Sprocket 16B-2 z=35 with hub, hardened

Product Description

Sprocket 16B-2 z=35, hardened hub

Sprocket 16B-2 (pitch 1" - 25.4 mm), duplex, 35 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

How does induction hardening of the teeth affect abrasion resistance?

Induction hardening hardens only the surface layer of the tooth, where the chain rollers bear. The tooth is resistant to wear, while the sprocket core and hub remain elastic enough to safely absorb impacts and be suitable for boring.

How does a hardness of around 45-55 HRC on the teeth extend the service life of the sprocket-chain system?

A hardness of 45-55 HRC matched to the hardened chain rollers is the optimal combination. The sprocket and chain wear slowly and evenly, and the sprocket does not turn into a "blade" that could shear the chain during operation.

How do I bore the hole in a sprocket to fit a motor shaft?

A sprocket with a pilot bore should be clamped in a lathe (gripping the hub to avoid runout) and bored to the required diameter with an H7 tolerance. If the sprocket has hardened teeth, the hub is usually soft and easy to machine.

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?

Typical applications of the 16B-2 sprocket: drives for pumps, mixers and industrial fans, as well as control systems for industrial gates and roller shutters, where resistance to continuous operation is required.
