Short pitch precision roller chain(A series)

ANSI Standard Short Pitch Power Transmission Roller Chains are the most popular chains for driving, transmission reduction, tension, shuttle traction, and other applications. ANSI standard roller chains are produced according to with ISO 606A, ANSI B29.1M and DIN 8188 from high quality steel and incorporated with latest manufacturing technologies. Products are available from pitch size 6.35 to 76.2 mm in single,multiple and triple strands, riveted or cottered.

1. To suit specific working conditions, the following versions are also available: bushed chain (with the omission of rollers), straight linkplate chain, heavy-duty chain, super strength chain, stainless steel chain, nickel-plated chain, zinc-plated chain, copper-plated chain, dacrotised chain, hollow pin chain, side bow chain, o-ring chain,and engineering plastic chain.

2. Unless cottered construction chains are requested, products are supplied in riveted construction. Please note the above multiple strand roller chains should not be used as oil field chains. For oil field roller chains, please inform us.

3. Unless otherwise requested, all ANSI Standard Roller Chains are packed in 3.048 meter (10 feet) per length including one connecting link. Offset links are used for adjust chain length. When used for perform power transmission at high speed or heavy-duty power transmission, two-pitch offset links (one inner link and one offset link) are recommended.
