Applications
It is used in sawmills, cement plants and bulk material handling lines. 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 80-2 (16A-2) roller chain with a pitch of 25.4 mm. A duplex sprocket requires a double-strand (duplex) 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=15 with hub.
How is a keyway cut in the hub?
The keyway is made to DIN 6885, keeping it aligned and with the correct width and depth so that the key sits firmly. The key should fit accurately - play in the keyway accelerates wear and, under shock loads, can lead to the key shearing off.
What is the set screw hole in the hub for?
The threaded hole, usually made above the keyway or at 90° to it, takes a headless set screw. It prevents the sprocket from sliding along the shaft when the machine vibrates.
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.
