Simply Bearings carries a comprehensive range of parts for automotive and industrial applications, including duplex roller chains. Our Renold precision steel roller chains come in a full range of pitches to suit any application where the efficient transmission of mechanical power is required, be it domestic, industrial or agricultural. The Renold chain achieves up to 98% mechanical efficiency, depending on operating conditions.

The Renold chain has been in use since 1880, when it was fitted to the first modern bicycles. Since then, duplex roller chains have become standard on cars, motorcycles, forklifts, chainsaws and even the Harrier Jump Jet. With a simple link construction, the roller chain reduces friction, resulting in far greater efficiency and resistance to wear.

At Simply Bearings we supply both European standard duplex chains and American standard duplex chains. American standard duplex chains have a smaller pin diameter than the European equivalent, which reduces wear resistance except in the case of 5/8th pitch chain. In this sizing, the pin and bush diameter are actually larger in the American standard.

Both American and European standard duplex chains are manufactured in the same way and to the same high standard for extremely efficient power transfer. In industrial applications, this efficiency has seen the Renold's chain supersede all others. In a Renold's chain, the journal bearings are held in a precise relationship to each other by the link plates, with each bearing consisting of a bearing pin and bush on which the roller revolves. These components are case hardened, which allows them to articulate even under high pressure.
