SKF Sprocket, 45 Teeth, 273.1mm Pitch Diameter - PHS 12B-1TB45

This sprocket is a steel drive wheel designed to transmit rotary motion in chain-driven systems using a simplex taper bush for secure mounting. It is intended for industrial conveyor and machinery applications where a compatible chain form and standard approvals are required for integration into existing power-transmission assemblies.

Features and Benefits:

• 45 teeth optimise speed ratio and torque distribution for driven shafts
• Compatible with 12B-1 chain enabling straightforward chain selection
• Steel construction provides high-strength load-bearing capacity
• Taper bush bore affords compact, removable hub attachment
• BS and EN approvals meet recognised national and European standards

Applications

• Suitable for industrial conveyor 45T installations requiring indexed gearing
• Used with 12 B-1 chain in material-handling lines
• Ideal for retrofit drives needing a simplex taper-bore sprocket with 45 teeth
• Can be used for production-line rotary power transfer requiring robust steel sprockets

What is the maximum internal diameter available for mounting?

The maximum internal diameter for the taper bore is 63.5 mm.

What is the hub Interface size for shaft accommodation?

The hub diameter measures 108 mm for hub-related clearances.

What pitch diameter determines chain engagement geometry?

The pitch diameter is 273.1 mm, which sets the chain path and centre distances.

What is the overall sprocket face width for chain contact?

The sprocket width across the teeth engagement area is 45 mm.
