SKF 9 Tooth Rough Stock Bore Sprocket, PHS 06B-1BH9 06 B-1

This sprocket is a simplex chain wheel designed to transmit rotary motion in power-transmission systems for industrial machinery. It suits single-strand roller chains and is supplied with a rough-machined bore and single-sided hub to allow final fitting to a shaft. Constructed in steel with a protective black oxide finish, it meets European standards for dimensional consistency.

• Hardened teeth improve wear resistance during cyclic operation
• Black oxide surface reduces corrosion and stray‑light reflections
• Compatible with 06 B‑1 chain for straightforward integration
• Rough bore allows custom finishing for precise shaft fit

• Suitable for conveyor drives in automation lines
• Ideal for timing drives in electrical assembly equipment
• Used with small transmission systems in robotics modules
• Can be used for retrofitting drives in control panels

The bore is supplied in a rough stock condition so final machining or broaching can be performed to achieve the required shaft tolerance and keyway geometry.

The steel construction combined with tooth hardening up to 25 teeth provides enhanced resistance to contact fatigue and abrasion under standard operating loads.

The single-sided hub gives a clear locating surface for axial positioning and simplifies machining operations when adapting the part to various shaft diameters.
