Nitro high-quality 40 roller chains are built for strength, durability and reliability. Our chains are manufactured from very specific carbon & alloy steel to achieve the highest level of wear & fatigue resistance through precise heat treatment & shot peening. Nitro #40 chain if fully compliant to the ANSI B29.1 standards, which outlines specific dimensional & strength requirements for Amercian roller chain sizes. ANSI compliance also ensures this chain is compatible with any ANSI #40 roller chain sprocket.
The 40-1R roller chain is commonly referred to as a 1/2" pitch chain, which is the pin to pin measurement.
