    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.

    4" Compliant Wheel, 1/2" Hex Bore, 35A Durometer, Green

    #am-3480_green
    $14.50
    (14 En stock)

    Compliant wheels are not intended for moving robots, but moving objects. Compliant wheels give way to allow rigid objects to be manipulated easily. A line of multiple wheels on a driven hex axle creates a very effective roller that ignores variations in the objects being driven. This makes for high-performance intakes and internal conveyors.



    Different durometer ratings give each wheel unique characteristics. Green wheels (35A durometer) are the softest and most compliant around objects, while orange (40A), maroon (45A), blue (50A), and black (60A) wheels are increasingly firm. The increased firmness also allows the latter wheels to carry a higher RPM rating. Check out the downloads tab for a chart showing wheels and their maximum RPM. 

     

    Please note maroon wheels are only intended for use in FTC. If more powerful motors are used to drive it the spokes may fail.

    24 Tooth 0.5 in. Hex Bore 5 mm HTD 18 mm Wide Aluminum Pulley

    #am-4626
    $19.00

    This robust 5mm HTD 18mm wide aluminum pulley is a lightweight motion component thoughtfully designed specifically for FIRST Robotics Competition robots. It features a lightweight 2024 aluminum core, made from our 24 Tooth Aluminum Pulley Stock. Unlike other products on the market, this pulley uses super strong steel flanges that are formed onto the pulley body instead of using a traditional press fit or crimps for maximum flange retention and durability. This pulley has small bosses on each side that allow them to be installed against an FR8ZZ Round or FR8ZZ Hex bearing without rubbing on the outer races for smooth operation. 

    This version of the pulley supports either two 9mm wide belts or one 15mm wide belt
