24B Chain Sprockets

24B sprockets are the metric equivalent to ANSI 120. Though they have the same pitch, a 120 sprocket will not work with a 24B chain because of other slight dimensional differences. We supply standard stock-bore A, B, and C-Hub sprockets as well as taper bushed style. However, we also supply custom bored and custom configurations 24B sprockets from our in-house machining facility.
