Sprocket 085-1 (1/2") z=80 plate wheel, C45 steel

Product Description

Sprocket 085-1 (1/2") z=80 plate wheel, C45 steel works with 085-1 roller chain (European standard DIN 8187 / ISO 606), single-strand (simplex), with a pitch of 12.7 mm (1/2"). It has 80 teeth and is made of C45 steel.

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 works well in light drives: packaging machines, labelling machines and small conveyors. Plate wheels are often mounted on drums and flanges and in large reduction gears.

Frequently asked questions

Which chain does the 085-1 z=80 sprocket fit?

085-1 roller chain to European standard DIN 8187 / ISO 606, with a pitch of 12.7 mm. A simplex sprocket requires a single-strand (simplex) chain.

What is the difference between the 085-1 sprocket and the 08B-1 sprocket if they have the same pitch?

Both sprockets have a pitch of 12.7 mm (1/2"), but they are designed for different chains. The 085-1 chain has an inner width of 6.4 mm and a roller diameter of 7.75 mm, while the 08B-1 chain has an inner width of 7.75 mm and a roller diameter of 8.51 mm. That is why the 085-1 sprocket has a narrower toothed rim (5.9 mm instead of 7.2 mm) and should not be used with 08B-1 chain, nor should these series be interchanged.

What causes wear on the sides of the teeth?

Most often misaligned sprockets. The chain does not run straight and its plates rub against the sides of the teeth. In this case the sprockets must be realigned in one plane.

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 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.
