25 Series Symmetrical Hub Sprockets: 26 Tooth, 1/2 Hex

9 different offerings of our 25 Series Hub Sprockets. These are perfect for meshing with roller chain and finally getting that-thing-that-you-need-to-spin moving!

These aluminum sprockets work perfectly with 1/2 in. hex shaft and mesh with #25 roller chain. They are symmetrical and have the same sized hub on both sides so there's no wrong way to install them. The hub is also sized to ride on only the inner race of a bearing for smooth motion without binding or rubbing.
