Finer PT 16B1-17T/L Taper Lock Sprocket – 16B-1 Simplex – 1″ Pitch – 17 Teeth – 2012/2517 Bush

The Finer PT 16B1-17T/L is a 17 tooth taper lock sprocket for 16B-1 simplex British Standard roller chain – 1″ (25.4mm) pitch. It has a 138.2mm pitch circle diameter (PCD) and a 149.8mm outside diameter. It is available bored for a 2012 or a 2517 taper lock bush.

Taper lock sprockets locate on the shaft through a separate tapered bush. The bush carries the shaft bore and keyway – so one sprocket suits a range of shaft sizes – pulls up concentric as the screws are tightened and comes off cleanly for maintenance. All Finer sprockets are engineered in accordance with ISO 9000 standards.

BS / ASA interchange (1″ pitch – BS 16B-1 and ASA 80-1): ASA sprockets will wrap BS chain – BS sprockets will not wrap ASA chain unless the teeth have been skimmed. Take care if using several ASA sprockets on BS chain.

Please note: this sprocket is listed for a 2012 or 2517 taper lock bush – the bush is not included. When requesting a quote – say which bush you need and include your shaft size.
