The hub diameter is 87 mm and the total width of the sprocket is 32 mm. The bush is not included - the 2012 bush can be purchased separately from our range.

Technical data

Applications

It works well in drives of conveyors, packaging machines and production lines where the sprocket has to be replaced quickly. 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.

Can a Taper-Lock bush be reused?

Yes, if it has not been mechanically damaged. Easy dismounting and remounting is one of the main advantages of this system.

How do I check the pitch of a sprocket?

The sprocket pitch matches the chain pitch - it is the distance between the centres of adjacent teeth measured on the pitch circle. The easiest way to check it is to place a section of matching chain on the sprocket: it should sit on the teeth without tension. This sprocket has a pitch of 12.7 mm (1/2").

How is the pitch diameter of a sprocket calculated?

The pitch diameter Dp is the circle along which the chain rollers travel. It is calculated with the formula: pitch divided by the sine of (180° / number of teeth). For this sprocket it is 105.36 mm, and the outside diameter De is 110 mm.

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.
