SKF 11 Tooth Rough Stock Bore Sprocket, PHS 08B-2BH11 08 B-2

This sprocket is a steel transmission component designed to engage roller chains in industrial power-transfer systems. It provides rotary motion transfer between shafts and chain drives where a Compact 11-tooth configuration is required, and is supplied with a rough stock bore for bespoke fitting in workshop or maintenance settings.

• Eleven teeth provide Compact torque transmission for short centres
• Accepts 08 B-2 chain to match common roller chain profiles
• Steel construction offers high load-bearing capacity for continuous use
• EN and BS approvals support installation in regulated industrial environments
• Maximum inside diameter of 21 mm permits clearance for various shaft sizes

• Suitable for conveyor drive segments with tight geometry
• Used with single-strand industrial roller chain systems
• Ideal for retrofitting worn small-diameter chain drives
• Can be used for maintenance replacements in plant machinery
• Suitable for drives requiring a 35 mm wide engagement face

A rough stock bore is provided so the hub can be reamed or bored to the final shaft tolerance by the installer.

The hub diameter is 32 mm which offers a solid seating surface for keyways, shrink fits or press‑fit attachments as required.

The sprocket is designed for 08B-2 chain to ensure compatible tooth engagement and pitch matching.

The pitch diameter measures 45.07 mm which determines the effective chain pitch circle for alignment.
