Straight side plate roller chain, as the name suggests, the chain plate is straight, and the side plate design has certain characteristics. This kind of chain is usually composed of an inner chain plate, an outer chain plate, a pin, a sleeve and a roller, wherein the roller and the sleeve, the sleeve and the pin are gap coordination, working between the inner and outer chain nodes can be relatively deflected, the sleeve can be freely rotated around the pin shaft, and the roller is set on the sleeve to reduce the wear between the chain and the sprocket. The design of the straight side plate helps to enhance the side stability of the chain and reduce the side offset, thus improving the transmission efficiency and accuracy.

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.


Why Choose Us


Custom Plate Thickness: Offer 3mm to 15mm side plate options for tailored stiffness in unique load scenarios.

3D Alignment Analysis: Free CAD-based drive system simulation to optimize chain tension and sprocket alignment.

Quick-Change Links: Patented master links reduce downtime by 50% during maintenance or replacement.

Global Inventory Network: 20+ distribution centers ensuring 48-hour delivery for standard A Series chains.
