Frequently asked questions
Which chain does this sprocket fit?
ASA 40-1 (08A-1) roller chain with a pitch of 12.7 mm. A simplex sprocket requires a single-strand (simplex) 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.
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.
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.
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.
