Frequently asked questions

Which chain does this sprocket fit?

ASA 35-1 (06A-1) roller chain with a pitch of 9.525 mm. The same chain is also designated 06C-1. A simplex sprocket requires a single-strand (simplex) chain.

Does it fit 06B chain?

No. 06B chain (European standard) has the same pitch, but a different roller diameter (6.35 mm instead of 5.08 mm) and a different inner width (5.72 mm instead of 4.77 mm). The ASA 35 sprocket is designed for American-standard chain, so the two systems should not be mixed.

How does the number of teeth affect the drive ratio?

The ratio is the number of teeth of the driven wheel divided by the number of teeth of the driving wheel. If this sprocket drives a wheel with twice as many teeth, the driven shaft turns twice as slowly but with roughly twice the torque.

Why does the sprocket have a pilot bore and how is it machined?

The pilot bore is left on purpose so that it can be bored precisely to the machine shaft size. The sprocket is clamped in a lathe by the outer edge of the hub to avoid run-out, and the bore is usually machined to H7 tolerance. The maximum bore diameter depends on the hub diameter.

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 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.
