Frequently asked questions
Which chain does this sprocket fit?
12B-1 roller chain to European standard DIN 8187 / ISO 606, with a pitch of 19.05 mm. A simplex sprocket requires a single-strand (simplex) chain.
Does it fit ASA 60 chain?
No. ASA 60 chain (American standard) has the same pitch, but a different roller diameter (11.91 mm instead of 12.07 mm) and a different inner width (12.7 mm instead of 11.68 mm). The 12B 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 12B-1 z=25 for Taper-Lock bush 2517 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 19.05 mm (3/4").
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 152 mm, and the outside diameter De is 160 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.
