Description
This unit guides and tensions roller chain, combining a sprocket with an integrated bearing on a fixed bore of 20.0 mm. The outside diameter is 47.0 mm and the unit weighs 0.26 kg net, with the sprocket produced from steel or sintered iron. The compact hub design allows direct mounting on a shaft without additional adapter parts, keeping the chain properly guided while supporting rotation on the built-in bearing. The sealed construction protects the internal bearing from contamination, making the unit suited for chain drive sections where a fixed idler or tensioning point is required.
