SKF 40 Tooth Taper Bush Sprocket, PHS 08B-1TB40 08 B-1

This sprocket is a steel transmission wheel designed to drive 08 B-1 roller chain in industrial power-transmission assemblies. It provides torque transfer between shafts where a taper-mounted hub and precision tooth form are required, and is suitable for continued operation in mechanical and automation equipment that relies on standardised chain engagement.

• Taper bush bore enables secure, removable hub mounting • 40 teeth deliver consistent chain engagement for steady speed ratios • 161.87mm pitch diameter ensures accurate centre-distance geometry • 32mm width supports stable chain tracking under load • 90mm hub diameter offers robust support for mounted shafts • Manufactured to BS and EN criteria for standardised interchangeability

• Suitable for conveyor drives in manufacturing automation • Ideal for sprocket-and-chain speed reduction in mechanical systems • Used with power transmission setups in electrical motor coupling • Can be used for replacement drives in industrial electronics enclosures • Suitable for retrofitting 08 B-1 chain installations requiring taper mounting

It uses a taper bush arrangement that clamps the bore to the shaft for concentric, removable attachment.

The 40-tooth configuration alters gear ratio and reduces runaway acceleration compared with fewer-tooth alternatives, aiding smoother speed control.

It is designed specifically for use with 08 B-1 roller chain profiles to ensure correct meshing and load distribution.

Constructed from steel, it offers wear resistance and dimensional stability for sustained engagement in power-transmission environments.
