Description
This unit guides and tensions roller chain drives, combining a sprocket wheel with an integrated bearing support on a single mounting point. The bore diameter is 20.0 mm and the outside diameter is 47.0 mm, with a net mass of 0.45 kg. The sprocket body is made from steel or sintered iron. The integrated bearing allows the sprocket to rotate freely under chain load without a separate housing or shaft support, simplifying installation as an idler or tensioner element in a chain run. Its compact one-piece design keeps alignment fixed once mounted, making it suited for positions where a stationary axis idler is required to guide or maintain chain tension.
