SKF 48 Tooth Rough Stock Bore Sprocket, PHS 08B-1B48 08 B-1

This sprocket is a toothed drive component designed for power transmission with 08B-1 roller chains in industrial systems. Manufactured from steel, it is intended for integration into mechanical drives where chain engagement and torque conveyance are required. The unit conforms to BS EN standards and suits applications demanding standardised sprocket geometry and material robustness.

• 48 teeth deliver consistent chain engagement and load transfer
• 194.18mm pitch diameter ensures precise chain tracking
• Steel construction offers wear resistance under cyclic loading
• 40mm hub width supports stable lateral chain guidance
• Hub diameter 90mm provides secure mounting for coupled assemblies

• Suitable for conveyor drives in automation lines
• Ideal for reduction drives in electrical motor assemblies
• Used with timing chains in mechanical handling equipment
• Can be used for retrofit replacements in industrial gear trains

The component is supplied with a rough stock bore that can be machined to final diameters between 16mm and 64mm to match shaft tolerances.

The maximum inside diameter is 64mm, which defines the largest shaft size after finishing that can be accommodated without additional adaptors.

It is designed for 08 B-1 chain engagement, so selection should match chain pitch class to maintain correct articulation and service life.

The 90mm hub diameter concentrates mounting forces centrally, so fastener design and hub fitment should account for imposed radial and axial loads.
