FAQ

Q: Can a slightly worn sprocket keep working?
A: It may be monitored for a short time if teeth are not hooked and no chain jump occurs. Replace it once hooked teeth appear, otherwise chain drop is highly likely.

Q: Should sprocket and chain be replaced together?
A: Pair replacement is recommended. Worn elongated chain will abrade new sprocket rapidly, and old sprocket accelerates wear of new chain.

Q: What should be noticed for key and keyway during installation?
A: Remove burrs and ensure tight fit of flat key. Never strike tooth surface; apply force only on hub to avoid tooth damage.

Q: What are typical symptoms of failed sprocket?
A: Periodic noise, frequent chain jumping and shaking. In severe cases the chain breaks and material feeding stops.
