Sprocket 08B-2 z=24 for Taper-Lock bush 2012, C45 steel

Product Description

Sprocket 08B-2 z=24 for Taper-Lock bush 2012, C45 steel works with 08B-2 roller chain (European standard DIN 8187 / ISO 606), double-strand (duplex), with a pitch of 12.7 mm (1/2"). It has 24 teeth and is made of C45 steel.

The sprocket has a seat for a Taper-Lock 2012 clamping bush, so it can be mounted on the shaft without boring the hole or cutting a keyway in the sprocket - simply choose a 2012 bush with a bore that matches the shaft. The bush is not included - the 2012 bush can be purchased separately from our range.

Technical data

Applications

It is found in agricultural machinery, workshop equipment and gate drives. The double-strand version carries higher loads than a single-strand one of the same pitch.

Frequently asked questions

Which chain does this sprocket fit?

08B-2 roller chain to European standard DIN 8187 / ISO 606, with a pitch of 12.7 mm. A duplex sprocket requires a double-strand (duplex) chain.

Does it fit ASA 40 chain?

No. ASA 40 chain (American standard) has the same pitch, but a different roller diameter (7.94 mm instead of 8.51 mm) and a different inner width (7.94 mm instead of 7.75 mm). The 08B 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?

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. Thanks to the Taper-Lock bush, replacement is quick.

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.
