Frequently asked questions
Which chain does this sprocket fit?
ASA 60-1 (12A-1) roller chain with a pitch of 19.05 mm. A simplex sprocket requires a single-strand (simplex) chain.
Does it fit 12B chain?
No. 12B chain (European standard) has the same pitch, but a different roller diameter (12.07 mm instead of 11.91 mm) and a different inner width (11.68 mm instead of 12.7 mm). The ASA 60 sprocket is designed for American-standard chain, so the two systems should not be mixed.
Is this sprocket available in another version?
Yes. Also available: Sprocket 12A-2 (60-2) z=24 with hub.
How does tooth wear affect machine operation?
Worn teeth make the chain engage the sprocket unevenly and abruptly. This causes vibrations that are passed on to shafts and bearings and accelerate wear of the whole drive.
How do I check the pitch of a sprocket?
The sprocket pitch matches the chain pitch - it is the distance between the centres of adjacent teeth measured on the pitch circle. The easiest way to check it is to place a section of matching chain on the sprocket: it should sit on the teeth without tension. This sprocket has a pitch of 19.05 mm (3/4").
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.
