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.

Is this sprocket available in another version?

Yes. Also available: Sprocket 16B-3 z=57 for Taper-Lock bush 4040, cast iron.

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

Remove the mounting screws and screw one of them into the free dismounting hole. The screw then acts as a puller and pushes the bush out of the sprocket seat.

Can a Taper-Lock bush be used on a shaft without a keyway?

The bush holds on the shaft by friction, but in drives transmitting high torque a key is an essential safeguard. Bushes with larger bores have a standard keyway to DIN 6885.
