Frequently asked questions

Which chain does the 16B-1 z=25 sprocket fit?

16B-1 roller chain to European standard DIN 8187 / ISO 606, with a pitch of 25.4 mm. A simplex sprocket requires a single-strand (simplex) chain.

Which shaft does this sprocket fit?

The sprocket has a finished bore of 28 mm with a keyway, so it is mounted on a 28 mm shaft with a key. Before ordering, it is worth measuring the shaft carefully with a caliper in several places.

Does it fit ASA 80 chain?

No. ASA 80 chain (American standard) has the same pitch and roller diameter, but a different inner width (15.88 mm instead of 17.02 mm). The 16B sprocket is designed for European-standard chain, so the two systems should not be mixed.

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.

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.
