SKF Sprocket, 152mm Pitch Diameter, Taper Bore - PHS 12B-1TBH25

This sprocket is a steel rotary drive component designed for use in taper-bore chain drive systems, transmitting torque between shafts and roller chain in industrial settings. It fits onto a tapered mounting arrangement and mates with compatible roller chain to provide reliable power transfer where discrete tooth engagement is required.

Features and Benefits:

• Taper bore enables accurate, adjustable hub mounting
• 25 teeth permit smooth engagement with matched chain
• Steel construction offers wear resistance under cyclic load
• BS EN approval supports use in regulated installations
• Compatible with 12B-1 chain for standard industrial drives

Applications

• Used with taper-mounted drives in factory conveyors
• Suitable for replacement on maintenance overhaul projects
• Ideal for power transmission with 12B-1 roller chain
• Can be used in material handling sprocket trains
• Used for synchronising rotary components in plant equipment

What mounting arrangement does it require?

It requires a tapered bore fit that secures the sprocket to a matching taper shaft adaptor for axial and radial locating.

Which chain specification will engage correctly?

It is designed to work with 12B-1 roller chain profiles, ensuring compatible pitch and roller engagement.

What material properties affect its service life?

Manufacture from steel provides hardness and fatigue resistance relevant to cyclic tooth loading and wear performance.

How does the hub configuration influence installation?

The hub diameter is sized to Interface with the taper assembly and transmit torque through the taper-mounted hub rather than the bore alone.

What tooth count impacts rotational speed relationships?

With 25 teeth, it establishes the sprocket’s speed ratio when paired with other sprockets, affecting final drive speed and torque distribution.
