Steel roller chains are a means of mechanical power transmission that is both versatile and efficient. It's no surprise then that in many industrial applications they've now replaced almost all the other types of chains used in the past.

Our ANSI American standard duplex chains consist of a number of journal bearings which are held in a precise relationship to one another by means of constraining link plates. Each bearing is made up of a combination of bearing pin plus a bush - the chain roller is able to revolve on this. The moving parts are case hardened so the pin and bush can articulate under high pressures, as well as being able to cope with the pressure of load carrying and the gearing action that is imparted by chain rollers.

At Simply Bearings we stock ANSI American standard duplex chains from major brands, including Renolds and Sedis. Chain pitches available range from 3/8 inch up to two inches. If you need full dimensions to make sure you order the right chain, click on the Technical tab on one of the product pages and you'll find a sectioned drawing with full metric dimensions.
