Frequently asked questions

Which chain does this sprocket fit?

16B-3 roller chain to European standard DIN 8187 / ISO 606, with a pitch of 25.4 mm. A triplex sprocket requires a triple-strand (triplex) chain.

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.

How do I choose the bush for this sprocket?

The sprocket has a seat for a Taper-Lock 3525 bush, so a bush with the same number is needed. It is chosen with a bore matching the shaft diameter - before ordering, it is worth measuring the shaft carefully with a caliper in several places.

What does bush number 3525 mean?

The four-digit number indicates the size of the bush. The last two digits give its width in tenths of an inch - the 3525 bush is 2.5 inch wide. The sprocket and the bush must have the same number.

How do I mount a sprocket with a Taper-Lock bush?

Insert the bush into the sprocket seat, align the holes and lightly screw in the screws. Then slide the assembly onto the shaft and tighten the screws alternately until the bush is firmly clamped on the shaft.

What does the lead time depend on?
