Technical data

Applications

It is designed for heavy-duty drives: aggregate conveyors, construction machinery and mining equipment. The triple-strand version is chosen for very heavily loaded drives where there is no room for a chain with a larger pitch. The cast iron design works well for large sprockets in reduction gears, where rigidity and vibration damping matter.

Frequently asked questions

Which chain does this sprocket fit?

24B-3 roller chain to European standard DIN 8187 / ISO 606, with a pitch of 38.1 mm. A triplex sprocket requires a triple-strand (triplex) 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.

When are multi-strand sprockets used?

Double- and triple-strand sprockets work with multi-strand chains in heavily loaded drives where there is no room for a chain with a larger pitch. Several strands share the load evenly, which reduces wear and the risk of chain breakage.

When is a sprocket for a Taper-Lock bush the right choice?

Wherever quick mounting and replacement matter. The clamping bush eliminates boring the hole and cutting a keyway in the sprocket - simply choose a bush with a bore that matches the shaft, seat it in the sprocket and tighten the screws.

How do I choose the bush for this sprocket?

The sprocket has a seat for a Taper-Lock 4545 bush, so a bush with the same number is needed. It is chosen with a bore matching the shaft diameter - before ordering, it is worth measuring the shaft carefully with a caliper in several places.

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.
