Sprocket 12B-2 z=16 for Taper-Lock bush 1610

Product Description

Sprocket 12B-2 z=16 for Taper-Lock bush 1610 works with 12B-2 roller chain (European standard DIN 8187 / ISO 606), double-strand (duplex), with a pitch of 19.05 mm (3/4"). It has 16 teeth and is made of C45 steel.

The sprocket has a seat for a Taper-Lock 1610 clamping bush, so it can be mounted on the shaft without boring the hole or cutting a keyway in the sprocket - simply choose a 1610 bush with a bore that matches the shaft. The total width of the sprocket is 30.3 mm. The bush is not included - the 1610 bush can be purchased separately from our range.

Frequently asked questions

Which chain does this sprocket fit?

12B-2 roller chain to European standard DIN 8187 / ISO 606, with a pitch of 19.05 mm. A duplex sprocket requires a double-strand (duplex) 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 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.

Can a new chain be fitted on a worn sprocket?

This should not be done. A worn sprocket has a changed tooth profile, so a new chain runs unevenly and elongates quickly. The rule is: new chain - new sprockets.

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.
