Sprocket 28B-2 (1 3/4") z=29 plate wheel, C45 steel

Product Description

Sprocket 28B-2 (1 3/4") z=29 plate wheel, C45 steel fits 28B-2 roller chain (European standard DIN 8187 / ISO 606), double-strand (duplex), with a pitch of 44.45 mm (1 3/4"). It has 29 teeth and is made of C45 steel.

The plate wheel has a pilot bore of Ø30 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 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. Plate wheels are often mounted on drums and flanges and in large reduction gears.

Frequently asked questions

Which chain does the 28B-2 z=29 sprocket fit?

28B-2 roller chain to European standard DIN 8187 / ISO 606, with a pitch of 44.45 mm. A duplex sprocket requires a double-strand (duplex) chain.

Does it fit ASA 140 chain?

No. ASA 140 chain (American standard) has the same pitch, but a different roller diameter (25.4 mm instead of 27.94 mm) and a different inner width (25.4 mm instead of 30.99 mm). The 28B sprocket is designed for European-standard chain, so the two systems should not be mixed.

When should I choose a plate wheel and when a sprocket with hub?

A plate wheel is chosen when the wheel is fixed to an existing flange, drum or your own hub, or when there is little space on the shaft. A sprocket with hub works better where torque is transmitted directly from the shaft via a key.

How does the number of teeth affect the drive ratio?

The ratio is the number of teeth of the driven wheel divided by the number of teeth of the driving wheel. If this sprocket drives a wheel with twice as many teeth, the driven shaft turns twice as slowly but with roughly twice the torque.

How should sprockets be aligned during installation?

The driving and driven sprockets must lie in one plane. Alignment can be checked with a long steel straightedge placed against the sides of both wheels or with a laser alignment tool. Even a small misalignment wears the sides of the teeth and speeds up chain wear.

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.
