Sprocket 24B-1 z=25 for Taper-Lock bush 3020

Product Description

Sprocket 24B-1 z=25 for Taper-Lock bush 3020 works with 24B-1 roller chain (European standard DIN 8187 / ISO 606), single-strand (simplex), with a pitch of 38.1 mm (1 1/2"). It has 25 teeth and is made of C45 steel.

The sprocket has a seat for a Taper-Lock 3020 clamping bush, so it can be mounted on the shaft without boring the hole or cutting a keyway in the sprocket - simply choose a 3020 bush with a bore that matches the shaft. The bush is not included - the 3020 bush can be purchased separately from our range.

Frequently asked questions

Which chain does this sprocket fit?

24B-1 roller chain to European standard DIN 8187 / ISO 606, with a pitch of 38.1 mm. A simplex sprocket requires a single-strand (simplex) chain.

Does it fit ASA 120 chain?

No. ASA 120 chain (American standard) has the same pitch, but a different roller diameter (22.22 mm instead of 25.4 mm). The 24B sprocket is designed for European-standard chain, so the two systems should not be mixed.

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 303.99 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.

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.

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.
