Sprocket 16B-2 z=8 with hub, hardened

Product Description

Sprocket 16B-2 z=8, hardened hub

The sprocket 16B-2 presented here is a duplex sprocket with 8 teeth, made with a hardened hub, for a chain with a pitch of 1" / 25.4 mm. The material is carbon steel C45E (EN 10083-1), and the teeth undergo induction hardening to 45-55 HRC - in accordance with DIN 8187 / ISO 606; the hub retains a lower core hardness, so it can be machined safely.

Technical data

Frequently asked questions

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.

What does the pitch of a sprocket mean and how can it be checked?

The pitch of a sprocket corresponds to the chain pitch - it is the theoretical distance between the centres of adjacent teeth on the pitch circle. The easiest way to check it is to place a section of matching chain on the sprocket - it should sit perfectly, without tension.

How do you correctly align sprockets during installation?

The driving and driven sprockets must be in one perfect line. You can use a long steel straightedge placed against the faces of both sprockets or a professional laser alignment tool. Even a slight angular deviation will quickly destroy the chain.

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.
