SKF Sprocket, 19 Teeth, 40mm Bore Size - PHS 08B-1BH19


This sprocket is a single‑row chain wheel designed to transmit rotary motion in industrial drive systems. Manufactured in steel with a protective black-oxide finish, it is intended for use with 08 B‑1 roller chain and suits mechanical assemblies requiring a hub connection to a shaft.

Features & Benefits


• Hardened teeth on smaller sizes improve wear resistance
• Rough-stock bore enables on‑site final machining
• Single hub profile offers straightforward shaft coupling
• Conforms to BS standards for dimensional compatibility

**Applications**


• Suitable for conveyor drive systems in automation plants
• Ideal for power transmission on assembly-line equipment
• Used with 08 B‑1 roller chain in material-handling machinery
• Can be used for retrofit replacements in factory drives

What bore machining options are possible for this sprocket?


The rough-stock bore arrives undersized for precision finishing so users can ream or bore to a specific shaft fit, accommodating keyway or shrink-fit preparations.

How does the hub profile affect mounting choices?


The single hub on one face centralises the shaft connection and permits simple clamping or keyway retention while leaving the opposite face clear for adjacent components.

Which chain pitch and tooth count correspond to this wheel?


It matches the 12.7mm chain pitch and a 19-tooth configuration, making it compatible with standard 08‑series chain arrangements.

What surface treatment is applied and why is it useful?


A black-oxide finish is provided to offer Basic corrosion resistance and to limit fretting where the component interfaces with shafts and fasteners.
