Product Description

Sprocket 24B-1 z=57 for Taper-Lock bush 4545, C45 steel, hardened is designed for 24B-1 roller chain (European standard DIN 8187 / ISO 606), single-strand (simplex), with a pitch of 38.1 mm (1 1/2"). It has 57 teeth and is made of C45 steel. The sprocket is hardened, which increases the wear resistance of the teeth.

The sprocket has a seat for a Taper-Lock 4545 clamping bush, so it can be mounted on the shaft without boring the hole or cutting a keyway in the sprocket - simply choose a 4545 bush with a bore that matches the shaft. The bush is not included - the 4545 bush can be purchased separately from our range.

Frequently asked questions

Which chain does this sprocket fit?

24B-1 roller chain to European standard DIN 8187 / ISO 606, with a pitch of 38.1 mm. A simplex sprocket requires a single-strand (simplex) chain.

Does it fit ASA 120 chain?

No. ASA 120 chain (American standard) has the same pitch, but a different roller diameter (22.22 mm instead of 25.4 mm). The 24B 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 24B-1 z=57 for Taper-Lock bush 3030, cast iron.

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.
