10B-2 finished bore sprockets work with duplex 10B-2 chain of 5/8" (15.875 mm) pitch to DIN 8187 / ISO 606. They have a machined bore and keyway, so you fit them without any machining.
10B-2 duplex finished bore sprockets - more power and no machining
A duplex chain transmits considerably more power than a simplex chain at the same sprocket diameter. A finished bore saves time and costs, which with a duplex sprocket - wider and heavier - would be higher than usual. The sprockets are made of C45 steel.

When is it worth moving from 10B-1 to 10B-2 chain?
When a simplex chain stretches quickly or breaks, and there is no room in the machine for a larger sprocket. Remember to replace both drive sprockets with duplex ones.
