Sprocket 16B-1 (1") z=19 with hub, bore 42 mm with keyway, C45 steel

Product Description

Sprocket 16B-1 (1") z=19 with hub, bore 42 mm with keyway, C45 steel fits 16B-1 roller chain (European standard DIN 8187 / ISO 606), single-strand (simplex), with a pitch of 25.4 mm (1"). It has 19 teeth and is made of C45 steel.

The sprocket has a hub with a finished bore of 42 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 100 mm and the total width of the sprocket is 45 mm.

Frequently asked questions

Which chain does the 16B-1 z=19 sprocket fit?

16B-1 roller chain to European standard DIN 8187 / ISO 606, with a pitch of 25.4 mm. A simplex sprocket requires a single-strand (simplex) chain.

Which shaft does this sprocket fit?

The sprocket has a finished bore of 42 mm with a keyway, so it is mounted on a 42 mm shaft with a key. Before ordering, it is worth measuring the shaft carefully with a caliper in several places.

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.

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.

How does the number of teeth affect the drive ratio?

The ratio is the number of teeth of the driven wheel divided by the number of teeth of the driving wheel. If this sprocket drives a wheel with twice as many teeth, the driven shaft turns twice as slowly but with roughly twice the torque.

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.
