    #25 Chain Tensioner - QTY 1

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

    #am-3155_orange
    $9.00
    (13 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.
