Sprocket 16B-2 z=21 for Taper-Lock bush 3020, C45 steel, hardened

Product Description

Sprocket 16B-2 z=21 for Taper-Lock bush 3020, C45 steel, hardened fits 16B-2 roller chain (European standard DIN 8187 / ISO 606), double-strand (duplex), with a pitch of 25.4 mm (1"). It has 21 teeth and is made of C45 steel. The sprocket is hardened, which increases the wear resistance of the teeth.

The sprocket has a seat for a Taper-Lock 3020 clamping bush, so it can be mounted on the shaft without boring the hole or cutting a keyway in the sprocket - simply choose a 3020 bush with a bore that matches the shaft. The bush is not included - the 3020 bush can be purchased separately from our range.

Frequently asked questions

Which chain does this sprocket fit?

16B-2 roller chain to European standard DIN 8187 / ISO 606, with a pitch of 25.4 mm. A duplex sprocket requires a double-strand (duplex) 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-2 z=21 for Taper-Lock bush 3020, C45 steel.

What does bush number 3020 mean?

The four-digit number indicates the size of the bush. The last two digits give its width in tenths of an inch - the 3020 bush is 2.0 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.
