SKF 30 Tooth Rough Stock Bore Sprocket, PHS 08B-1B30 08 B-1

This sprocket is a steel transmission component designed to engage 08 B-1 roller chain in industrial drive systems. It provides rotational power transfer within mechanical assemblies and is suited to environments that require standard‑compliant sprockets for conveyor, indexing and drive applications.

• Thirty teeth deliver smooth chain engagement and reduced vibration
• 30mm face width improves load distribution across the chain
• 121.5mm pitch diameter ensures accurate chain pitch alignment
• 80mm hub diameter assists stable mounting on shafts
• Steel construction offers wear resistance under cyclic loading

• Suitable for conveyor drives in automation systems
• Used with 08B roller chain as a replacement component
• Ideal for indexing mechanisms in assembly lines
• Can be used for power transmission in electrical cabinet drives
• Used for refurbishment of mechanical drive trains in factories

It is supplied with a rough stock bore enabling final machining to any shaft fit between 16mm and 46mm.

Tooth count and pitch diameter match 08 B-1 chain geometry to maintain correct engagement and minimise accelerated wear.

Ensure the 80mm hub diameter aligns with your hub housing and that bore finishing and the securing method suit operational torque.

The 30mm width distributes axial forces across more chain links, reducing localised stress when aligned and mounted correctly.
