Finer PT 08B1-23T/L Taper Lock Sprocket – 08B-1 Simplex – 1/2″ Pitch – 23 Teeth – 1610 Bush

The Finer PT 08B1-23T/L is a 23 tooth taper lock sprocket for 08B-1 simplex British Standard roller chain – 1/2″ (12.7mm) pitch. It has a 93.27mm pitch circle diameter (PCD) and a 98.1mm outside diameter. It is bored to take a 1610 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.

Dimensions:

• Hub diameter (dm): 76 mm
• Overall length (A): 25.4 mm

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 sprocket is bored to take a 1610 taper lock bush – the bush is not included. When requesting a quote – include your shaft size so the matching bush can be supplied.
