Frequently asked questions
Which chain does this sprocket fit?
ASA 80-1 (16A-1) roller chain with a pitch of 25.4 mm. A simplex sprocket requires a single-strand (simplex) chain.
Does it fit 16B chain?
No. 16B chain (European standard) has the same pitch and roller diameter, but a different inner width (17.02 mm instead of 15.88 mm). The ASA 80 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 16A-2 (80-2) z=20 with hub.
Can a sprocket with hub be welded to the shaft?
Technically it is possible, but we do not recommend it. Welding overheats the material, can bend the shaft and damage nearby bearings, and makes later replacement of a worn sprocket very difficult. It is better to fix the sprocket with a key.
How should sprockets be aligned during installation?
The driving and driven sprockets must lie in one plane. Alignment can be checked with a long steel straightedge placed against the sides of both wheels or with a laser alignment tool. Even a small misalignment wears the sides of the teeth and speeds up chain wear.
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.
