About #100-2 Roller Chain

#100-2 is ANSI B29.1 standard duplex roller chain with 1.25-inch pitch, engineered for heavy-load power transmission. Made of premium carbon steel, all pins, rollers and link plates undergo precise heat treatment and shot peening to boost tensile strength, wear resistance and anti-fatigue performance.

Its double-strand structure delivers higher bearing capacity than single-row #100 chain, running smoothly with low friction and stable transmission efficiency. Fully interchangeable with standard #100 sprockets for easy installation and replacement. Widely applied in conveyors, agricultural machinery, industrial production lines and heavy-duty drive equipment, offering reliable long-term operation and low maintenance cost.
