Technical data

Applications

It works well in drives of conveyors, packaging machines and production lines where the sprocket has to be replaced quickly. The triple-strand version is chosen for very heavily loaded drives where there is no room for a chain with a larger pitch.

Frequently asked questions

Which chain does this sprocket fit?

08B-3 roller chain to European standard DIN 8187 / ISO 606, with a pitch of 12.7 mm. A triplex sprocket requires a triple-strand (triplex) chain.

Does it fit ASA 40 chain?

No. ASA 40 chain (American standard) has the same pitch, but a different roller diameter (7.94 mm instead of 8.51 mm) and a different inner width (7.94 mm instead of 7.75 mm). The 08B sprocket is designed for European-standard chain, so the two systems should not be mixed.

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.

Can a Taper-Lock bush be reused?

Yes, if it has not been mechanically damaged. Easy dismounting and remounting is one of the main advantages of this system.

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.
