SKF Sprocket, 18 Teeth, 73.14mm Pitch Diameter - PHS 08B-1BH18

This sprocket is a steel transmission wheel designed to engage an 08 B-1 roller chain in industrial drive systems. It provides tooth engagement and power transfer for single-strand chain arrangements and is suitable for retrofit or replacement tasks in mechanical and automation assemblies.

Features and Benefits:

• 18 teeth ensure consistent chain engagement and smooth indexing
• 73.14mm pitch diameter maintains accurate chain pitch alignment
• Steel construction offers high-strength load handling for drives
• Rough stock bore accommodates 12mm–35mm shaft sizing
• 56mm hub diameter supports robust mounting and hub stability
• 28mm width gives lateral support for single-strand chains

Applications

• Suitable for conveyor drive assemblies using 08 B-1 chain
• Ideal for motor-to-gearbox coupling in automation cells
• Used with single-strand roller chain in material handling
• Can be used for replacement in industrial machinery maintenance
• Used for power transmission in electrical drive systems

What shaft sizes can it fit without additional machining?

The bore accepts shafts from 12mm to 35mm when finished to required fit tolerances.

Which chain form does it mate with directly?

It is designed to engage an 08 B-1 single-strand roller chain with the correct pitch and roller profile.

How does the hub design affect mounting options?

The 56mm hub diameter provides a stable contact surface for clamping or keyway installation, reducing the risk of eccentricity.

What application constraint should be considered regarding width?

The 28mm sprocket width is intended for single-strand use and may not be suitable for multi-strand arrangements.
