05B-1 simplex hub sprockets

05B-1 hub sprockets are simplex sprockets for 05B-1 chain of 8 mm pitch to DIN 8187 / ISO 606. They let you build both a drive with a ratio close to 1:1 and a large speed reduction in a single stage.

05B-1 simplex hub sprockets - a wide choice of ratios

A wide choice of tooth counts makes it easy to select the ratio without compromise. You bore out the pilot bore for your shaft and add a keyway or a tapped hole for a set screw, and C45 steel provides durability with easy machining.

05B-1 hub sprockets in C45 steel with unhardened teeth

05B-1 simplex hub sprockets in C45 steel, with unhardened teeth, from small driving sprockets to large driven sprockets. Hub and pilot bore dimensions are given on the product page, and duplex sprockets can be found in the neighbouring subgroup.

05B-1 sprocket vs 05B-2 chain - frequently asked questions

Will a 05B-1 sprocket work with 05B-2 chain?

No. A duplex chain needs a sprocket with two tooth rims - you will find them in the Duplex (double-row) subgroup.
