SKF Sprocket, 30mm Bore Size, 21 Teeth - PHS 06B-1BH21

This sprocket is a single‑hub simplex component designed to transmit power in roller‑chain drives within industrial equipment. It mates with 06 B‑1 chain types and is produced to European EN and BS standards, offering a standardised sprocket solution for automation and mechanical drive systems.

Features & Benefits

• Hardened teeth on small sizes for extended wear life
• Rough stock bore allows custom machining to fit shafts
• Single‑side hub profile facilitates secure shaft connection
• High‑grade steel construction provides mechanical durability

Applications

• Suitable for conveyor drives in automated assembly lines
• Used with reduction stages in electromechanical systems
• Ideal for retrofitting industrial chain drives
• Used for replacement in maintenance of 06B-1 chain systems

What bore range can be finalised for shaft fitting?

The rough stock bore can be machined down to a minimum of 12mm or retained up to a maximum of 30mm to suit specific shaft diameters.

How does the hub profile assist installation?

The single‑side hub profile gives a clear mounting face for locating and securing to the shaft, simplifying alignment during assembly.

What surface protection is applied to the component?

A black oxide coating is applied to the steel to provide Basic corrosion resistance and a uniform appearance.
