SKF Sprocket, 25 Teeth, 152mm Pitch Diameter - PHS 12B-2BH25

This sprocket is a toothed drive component designed to engage a 12 B-2 roller chain for power transmission in mechanical and automation systems. Manufactured from steel, it is intended for installation where a hubbed sprocket with a rough stock bore is required and is suitable for use in environments that conform to EN and BS norms.

Features and Benefits:

• 25 teeth deliver consistent chain engagement and smooth torque transfer
• 152mm pitch diameter supports accurate chain alignment
• 50mm width provides stable lateral chain support during operation
• Steel construction resists deformation under cyclic loads
• Rough stock bore accepts machining for tailored shaft fit
• Hub diameter of 120mm offers solid mounting for heavy-duty drives

Applications

• Suitable for conveyor drives in manufacturing lines
• Ideal for chain-driven transmission systems in automation
• Used with 12 B-2 chain in material handling equipment
• Can be used for replacement of worn sprockets in industrial gearboxes
• Suitable for retrofitting mechanical powertrains in plant machinery

What bore sizes can be finalised when machining the rough stock bore?

The pre-bored centre can be machined to any diameter up to 60mm to suit shaft dimensions between 20mm and 60mm.

How does the hub diameter affect mounting stability?

A 120mm hub diameter increases contact area with the mounting assembly, improving concentricity and reducing eccentric loading on the shaft.

How does the pitch diameter influence chain selection and alignment?

The 152mm pitch diameter determines the correct chain wrap and centre distance calculations for 12 B-2 chain drives, aiding accurate drive design.
