Frequently asked questions

Which chain does the 06B-1 z=45 sprocket fit?

06B-1 roller chain to European standard DIN 8187 / ISO 606, with a pitch of 9.525 mm. A simplex sprocket requires a single-strand (simplex) chain.

Does it fit ASA 35 chain?

No. ASA 35 chain (American standard) has the same pitch, but a different roller diameter (5.08 mm instead of 6.35 mm) and a different inner width (4.77 mm instead of 5.72 mm). The 06B sprocket is designed for European-standard chain, so the two systems should not be mixed.

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 9.525 mm (3/8").

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 136.54 mm, and the outside diameter De is 140.7 mm.

When should I choose a sprocket with hub and when a plate wheel?

A sprocket with hub is chosen when it transmits torque directly from the shaft via a key - the hub provides a longer contact surface with the shaft and a more stable fit. Plate wheels are used mainly when the wheel is fixed to an existing flange or drum, or when there is little space on the shaft.

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.
