SKF 40 Tooth Pilot Sprocket, PHS 08B-1A40 08 B-1

This sprocket is a simplex plate wheel designed to transmit power between roller chain links in industrial drive systems. Manufactured to European standards, it suits continuous mechanical applications where compatibility with 08 B-1 chain is required and where a pilot-bored steel sprocket is preferred for precise shaft locating.

• 40 teeth provide consistent chain engagement and load distribution
• Pilot bore design ensures accurate axial positioning on shafts
• Black oxide finish reduces corrosion risk and surface friction
• Hardened teeth on small sizes improve wear resistance
• Manufactured to EN and BS standards for specification conformity

• Suitable for conveyor drive systems in automation lines
• Used with 08B roller chain in packaging machinery
• Ideal for power transmission in assembly-line conveyors
• Can be used for retrofitting drive trains requiring 16mm bore
• Used for mechanical drives in electrical control cabinets

The sprocket accepts a minimum bore of 16mm and is pilot-bored to locate precisely on a matching shaft diameter.

It is designed for use with 08 B-1 roller chain, matching the chain pitch and tooth profile for correct meshing.

The steel construction offers structural strength under cyclic loads and, where teeth are hardened on smaller sizes, increased resistance to surface wear.

Pitch diameter of 161.87mm and the 12.7mm pitch are the key geometric parameters to confirm meshing and centre-distance requirements.
