Finer PT 06B2-21T/L Taper Lock Sprocket – 06B-2 Duplex – 3/8″ Pitch – 21 Teeth – 1008 Bush

The Finer PT 06B2-21T/L is a 21 tooth taper lock sprocket for 06B-2 duplex British Standard roller chain – 3/8″ (9.53mm) pitch. It has a 63.91mm pitch circle diameter (PCD) and a 67.6mm outside diameter. It is bored to take a 1008 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.
