It is found in production lines, mixers and screw feeders. 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?

10B-3 roller chain to European standard DIN 8187 / ISO 606, with a pitch of 15.875 mm. A triplex sprocket requires a triple-strand (triplex) chain.

Does it fit ASA 50 chain?

No. ASA 50 chain (American standard) has the same pitch and roller diameter, but a different inner width (9.52 mm instead of 9.65 mm). The 10B sprocket is designed for European-standard chain, so the two systems should not be mixed.

Can a Taper-Lock bush be used on a shaft without a keyway?

The bush holds on the shaft by friction, but in drives transmitting high torque a key is an essential safeguard. Bushes with larger bores have a standard keyway to DIN 6885.

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.
