SKF 25 Tooth Taper Bush Sprocket, PHS 08B-2TBH25 08 B-2

This sprocket is a steel transmission wheel designed to transfer rotary motion in chain-driven systems where a taper bush mounting is required. It functions as a drive or driven sprocket compatible with 08B-2 roller chain and integrates with tapered bore hubs to secure the component on shafts in industrial conveyors and machinery.

• 25 teeth deliver consistent engagement and torque transmission
• 32mm width supports stable chain seating and load distribution
• 101.33mm pitch diameter ensures accurate chain pitch alignment
• Taper bore allows precise, concentric mounting on shafts
• 87mm hub diameter provides robust axial support for loads
• Max inside diameter 50.8mm permits larger shaft accommodation

• Used with 08B-2 chain in light-to-medium conveyor drives
• Suitable for industrial machinery requiring taper bore mounting
• Ideal for rehabilitation of drive trains with 25T sprockets
• Can be used for replacement of worn steel drive wheels
• Used for retrofitting shaft assemblies with larger bores

The component is manufactured from steel which provides the necessary hardness for contact with roller chain.

The hub diameter of 87mm increases bearing span and reduces bending loads on the shaft during operation.

The maximum internal opening permits shafts up to 50.8mm in diameter to be accommodated.

It is designed to operate with 08B-2 roller chain to maintain correct pitch engagement.

The taper bush arrangement enables axial tightening for accurate centring and reduced runout when mounted.
