Finer PT 60A1-30PB Pilot Bore Sprocket – ASA 60-1 Simplex – 3/4″ Pitch – 30 Teeth

The Finer PT 60A1-30PB is a 30 tooth pilot bore sprocket for ASA 60-1 simplex roller chain – 3/4″ (19.05mm) pitch. It has a 182.25mm pitch circle diameter (PCD) and a 190.6mm outside diameter. It comes with a 20mm 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.

Dimensions:

• Hub diameter (dm): 95 mm
• Overall length (A): 40 mm
• Tooth width (B1): 11.6 mm
• Tooth radius (r3): 20 mm
• Radius width (C): 2.4 mm
• Chain: 3/4″ (19.05 mm) pitch – 12.7 mm inside width – 11.91 mm roller diameter

BS / ASA interchange (3/4″ pitch – BS 12B-1 and ASA 60-1): BS sprockets will wrap ASA chain (not recommended for frequent forward/reverse indexing) but ASA sprockets will not wrap BS chain unless the teeth are skimmed – the plate thickness differs.

Please note: this pilot bore sprocket is supplied with a 20mm pilot bore – it is not finish bored.
