Product Description

Sprocket 16B-3 z=38 for Taper-Lock bush 3535, cast iron is designed for 16B-3 roller chain (European standard DIN 8187 / ISO 606), triple-strand (triplex), with a pitch of 25.4 mm (1"). It has 38 teeth and is made of EN-GJL-250 cast iron.

The sprocket has a seat for a Taper-Lock 3535 clamping bush, so it can be mounted on the shaft without boring the hole or cutting a keyway in the sprocket - simply choose a 3535 bush with a bore that matches the shaft. The hub diameter is 178 mm and the total width of the sprocket is 89 mm. The bush is not included - the 3535 bush can be purchased separately from our range.

Technical data

Applications

It works in drives of lifts, winches and heavy chain conveyors. The triple-strand version is chosen for very heavily loaded drives where there is no room for a chain with a larger pitch. The cast iron design works well for large sprockets in reduction gears, where rigidity and vibration damping matter.

Frequently asked questions

Which chain does this sprocket fit?

16B-3 roller chain to European standard DIN 8187 / ISO 606, with a pitch of 25.4 mm. A triplex sprocket requires a triple-strand (triplex) chain.

Does it fit ASA 80 chain?

No. ASA 80 chain (American standard) has the same pitch and roller diameter, but a different inner width (15.88 mm instead of 17.02 mm). The 16B 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 16B-3 z=38 for Taper-Lock bush 3525; Sprocket 16B-3 z=38 for Taper-Lock bush 3525 hardened.

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 25.4 mm (1").

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 307.59 mm, and the outside diameter De is 320 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.
