Sprocket 16B-2 z=38 for Taper-Lock bush 3020, C45 steel, hardened

Product Description

Sprocket 16B-2 z=38 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 38 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=38 for Taper-Lock bush 3030, cast iron; Sprocket 16B-2 z=38 for Taper-Lock bush 3020, C45 steel.

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.

How can run-out be avoided after mounting the bush?

Cleanliness of the shaft, the bush and the sprocket seat is crucial. Even a small chip between the bush taper and the sprocket causes run-out, which accelerates wear of the chain and bearings.

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.
