Technical data

Frequently asked questions

How does one duplex sprocket differ from two independent simplex sprockets on a common shaft?

A duplex sprocket is a single, monolithic toothed rim serving a duplex chain, in which both strands are mechanically integrated in one component. Two independent simplex sprockets on a common shaft serve two completely separate simplex chains - these solutions are not interchangeable without changing the chain type.

How do I select a sprocket with bearing for a tensioning system?

An idler sprocket (with built-in bearing) is selected according to the pitch of the working chain and mounted on the slack side (not on the tight side). It is important that the bearing is protected against dust, especially in agricultural machinery.

Do a newly fitted chain and sprocket require running-in after installation?

After installation, it is worth running the drive for a while without full load, observing the smoothness of operation and the bearing temperature - this allows installation errors (e.g. misalignment) to be detected before full load is applied. The tooth profile of the sprocket itself does not require running-in if the sprocket and chain have matching pitch and are made in accordance with the standard.

What is the standard procedure for submitting a complaint about a sprocket?

It is advisable to contact customer service, providing the product code, order number, and a description and photos of the observed defect - this makes it possible to quickly assess whether the complaint is justified and to propose further steps.

Where is this product used?

12B-1 sprockets are used in industrial drive transmissions: conveyors, feeders, packaging machines and production lines where precise, repeatable torque transmission matters.
