    4" Stealth Wheel, 1/2 Hex Bore, Orange,40A Durometer (am-2647_orange)

    #am-2647_orange
    $12.00
    (70 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.

    24 Tooth 0.5 in. Hex Bore 5 mm HTD 18 mm Wide Aluminum Pulley

    #am-4626
    $19.00

    This robust 5mm HTD 18mm wide aluminum pulley is a lightweight motion component thoughtfully designed specifically for FIRST Robotics Competition robots. It features a lightweight 2024 aluminum core, made from our 24 Tooth Aluminum Pulley Stock. Unlike other products on the market, this pulley uses super strong steel flanges that are formed onto the pulley body instead of using a traditional press fit or crimps for maximum flange retention and durability. This pulley has small bosses on each side that allow them to be installed against an FR8ZZ Round or FR8ZZ Hex bearing without rubbing on the outer races for smooth operation. 

    This version of the pulley supports either two 9mm wide belts or one 15mm wide belt
