Product Description

Sprocket 24B-2 (1 1/2") z=13 with hub, C45 steel fits 24B-2 roller chain (European standard DIN 8187 / ISO 606), double-strand (duplex), with a pitch of 38.1 mm (1 1/2"). It has 13 teeth and is made of C45 steel.

The sprocket has a one-sided hub with a diameter of 114 mm and a pilot bore of Ø25 mm, which is bored to the shaft size and completed with a keyway or a set screw hole. The total width of the sprocket is 100 mm.

Technical data

Applications

It is found in transmissions of industrial machinery that transfer high torque. The double-strand version carries higher loads than a single-strand one of the same pitch.

Frequently asked questions

Which chain does the 24B-2 z=13 sprocket fit?

24B-2 roller chain to European standard DIN 8187 / ISO 606, with a pitch of 38.1 mm. A duplex sprocket requires a double-strand (duplex) 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 a keyway cut in the hub?

The keyway is made to DIN 6885, keeping it aligned and with the correct width and depth so that the key sits firmly. The key should fit accurately - play in the keyway accelerates wear and, under shock loads, can lead to the key shearing off.

What is the set screw hole in the hub for?

The threaded hole, usually made above the keyway or at 90° to it, takes a headless set screw. It prevents the sprocket from sliding along the shaft when the machine vibrates.

Can a sprocket with hub be welded to the shaft?

Technically it is possible, but we do not recommend it. Welding overheats the material, can bend the shaft and damage nearby bearings, and makes later replacement of a worn sprocket very difficult. It is better to fix the sprocket with a key.

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.
