The illustration beneath shows component parts from the outer link and of your inner website link of the basic roller chain. As illustrated, the precision steel roller chain includes a series of journal bearings held in exact relationship to each other by the constraining link plates. Each and every bearing includes a bearing pin and bush on which the chain roller revolves. The bearing pin and bush are situation hardened to allow articulation under high pressures, and to contend with the load carrying pressures and gearing action imparted via the chain rollers. All chains are classified according to pitch (the distance amongst the centers of adjacent bearing pins), roller diameter and width concerning inner plates. Collectively, these dimensions are referred to as the gearing dimensions, as they ascertain the form and width with the sprocket teeth.
