High-Stiffness Straight Side Plate Roller Chains for Industrial Drives (A SERIES)
Overview
The High-Stiffness Straight Side Plate Roller Chains (A Series) are engineered for heavy-duty industrial applications requiring maximum structural rigidity and consistent load distribution. Featuring precision-machined straight side plates and heat-treated components, these chains eliminate lateral deflection under high tension, delivering reliable power transmission in demanding drive systems. The robust design balances high tensile strength with smooth articulation, making them ideal for machinery subject to shock loads or misalignment.
Features
Straight Side Plate Design: Thicker, flat-profile plates (15-25% stiffer than curved designs) reduce plate bending, ensuring uniform load distribution across all links.
Enhanced Tensile Strength: Heat-treated alloy steel pins (62HRC) and bushings provide tensile ratings from 12kN to 100kN, with a 1.8x safety factor for sudden load spikes.
Low Friction Operation: Polished rollers (Ra≤0.8μm) and precision-matched bushing bores minimize energy loss, improving drive system efficiency by 12%.
Corrosion Protection: Optional duplex coatings (zinc-nickel base + PTFE topcoat) offer 1,000+ hours of salt spray resistance (ASTM B117), suitable for outdoor or marine environments.
ANSI/ISO Compliance: Meets ANSI B29.1 (A Series) and ISO 606 standards, ensuring compatibility with global sprocket systems.
Application
Heavy Machinery: Powers cement mill drives, steel rolling mills, and paper machine presses requiring stable torque transfer.
Mining Conveyors: Used in long-distance belt conveyors and bucket elevators in underground mines, resisting dust and abrasive particles.
Construction Equipment: Drives crawler tracks on excavators and bulldozers, withstanding repeated impact from uneven terrain.
Industrial Gearboxes: Integrates with reducers and gear drives in packaging machinery and material handling systems.
