Frequently asked questions

Which chain does this sprocket fit?

16B-3 roller chain to European standard DIN 8187 / ISO 606, with a pitch of 25.4 mm. A triplex sprocket requires a triple-strand (triplex) chain.

Does it fit ASA 80 chain?

No. ASA 80 chain (American standard) has the same pitch and roller diameter, but a different inner width (15.88 mm instead of 17.02 mm). The 16B sprocket is designed for European-standard chain, so the two systems should not be mixed.

Is this sprocket available in another version?

Yes. Also available: Sprocket 16B-3 z=25 for Taper-Lock bush 3535.

When does a sprocket need replacing?

When the teeth start to look like pointed shark fins or are clearly bent to one side. Running on such a profile quickly destroys even a new chain, so a worn sprocket must be replaced. Thanks to the Taper-Lock bush, replacement is quick.

Can a new chain be fitted on a worn sprocket?

This should not be done. A worn sprocket has a changed tooth profile, so a new chain runs unevenly and elongates quickly. The rule is: new chain - new sprockets.

What does the lead time depend on?

When ordering, please check the current stock level of this sprocket - the lead time depends on it and is clearly stated according to the quantity available in each warehouse. The stock level is shown above the product price and may vary depending on the warehouse.
