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-1 (80-1) z=11 plate wheel.
How does the number of teeth affect the drive ratio?
The ratio is the number of teeth of the driven wheel divided by the number of teeth of the driving wheel. If this sprocket drives a wheel with twice as many teeth, the driven shaft turns twice as slowly but with roughly twice the torque.
Why does the sprocket have a pilot bore and how is it machined?
The pilot bore of Ø16 mm is left on purpose so that it can be bored precisely to the machine shaft size. The sprocket is clamped in a lathe by the outer edge of the hub to avoid run-out, and the bore is usually machined to H7 tolerance. The maximum bore diameter depends on the hub diameter (61 mm).
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.
