Sprocket 32B-3 (2") z=18 with hub, steel fits 32B-3 roller chain (European standard DIN 8187 / ISO 606), triple-strand (triplex), with a pitch of 50.8 mm (2"). It has 18 teeth and is made of structural steel.

The sprocket has a one-sided hub with a diameter of 180 mm, welded to the plate, and a pilot bore of Ø30 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 180 mm.

Technical data

Applications

It is used in sawmills, cement plants and bulk material handling lines. The triple-strand version is chosen for very heavily loaded drives where there is no room for a chain with a larger pitch.

Frequently asked questions

Which chain does the 32B-3 z=18 sprocket fit?

32B-3 roller chain to European standard DIN 8187 / ISO 606, with a pitch of 50.8 mm. A triplex sprocket requires a triple-strand (triplex) chain.

Does it fit ASA 160 chain?

No. ASA 160 chain (American standard) has the same pitch, but a different roller diameter (28.58 mm instead of 29.21 mm) and a different inner width (31.75 mm instead of 30.99 mm). The 32B 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?

It should be replaced 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.

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.
