Product Description

Sprocket 08B-1 z=41, hardened hub

Sprocket 08B-1 (pitch 1/2" - 12.7 mm), simplex, 41 teeth, with hardened hub. Made in accordance with DIN 8187 / ISO 606, from C45E steel (EN 10083-1), with teeth induction hardened to 45-55 HRC - as a Polish manufacturer, Ozdowski ensures that the hub remains soft and suitable for turning.

Technical data

Frequently asked questions

Can a new chain be fitted on an old, worn sprocket?

Never do this. An old, deformed sprocket has altered tooth geometry and will force drastic mechanical stretching on the new chain. The rule is "new chain - new sprocket" - only then will the drive achieve maximum service life.

Why are cast sprockets less precise than turned and milled ones?

Cheap castings have a rough tooth surface, hidden air bubbles and slight deformations. CNC-turned and milled sprockets mean a smooth working surface, perfect alignment and safety for the most expensive machines.

Can a sprocket be welded directly to the drive shaft?

Technically this is possible, but we strongly advise against such a solution. Welding overheats the material, damages nearby bearings, bends the shaft and prevents the worn sprocket from being easily replaced later. Always use mounting with a key or a clamping bush.

What material is this sprocket made of?

As standard, it is carbon steel C45E (EN 10083-1) - a good material for typical industrial applications, providing a good balance between strength and machinability of the hub.

Where is this product used?

Applications include drives in the food industry, packaging machines, sorting lines and agricultural harvesting machines, where the sprocket operates seasonally but under full load.
