12B-4 roller chain is a metric quad-strand chain with a 19.05mm pitch made per ISO and British Standards. Our superior 12B-4 chain is capable of operating within some of the most demanding applications around the world. Specifically, the chain is assembled using precision carbon and alloy steel components that have undergone heat treatment and shot-peening processes. Post assembly, the 12B-4 roller chain is pre-loaded to a specific amount to reduce initial and long-term elongation. We supply 12B-4 roller chains in lengths of 10ft, including one connecting link per box. Additionally, we offer 12B-4 chain sprockets and chain tools.
