ANSI #120 Roller Chain

ANSI #120 roller chain is manufactured strictly in accordance with ANSI B29.1 standard, featuring a 1.5-inch pitch. Made of high-quality carbon steel, its pins, rollers and link plates undergo professional heat treatment to achieve high tensile strength, excellent fatigue resistance and outstanding wear resistance for heavy-load transmission. The chain is pre-stretched during production to minimize initial elongation, ensuring stable, low-vibration long-term operation and less frequent tension adjustment. It is widely used for heavy-duty power transmission and conveying equipment, including large conveyors, agricultural machinery, construction equipment, mining machinery and industrial drive systems. Stainless steel, plated surface and customized attachment versions are available to fit corrosive, humid or special conveying working conditions.
