Product Description

Sprocket 12B-2 z=26, hardened hub

Duplex sprocket 12B-2 with hardened hub, 26 teeth - dedicated to a chain with a pitch of 3/4" (19.05 mm). 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

Does Ozdowski have its own warehouse and fast shipping of parts?

Yes - we know that every minute counts during a production line breakdown, which is why we keep large stocks of sprockets available immediately, allowing lightning-fast shipping and a quick solution to the drive problem.

How does uneven tooth wear affect machine vibration?

Worn teeth cause the so-called polygon effect - the chain drops off and climbs onto the teeth abruptly, which transmits vibrations to the shafts, destroys the bearings and leads to cracking of welds in the machine.

What should be used to preserve sprockets before a longer break in operation?

After cleaning with a brush and a technical cleaner, apply preservative grease or a thick, moisture-displacing spray oil to the entire surface of the sprocket. This will protect the carbon steel against a rusty film during a break in the workshop.

Is a duplex sprocket the same as a tandem sprocket (for two single chains)?

No, even though they look very similar. A tandem sprocket is also a single, monolithic sprocket, but with a different (wider) spacing of the toothed rims - designed specifically for two independent simplex chains running in parallel. This duplex sprocket has a rim spacing matched to a single duplex chain, in which both strands are integrated with each other. Using a duplex sprocket for two single chains is a mistake - the spacing is too narrow and the chains will rub against each other, which leads to accelerated wear and, in extreme cases, to serious drive failure.

Where is this product used?

This type of sprocket is used in drives of agricultural and industrial machinery, including screw and bucket conveyors, feed conveyors, packaging machines and internal transport systems.
