    2" Compliant Wheel, 1/2 inch Hex, 35 Durometer Green

    (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 shaft creates a very effective roller that ignores variations in the objects being driven. This makes for high-performance intakes and internal conveyors. The wheels are sized for an interference fit and tend to stay in place on a shaft, though a shaft collar may be used to make absolutely sure the wheels stay clear of other mechanisms or maintain consistent spacing.


    The hex bore versions of this wheel are undersized, and are intended to be an interference fit on their respective hex shafts. This interference fit allows for effective torque transfer from the hex shaft to the wheel, as well as allowing the wheel to remain in place along the shaft without the need for spacers or collar clamps:


    Compliant Wheel Sizing


    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), and blue (50A) 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.

    • Material: 6061 Aluminum
    • Bore: 0.501-505" hex bore (broached)
    • Bolt Pattern: 0.204" diameter holes, evenly spaced on a 1.875" diameter bolt circle
    • Boss diameter: 0.956" - 0.96"
    • Outside diameter: 2.25"
    • Weight: 0.104 pounds

    The mounting holes and the hex bore are now aligned and consistent.

    0.375 in. ID 0.5 in. OD Aluminum Spacer at Various Lengths (1.1875 in)


    This spacer is designed to fit on a shaft or screw that is 0.375 in. in diameter. Spacers help keep things in place in a multitude of ways. You can use this to slip over a shaft that is smaller than the inside diameter, between objects where it gets smashed between them with other fasteners, or help center a shaft of smaller size into a larger hole. Not seeing the length you're looking for? Consider stacking several together.




    • Inside Diameter: 0.375 in.
    • Length: 0.5 in.
    • Material: Aluminum
    • Outside Diameter: 0.5 in.

    Entrapption Star .5 Inch Hex Shaft

    (29 En stock)

    Our Entrapption Stars have two bore options, making them viable parts for both FRC and FTC! This product is frequently used as intake wheels for picking up game pieces. Made from silicone, they are flexible, yet firm, allowing for the ability to pick up objects of irregular shape.

    The 1/2 in. Hex Bore option is designed to be an interference fit on any 0.5 in. Hex Shaft.  This means the bore is actually 0.425 in. and it will be a tight press on, but keep the entrapption star from rotating.

    775 RedLine Motor

    (En stock)

    This updated version of the AndyMark 775 RedLine Motor is an even faster and more powerful version of this popular 775-class motor platform. With a power rating of up to 382W, this motor is capable of delivering even more immense power in the same small lightweight package over the previous version. This ball-bearing supported, air cooled motor is best used in high-speed applications where the motor will not be stalled for long periods such as shooters, conveyors, and intake mechanisms. With sufficient care and attention to your application's traction limit, this motor can be effective in FRC drive applications as well.


    Product Usage:

    Motors need air flow to keep cool. A hot motor won't last nearly as long, or deliver the power it once did new. To keep a RedLine cool and in great shape, use a 775 Vent Plate Spacer, am-3650 when mounting to a custom gearbox. All of our gearboxes that use this motor have vent plate spacers included with your purchase or include sufficient venting machined in.
