#80-3 cottered roller chain conforms to ANSI B29.1 industrial standards, featuring triple-strand design with a 1-inch pitch. Equipped with cotter pin construction, it enables convenient chain disassembly, length adjustment and quick field maintenance, different from riveted chains.
Critical components including chain plates, pins, bushings and rollers undergo precise heat treatment for high tensile strength, excellent wear resistance and anti-fatigue performance. The triple-row structure offers higher load-bearing capacity for heavy-duty power transmission. It runs smoothly with matched sprockets for steady operation and long service life.
Commonly used in heavy conveyors, agricultural machinery, packaging equipment and industrial transmission devices. Custom lengths, connecting links and offset links are supplied on request.
