Sprocket 12B-3 (3/4") z=62 plate wheel, C45 steel

Product Description

Sprocket 12B-3 (3/4") z=62 plate wheel, C45 steel works with 12B-3 roller chain (European standard DIN 8187 / ISO 606), triple-strand (triplex), with a pitch of 19.05 mm (3/4"). It has 62 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 used in agricultural machinery, including seed drills, spreaders and grain conveyors. The triple-strand version is chosen for very heavily loaded drives 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 the 12B-3 z=62 sprocket fit?

12B-3 roller chain to European standard DIN 8187 / ISO 606, with a pitch of 19.05 mm. A triplex sprocket requires a triple-strand (triplex) chain.

Does it fit ASA 60 chain?

No. ASA 60 chain (American standard) has the same pitch, but a different roller diameter (11.91 mm instead of 12.07 mm) and a different inner width (12.7 mm instead of 11.68 mm). The 12B sprocket is designed for European-standard chain, so the two systems should not be mixed.

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.

When does a sprocket need replacing?

It should be replaced when the teeth start to look like pointed shark fins or are clearly bent to one side. Running on such a profile quickly destroys even a new chain, so a worn sprocket must be replaced.

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.
