The Finer PT 40A1-9PB is a 9 tooth pilot bore sprocket for ASA 40-1 simplex roller chain – 1/2″ (12.7mm) pitch. It has a 37.13mm pitch circle diameter (PCD) and a 43.2mm outside diameter. It comes with a 10mm pilot bore.

A pilot bore sprocket is supplied with a small starter bore so it can be machined out to suit the shaft – keyway and set screws. Finer sprockets are made from high quality steel with induction hardened teeth – improving resistance to wear and extending working life. All Finer sprockets are engineered in accordance with ISO 9000 standards.

  • Radius width (C): 1.6 mm
  • Approx. weight: 0.14 kg

BS / ASA interchange (1/2″ pitch – BS 08B-1 and ASA 40-1): BS sprockets will wrap ASA chain but ASA sprockets will not wrap BS chain – the roller diameters differ.

Please note: this pilot bore sprocket is supplied with a 10mm pilot bore – it is not finish bored.
