Sprocket 08B-2 z=19 for Taper-Lock bush 1210

Product Description

Sprocket 08B-2 z=19 for Taper-Lock bush 1210 is designed for 08B-2 roller chain (European standard DIN 8187 / ISO 606), double-strand (duplex), with a pitch of 12.7 mm (1/2"). It has 19 teeth and is made of C45 steel.

The sprocket has a seat for a Taper-Lock 1210 clamping bush, so it can be mounted on the shaft without boring the hole or cutting a keyway in the sprocket - simply choose a 1210 bush with a bore that matches the shaft. The hub diameter is 62 mm and the total width of the sprocket is 25 mm. The bush is not included - the 1210 bush can be purchased separately from our range.

Technical data

Applications

It is used in industrial automation drives, feeders and food industry machinery. 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.

Is this sprocket available in another version?

Yes. Also available: Sprocket 08B-2 z=19 for Taper-Lock bush 1210 hardened.

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 77.16 mm, and the outside diameter De is 81.7 mm.

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.

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.
