Technical data

Frequently asked questions

Do you offer sprockets made to custom dimensions, outside the catalogue?

Yes, in addition to catalogue items we also manufacture sprockets to individual drawings or customer requirements - please contact the sales department and provide the required parameters (pitch, number of teeth, hub dimensions, material).

How do I determine the centre distance between the driving and driven sprockets?

The centre distance should provide an adequate chain wrap angle on the smaller sprocket (usually a minimum of about 120°) and sufficient chain length so that the number of links is a whole number, preferably even. Too small a centre distance increases the meshing frequency and accelerates wear, while too large a one leads to excessive chain sag.

How can a sprocket and chain be protected against corrosion during storage?

After cleaning off any dirt, it is advisable to apply a layer of preservative grease or anti-corrosion oil and store the sprocket in a dry place not exposed to condensation. In the steel version (without coating), even a short damp break in the workshop can cause a rusty film on the tooth surfaces.

Can I replace a simplex sprocket with a duplex one without changing the other drive components?

No - switching to a duplex chain and sprocket requires replacing the entire set (the sprockets on both sides of the drive and the chain) with a duplex version of the same pitch, because the rim spacing and chain width differ from those of the simplex version.

Where is this product used?

Applications include drives in the food industry, packaging machines, sorting lines and agricultural harvesting machines, where the sprocket operates seasonally but under full load.
