    Sushi Roller Intake Wheels - 1/2 in. Hex, 40a (Orange)

    #am-4541_orange
    $6,00
    ( 4 En stock)

    The Sushi Roller Intake Wheels are an excellent choice for robot intakes, internal conveyors, feeder mechanisms, or anywhere you need a durable, compact and grippy roller. These rollers are made with a robust polycarbonate hex bore hub, so no external hub is necessary - just slide them onto a hex shaft, constrain them axially and you are good to go. Available in a range of durometers for a wide variety of applications, these cute little rollers are great for getting a grip on things!

    #25 Chain Tensioner - QTY 1

    #ELEV-DRIVE-007
    $21,72
    ( 16 En stock)

    This turnbuckle chain tensioner integrates directly with #25 chain. Using a chain tool, the custom 1/4-20 link bolts replace a chain link and have the pin pushed back through it to become part of the chain. Then simply twist the center coupler to tighten or loosen the chain and tighten the jam nuts once your chain tension is perfect.

     

    All parts are made of steel including the coupler and the custom chain link bolts are 1/4-20 thread for increased strength. One link bolt is left hand threaded and the other is right hand threaded, so take care not to mix them up if purchasing multiple sets.

     

    Material: Steel, all of it.

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

    #am-3462_green
    $9,50
    ( 99 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.

    2" Stealth Wheel, 1/2 Hex Bore, Orange, 40 Durometer (am-3155_orange)

    #am-3155_orange
    $9,00
    ( 46 En stock)

    The inside black portion of this wheel is made from molded polycarbonate plastic. The outer tread is TPU (Thermoplastic PolyUrethane). This robust but lightweight wheel provides good traction on carpet and soft tiles. Stealth wheels are the perfect drive wheel for smaller (<50 lb.) robots, or for intakes and other auxiliary robot mechanisms. These wheels are available in a variety of bores and durometers. 4 in. Stealth Wheels feature a 6 bolt pattern on a 1.875 in. bolt circle for mounting sprockets, hubs, and gears. Nub Bore Stealth Wheels feature a 4 bolt pattern on a 16 mm bolt circle found in most FIRST Tech Challenge building systems. The lower the durometer the softer the wheel is, this makes it wear away faster, but also makes it more grippy.

    Product Usage:
    Many thread locking materials are not compatible with polycarbonate and can eat away at the plastic. Be sure to check which adhesives are okay to use with this product.
