Frequently asked questions

Which chain does this sprocket fit?

ASA 120-1 (24A-1) roller chain with a pitch of 38.1 mm. A simplex sprocket requires a single-strand (simplex) chain.

Can a new chain be fitted on a worn sprocket?

This should not be done. A worn sprocket has a changed tooth profile, so a new chain runs unevenly and elongates quickly. The rule is: new chain - new sprockets.

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.

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.
