05B-2 duplex hub sprockets

05B-2 hub sprockets have two tooth rims and work with duplex 05B-2 chain of 8 mm pitch to DIN 8187 / ISO 606. A duplex chain transmits more torque than a simplex chain, while the sprocket stays small and light.

05B-2 duplex hub sprockets - strengthening an overloaded drive

This is the simplest way to strengthen an overloaded 05B drive without rebuilding the machine for a larger-pitch chain. You bore out the pilot bore for your shaft, and C45 steel copes well with loads and is easy to machine.

05B-2 hub sprockets in C45 steel in a wide choice

05B-2 duplex hub sprockets in C45 steel, with unhardened teeth, in a wide choice of tooth counts. Hub dimensions and sprocket width are given on the product page, and simplex sprockets can be found in the neighbouring subgroup.

Two 05B-1 chains on a 05B-2 sprocket - questions and answers

Can a 05B-2 sprocket be driven by two 05B-1 chains?

No. The tooth rim spacing matches the strand spacing of 05B-2 chain, while two separate simplex chains need a different spacing.
