Sprocket 16A-2 (80-2) z=30 plate wheel

Product Description

Sprocket 16A-2 (80-2) z=30 plate wheel works with ASA 80 (16A-2) roller chain, double-strand (duplex), with a pitch of 25.4 mm (1"). It is a plate wheel without a hub, has 30 teeth and is made of C45 steel in accordance with ISO 606 and ANSI B29.1.

The plate wheel has a pilot bore of Ø25 mm. It can be bolted or welded to your own hub, flange or drum, which makes it a good choice for larger ratios and non-standard designs.

Technical data

Applications

It is used in sawmills, cement plants and bulk material handling lines. The double-strand version carries higher loads than a single-strand one of the same pitch, so it is chosen where there is no room for a chain with a larger pitch. Plate wheels are often mounted on drums and flanges and in large reduction gears.

Frequently asked questions

Which chain does this sprocket fit?

ASA 80-2 (16A-2) roller chain with a pitch of 25.4 mm. A duplex sprocket requires a double-strand (duplex) chain.

Does it fit 16B chain?

No. 16B chain (European standard) has the same pitch and roller diameter, but a different inner width (17.02 mm instead of 15.88 mm). The ASA 80 sprocket is designed for American-standard chain, so the two systems should not be mixed.

How do I check sprocket run-out after installation?

A dial indicator on a magnetic stand is used. Place the tip against the rim or side of the sprocket and turn the shaft, reading the deviations. Excessive run-out usually means a crooked bore or a damaged shaft.

How should a sprocket be protected before a longer machine standstill?

After cleaning with a brush and technical cleaner, coat the whole surface of the sprocket with preservative grease or thick spray oil that displaces moisture. This protects the C45 steel against corrosion during downtime, for example out of season.

How does tooth wear affect machine operation?

Worn teeth make the chain engage the sprocket unevenly and abruptly. This causes vibrations that are passed on to shafts and bearings and accelerate wear of the whole drive.

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.
