SKF Sprocket, 28 Teeth, 32mm Width - PHS 10B-1TB28

This sprocket is a toothed drive component designed for use in chain-driven industrial systems. It transmits rotary motion between shafts via a compatible roller chain and is intended for installations requiring a tapered bore mounting and robust steel construction. The component meets recognised EN and BS approvals and is suitable for medium-to-heavy duty power transmission within mechanical assemblies.

Features and Benefits:

• Tapered bore enables secure interference fit for shaft mounting
• 28 teeth deliver consistent engagement with roller chain
• Steel construction offers Durable wear resistance under load
• Compatible with 12B-2 chain for standardised drive pairing
• 32mm width supports lateral stability during operation

Applications

• Suitable for conveyor drive stages in factories
• Used with transmission shafts requiring taper mounting
• Ideal for machinery employing 12B-2 roller chain
• Can be used for power transfer in material handling
• Used for retrofit of metric chain drive assemblies

What hub Interface is provided for mounting?

The component is supplied with a hub diameter of 90mm allowing connection to tapered bushings for shaft attachment.

What is the internal clearance available for shaft insertion?

The maximum inside diameter is 50.8mm which defines the largest shaft size accommodated when using the tapered bore arrangement.

Which pitch specification does the toothed profile correspond to?

The pitch diameter measures 141.78mm indicating the sprocket pitch geometry for chain engagement.

What chain specification should be paired for correct operation?

A 12 B-2 type chain is specified for compatibility to ensure correct tooth engagement and load distribution.

How thick is the sprocket to support side loading?

The sprocket has a face width of 32mm providing a contact area to resist lateral forces.
