Finer PT 10B2-25T/L Taper Lock Sprocket – 10B-2 Duplex – 5/8″ Pitch – 25 Teeth – 2012 Bush

The Finer PT 10B2-25T/L is a 25 tooth taper lock sprocket for 10B-2 duplex British Standard roller chain – 5/8″ (15.88mm) pitch. It has a 126.7mm pitch circle diameter (PCD) and a 133.6mm outside diameter. It is bored to take a 2012 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.
