    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.

    MFR Part #: am-4779
    $19.00
    Availability: 42 in stock

    Note: Despite the prints, at this time, tooth alignment to the bore is not controlled on these sprockets.

    $5.00

    We are pleased to offer these new gussets that are suitable for 1" based building systems. These thoughtfully designed gussets are made from 1/8" thick 6061-T6 aluminum, which is a much stronger material than other 0.09" 5052 gussets. All of these framing gussets feature a 1" linear hole pattern, with holes suitable for either #10 screws or 3/16" rivets.

     

    On all of the angle gussets, a generous radius was used on the inside corner for maximum strength. The various angle gussets, along with the quad and tee gusset are used together to create structures and sub-assemblies for your robot. Our bearing and Sport gussets are perfect building blocks to create a massive variety of mechanisms and assemblies to suit your needs.
