Frequently asked questions

Which chain does this sprocket fit?

ASA 25-1 (04A-1) roller chain with a pitch of 6.35 mm. The same chain is also designated 04C-1. A simplex sprocket requires a single-strand (simplex) chain.

Is this sprocket available in another version?

Yes. Also available: Sprocket 04A-1 (25-1) z=10 with hub.

What causes wear on the sides of the teeth?

Most often misaligned sprockets. The chain does not run straight and its plates rub against the sides of the teeth. In this case the sprockets must be realigned in one plane.

How do I check sprocket run-out after installation?

A dial indicator on a magnetic stand is used. Place the tip against the rim or side of the sprocket and turn the shaft, reading the deviations. Excessive run-out usually means a crooked bore or a damaged shaft.

How should a sprocket be protected before a longer machine standstill?

After cleaning with a brush and technical cleaner, coat the whole surface of the sprocket with preservative grease or thick spray oil that displaces moisture. This protects the C45 steel against corrosion during downtime, for example out of season.
