SKF 9 Tooth Rough Stock Bore Sprocket, PHS 10B-1BH9 12 B-2

This sprocket is a steel transmission toothed wheel designed to engage with roller chain in industrial power-transfer systems. It is intended for applications requiring a Compact nine-tooth drive element manufactured to recognised British and European standards, supplied with a rough stock bore to allow final machining for bespoke shaft interfaces.

• Nine teeth provide Compact torque transfer for short-centre drives
• Accepts 12B-2 chain to maintain standardised chain engagement
• Solid steel construction offering high wear resistance under load
• Rough stock bore enables customised final bore preparation
• Hub diameter 30 mm for secure mounting to a machined hub

• Suitable for conveyors with short-length chain runs
• Used with 12B-2 chain in light-to-medium duty drives
• Ideal for retrofitting Compact gearbox output shafts
• Can be used for bespoke drive assemblies requiring custom bores

The component is supplied with a rough stock bore so the user can machine the internal diameter to the required fit and tolerance for the intended shaft.

It is designed to engage 12B-2 chain profiles manufactured to compatible pitch and roller dimensions for correct mesh.

The steel construction provides increased resistance to contact fatigue and abrasive wear compared with non-metallic alternatives, supporting sustained service in cyclic loading.

The component meets recognised British and European approvals referenced in its specification to assist selection for regulated applications.
