Product Description

Sprocket 08B-1 (1/2") z=16 with hub, bore 24 mm with keyway, C45 steel works with 08B-1 roller chain (European standard DIN 8187 / ISO 606), single-strand (simplex), with a pitch of 12.7 mm (1/2"). It has 16 teeth and is made of C45 steel.

The sprocket has a hub with a finished bore of 24 mm and a keyway, so it can be fitted straight onto a shaft of this diameter - without boring the hole or cutting a keyway. The hub diameter is 50 mm and the total width of the sprocket is 28 mm.

Frequently asked questions

Which chain does the 08B-1 z=16 sprocket fit?

08B-1 roller chain to European standard DIN 8187 / ISO 606, with a pitch of 12.7 mm. A simplex sprocket requires a single-strand (simplex) chain.

Which shaft does this sprocket fit?

The sprocket has a finished bore of 24 mm with a keyway, so it is mounted on a 24 mm shaft with a key. Before ordering, it is worth measuring the shaft carefully with a caliper in several places.

Does it fit ASA 40 chain?

No. ASA 40 chain (American standard) has the same pitch, but a different roller diameter (7.94 mm instead of 8.51 mm) and a different inner width (7.94 mm instead of 7.75 mm). The 08B sprocket is designed for European-standard chain, so the two systems should not be mixed.

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 65.10 mm, and the outside diameter De is 69.5 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.
