SKF Sprocket, 38 Teeth, 115.35mm Pitch Diameter - PHS 06B-1B38

This sprocket is a toothed drive wheel designed to transmit power through a roller chain in industrial motion systems. Manufactured from steel, it is intended for use in mechanical assemblies where positive drive engagement with a 06 B-1 chain is required and conforms to recognised EN and BS standards for industrial components.

Features and Benefits:

• Compatible with 06 B-1 chain ensuring secure power transmission
• Thirty-eight teeth provide consistent engagement with chain links
• Hub diameter 70mm supports robust mounting to shafts
• Sprocket width 30mm allows stable lateral chain guidance
• Rough stock bore adaptable for bore machining between 14mm and 48mm

Applications

• Suitable for conveyor drive units in automation systems
• Ideal for timing and indexing mechanisms in electronics manufacture
• Used with reduction gearboxes in mechanical plant
• Can be used for retrofitting drives in electrical motor assemblies

What range of bore sizes can be finalised for shaft fitting?

The rough stock bore is supplied oversized to allow machining to any diameter within the 14mm to 48mm range so it can be tailored to the EXACT shaft tolerance.

How does the pitch diameter affect chain engagement?

The pitch diameter of 115.35mm determines the effective radius for chain wrapping and influences centre distance calculations and sprocket pair compatibility.

What material properties influence service life under load?

Constructed from steel, the component offers high strength and wear resistance suited to continuous duty and varying load cycles when correctly mounted.
