Sprocket 32B-2 (2") z=45 with hub, steel

Product Description

Sprocket 32B-2 (2") z=45 with hub, steel fits 32B-2 roller chain (European standard DIN 8187 / ISO 606), double-strand (duplex), with a pitch of 50.8 mm (2"). It has 45 teeth and is made of structural steel.

The sprocket has a one-sided hub with a diameter of 220 mm, welded to the plate, and a pilot bore of Ø40 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 148 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 32B-2 z=45 sprocket fit?

32B-2 roller chain to European standard DIN 8187 / ISO 606, with a pitch of 50.8 mm. A duplex sprocket requires a double-strand (duplex) 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.

When are multi-strand sprockets used?

Double- and triple-strand sprockets work with multi-strand chains in heavily loaded drives where there is no room for a chain with a larger pitch. Several strands share the load evenly, which reduces wear and the risk of chain breakage.

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 50.8 mm (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 728.24 mm, and the outside diameter De is 751 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.
