Renold SD 20B-2 BS Duplex Roller Chain 1-1/4 inch Pitch

Renold European (BS) Duplex Chain: The Renold precision steel roller chain is a highly efficient and versatile means of transmitting mechanical power, which, in the field of industrial applications, has almost completely superseded all other types of chain previously used. A Renold precision steel roller chain consists of a series of journal bearings held in precise relationship to each other by the constraining link plates. Each bearing consists of a bearing pin and bush on which the chain roller revolves. The bearing pin and bush are case hardened to allow articulation under high pressures, and to content with the load carrying pressures and gearing action imparted via the chain rollers.
