Sprocket 16B-2 z=38 for Taper-Lock bush 3030, cast iron

Product Description

Sprocket 16B-2 z=38 for Taper-Lock bush 3030, cast iron works with 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 EN-GJL-250 cast iron.

The sprocket has a seat for a Taper-Lock 3030 clamping bush, so it can be mounted on the shaft without boring the hole or cutting a keyway in the sprocket - simply choose a 3030 bush with a bore that matches the shaft. The hub diameter is 160 mm and the total width of the sprocket is 76 mm. The bush is not included - the 3030 bush can be purchased separately from our range.

Technical data

Applications

It is designed for heavy-duty drives: aggregate conveyors, construction machinery and mining equipment. The double-strand version carries higher loads than a single-strand one of the same pitch. The cast iron design works well for large sprockets in reduction gears, where rigidity and vibration damping matter.

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 3020; Sprocket 16B-2 z=38 for Taper-Lock bush 3020 hardened.

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.

Does the bush connection need to be checked during operation?

Yes. After the first period of operation, and later during inspections, it is worth checking that the bush screws are tight. In drives operating at higher temperatures, a check after the first warm-up is especially important.

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.
