    #TTB-0002
    $27.78
    ( 22 In stock)

    Tired of hex clamp collars that cost an arm and a leg? Tired of stripping out the set screw on your clamp collar? Need to add a collar in an assembly and don't want to remove everything from your hex shaft?

    Me too! I've ran into all of the above scenarios multiple times building multiple robots. These collars are the holy grail -

    • split so they can easily be added or removed
    • lightweight 6061 aluminum
    • .5 oz (.031 lbs) for one hex collar
    • uses two 8-32 socket head cap screws that require a 9/64" allen wrench
    • $4.00 per collar, sold in 5 packs
    • anodized black for awesomeness

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

    #am-4541_orange
    $6.00

    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!

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

    #am-3155_orange
    $9.00
    ( 46 In 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.

    #25 Chain Tensioner - QTY 1

    #ELEV-DRIVE-007
    $20.82
    ( 11 In 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.
