Short Pitch Precision Roller Chain

Short pitch precision roller chains are standardized power transmission components manufactured in accordance with ISO and ANSI industrial specifications, classified into Series A and Series B for global industrial matching. This product adopts uniform short pitch as the core dimensional standard, with complete and standardized component parameters, including outer link plates, inner link plates, rollers, pins and bushings.​ In terms of material specifications, all metal parts are made of high-quality alloy carbon steel. Key bearing components such as pins and bushings undergo integral quenching heat treatment, while link plates are processed with surface hardening. The whole chain maintains stable hardness specifications to balance toughness and wear resistance.

Dimensionally, every component is produced with micron-level machining tolerance to eliminate assembly gaps, ensuring high coaxiality between pins and rollers.​ For assembly specifications, the chain features compact internal structure and standardized inner width, which can be perfectly matched with supporting standard sprockets. It supports single-row and multi-row customized specifications to meet diverse load demands. Meanwhile, surface anti-rust oil coating serves as basic surface protection. Benefiting from precise dimensional specifications, the chain delivers low running backlash, stable meshing and low operating noise. With unified international specifications and strong part interchangeability, it is the mainstream transmission part for automated machinery, machine tools and conveying equipment.
