Sprocket 12B-3 z=15 with hub, hardened

Product Description

Sprocket 12B-3 z=15, hardened hub

Sprocket 12B-3 (pitch 3/4" - 19.05 mm), triplex, 15 teeth, with hardened hub. Sprocket compliant with DIN 8187 / ISO 606, milled from C45E steel (EN 10083-1); the teeth are induction hardened (45-55 HRC), while the core and hub remain soft, allowing the bore to be safely machined to the shaft size.

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.

What is the relationship between the number of teeth of a sprocket and the rotational speed of the drive?

This is the basic principle of the transmission ratio. If there is a small sprocket on the motor (drive) and a large one on the machine, the machine will turn more slowly but gain proportionally greater torque (force).

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 triplex sprocket the same as a tandem sprocket (for three single chains)?

No, even though they look very similar. A tandem sprocket is also a single, one-piece sprocket, but with a different (wider) spacing of the toothed rims - designed for independent simplex chains running in parallel. This triplex sprocket has a rim spacing matched to a single triplex chain in which all three strands are integrated with each other. Using a triplex sprocket for three single chains is a mistake - the spacing is too narrow, 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 12B-3 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.
