Applications
It is found in woodworking machinery, industrial gate drives and winches. The double-strand version carries higher loads than a single-strand one of the same pitch, so it is chosen where there is no room for a chain with a larger pitch.
Frequently asked questions
Which chain does this sprocket fit?
ASA 40-2 (08A-2) roller chain with a pitch of 12.7 mm. A duplex sprocket requires a double-strand (duplex) chain.
Does it fit 08B chain?
No. 08B chain (European standard) has the same pitch, but a different roller diameter (8.51 mm instead of 7.94 mm) and a different inner width (7.75 mm instead of 7.94 mm). The ASA 40 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 08A-1 (40-1) z=19 with hub.
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.
When are double-strand sprockets used?
Double-strand sprockets work with double-strand chains in heavily loaded drives where there is no room for a chain with a larger pitch. The two strands share the load evenly, which reduces wear and the risk of chain breakage.
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.
