    Hex Molded Spacers, 1/2 Hex, 0.5 inch length

    Whether you are building an elite custom drivetrain or a championship manipulator, you need your components to stay where they're supposed to. These lightweight spacers come in 3/8", 1/2", and 5 mm hex bores to accommodate the most common shaft types They can also be used on round shafts and bolts (5mm is great for #10 hardware!). If you need to space a lot grab some 1" spacers. If you need ultimate precision pick up some 0.063" spacers. Not sure which spacers you need? Keep a handful of all six sizes in your shop and never go hungry for spacers again! 

     

    These spacers are molded in black polycarbonate, a tough, crack resistant material that FIRST teams are familiar with. These spacers should resist stress cracking. If polycarbonate isn't rugged enough for your high load application or you need custom length spacers, check out our Aluminum Hex Spacer Extrusion.

    6" SmoothGrip Wheel 80A Durometer Grey

    #am-0144a
    $18.00
    (En stock)

    Looking or a flat profile wheel with plenty of grip? Look no further than our six inch SmoothGrip wheels! Many are familiar with our flagship HiGrip wheels which feature an aggressive tread pattern great for biting hard into the ground. SmoothGrip wheels provide a strong level of traction with a longer life-span thanks to their smooth profile. They make great drive wheels on almost any surface as well as great flywheels to propel game pieces at high speed without damage. SmoothGrip wheels feature your favorite 1.125 in. bearing bore and 1.875 in. bolt circle, allowing you to mount a hub or bearing of your choice for live or dead axle setups.



    Please note, due to the way these wheels are molded the outer profile may be tapered slightly to one side, this does not significantly affect performance as a drive wheel in most applications.

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

    #am-3462_green
    $8.00
    (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.
