Product Description
Sprocket 16B-2 z=38, hardened hub
Sprocket 16B-2, duplex, with 38 teeth and a hardened hub - pitch 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.

Frequently asked questions
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.
How do you cut a keyway in the hub of a sprocket?
We cut keyways precisely on slotting machines according to DIN 6885. If you do it yourself, maintain axial alignment and the correct width and depth of the keyway so that the key sits securely and is not sheared off.
When is it worth considering a sprocket made of reinforced steel for heavy-duty operating conditions?
In heavy dust, with powerful jolts (e.g. in presses) and where a breakdown in the middle of the season cannot be afforded, sprockets made of higher-strength quenched and tempered steel are often a good solution - it is worth consulting the supplier about unusual operating conditions.
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?
16B-2 sprockets are used in industrial drive transmissions: conveyors, feeders, packaging machines and production lines where precise, repeatable torque transmission matters.
