Sprocket 16B-2 z=46 with hub, hardened

Product Description

Sprocket 16B-2 z=46, hardened hub

The sprocket 16B-2 presented here is a duplex sprocket with 46 teeth, made with a hardened hub, for a chain with a pitch of 1" / 25.4 mm. Compliance with DIN 8187 / ISO 606 guarantees full interchangeability with chain of the same pitch; C45E steel (EN 10083-1) and induction hardening of the teeth (45-55 HRC) provide high wear resistance while keeping the hub machinable.

Technical data

Frequently asked questions

In what cases are multi-strand sprockets used?

They are used to drive multi-strand chains in heavily loaded machines where there is no room for a wider sprocket with a larger pitch. Several strands distribute the load evenly, preventing premature chain breakage.

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.

When is it worth using a clamping bush (Taper Bush) for a sprocket?

Wherever fast assembly matters. A clamping bush eliminates the need for laborious boring of the hub and cutting of a keyway - you insert the sprocket, tighten the screws and the machine is back in operation within minutes.

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?

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