Technical data

Frequently asked questions

Can a new chain be fitted on an old, worn sprocket?

Never do this. An old, deformed sprocket has altered tooth geometry and will force drastic mechanical stretching on the new chain. The rule is "new chain - new sprocket" - only then will the drive achieve maximum service life.

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.

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.

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.

Where is this product used?

Typical applications of the 12B-1 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.
