SKF 22 Tooth Rough Stock Bore Sprocket, PHS 06B-1BH22 06 B-1

This sprocket is a steel transmission wheel designed to engage roller chain in power-transmission systems within industrial settings. It is intended for use in driven or driving positions where compatible 06 B-1 chain is employed, providing a Durable Interface between rotating shafts and chain drives in automation and mechanical assemblies.

• 22-tooth configuration delivers consistent engagement and reduced vibration
• 35mm rough-stock bore allows precise final machining to shaft tolerances
• 50mm hub diameter provides enhanced load distribution on the hub
• 66.93mm pitch diameter ensures accurate chain pitch alignment
• 28mm width accommodates standard chain thicknesses for stable operation
• Steel construction offers high wear resistance for continuous duty

• Suitable for conveyor drives in automated production lines
• Ideal for timing and indexing mechanisms in assembly equipment
• Used with industrial 06 B-1 chain in material-handling systems
• Can be used for retrofit replacements in existing chain-drive gearboxes
• Suitable for drive shafts in electrical actuator assemblies

The bore is supplied as rough stock, so it requires final machining to match the EXACT shaft diameter and keyway specifications for a secure interference or fitting tolerance.

A larger hub diameter spreads contact stresses over a greater surface area, lowering bearing loads and improving resistance to hub deformation under radial and torsional forces.

It meets recognised EN and BS standards relevant to component dimensions and manufacturing tolerances applied during production.

Using the 22-tooth profile maintains smoother engagement with the chain, reducing shock loads per revolution and assisting in even wear distribution across chain links.
