous operation. It integrates ultra-high structural rigidity, excellent fatigue resistance and convenient maintainability, serving as a reliable heavy-load transmission solution for industrial and engineering machinery.

Superior Structural Design

Compared with conventional standard chains, our heavy-duty cottered roller chains feature thicker inner and outer link plates, effectively enhancing overall structural strength and anti-deformation capability under extreme loads. The exclusive cottered type fastening structure fixes pins and link plates firmly with high-strength open cotter pins, realizing excellent anti-loosening performance. It avoids chain separation, stretching and failure caused by frequent starting, sudden load changes and shock impact during long-term operation. Meanwhile, precision integral machining ensures consistent pitch accuracy and smooth meshing with standard heavy-duty sprockets, delivering stable transmission and strong structural interchangeability. Single-row, double-row and triple-row specifications are fully available to meet diverse heavy-load working demands.

Premium Material & Durable Performance

This heavy-duty roller chain is forged from high-purity high-grade alloy steel with strict standardized heat treatment including overall quenching and tempering. The optimized processing technology greatly improves the chain’s tensile strength, surface hardness and wear resistance. The precision-polished rollers and pins feature low friction coefficient and strong abrasion resistance, reducing operating wear and extending service life greatly. With outstanding fatigue resistance and pressure resistance, the chain can maintain stable mechanical performance under long-duration heavy-load operation, repeated shock load and high-frequency cyclic work, effectively resisting deformation, fracture and fatigue failure. Full specifications of heavy-duty chain models are available to adapt to different heavy-load and high-intensity working scenarios.

Core Advantages

Superior Heavy-load Capacity: Thickened link plate structure greatly improves ultimate tensile strength and bearing capacity, suitable for extreme heavy-load operation beyond standard chain load limits.
Excellent Shock & Fatigue Resistance: Optimized material and structural technology endows the chain with strong resistance to sudden shock load and cyclic fatigue, adapting to frequent start-stop working conditions.
Anti-loosening & High Safety: Reliable cotter pin locking structure prevents pin loosening and chain disconnection, ensuring high operational safety in high-intensity industrial production.
Easy Installation & Maintenance: The cottered design supports quick disassembly, cutting and assembly without complicated grinding processing, greatly reducing maintenance time and labor costs.
Stable & Efficient Transmission: High-precision dimensional control ensures smooth meshing, low vibration and low noise, maintaining high transmission efficiency under long-term heavy-load operation.
High Cost-performance: Ultra-strong durability reduces replacement frequency and equipment downtime, effectively lowering long-term operation and maintenance costs for industrial equipment.

Wide Applications

Tailored for harsh and high-intensity industrial scenarios, our Heavy Duty Series Cottered Type Roller Chains are widely applied to mining machinery, metallurgical equipment, port handling machinery, construction machinery, agricultural heavy equipment, large conveying systems and other heavy-load mechanical transmission equipment. It is the optimal choice for working environments with heavy load, frequent shock, continuous operation and high safety requirements.
