Finer PT 24B2-13PB Pilot Bore Sprocket – 24B-2 Duplex – 1-1/2″ Pitch – 13 Teeth

The Finer PT 24B2-13PB is a 13 tooth pilot bore sprocket for 24B-2 duplex British Standard roller chain – 1-1/2″ (38.1mm) pitch. It has a 159.18mm pitch circle diameter (PCD) and a 174.2mm outside diameter. It comes with a 25mm 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): 114 mm
• Overall length (A): 100 mm
• Tooth width (B2): 72 mm
• Tooth radius (r3): 38 mm
• Radius width (C): 4 mm
• Approx. weight: 9.92 kg
• Chain: 1-1/2″ (38.1 mm) pitch – 25.4 mm inside width – 25.4 mm roller diameter

BS / ASA interchange (1-1/2″ pitch – BS 24B-1 and ASA 120-1): BS sprockets will wrap ASA chain (not recommended for frequent forward/reverse indexing) but ASA sprockets may need to have the teeth skimmed to wrap BS chain – the plate thickness differs.

Please note: this pilot bore sprocket is supplied with a 25mm pilot bore – it is not finish bored.
