Frequently asked questions

Which chain does this sprocket fit?

12B-1 roller chain to European standard DIN 8187 / ISO 606, with a pitch of 19.05 mm. A simplex sprocket requires a single-strand (simplex) chain.

Does it fit ASA 60 chain?

No. ASA 60 chain (American standard) has the same pitch, but a different roller diameter (11.91 mm instead of 12.07 mm) and a different inner width (12.7 mm instead of 11.68 mm). The 12B 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 12B-1 z=114 for Taper-Lock bush 2525.

How can run-out be avoided after mounting the bush?

Cleanliness of the shaft, the bush and the sprocket seat is crucial. Even a small chip between the bush taper and the sprocket causes run-out, which accelerates wear of the chain and bearings.

Does the bush connection need to be checked during operation?

Yes. After the first period of operation, and later during inspections, it is worth checking that the bush screws are tight. In drives operating at higher temperatures, a check after the first warm-up is especially important.

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.
