    2" Compliant Wheel, 1/2 inch Hex, 50 Durometer Blue

    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.

    Bearing, 1/2 inch Hex Bore, Flanged, (FR8ZZ-HexHD)

    #am-2986
    $8.00
    (87 En stock)

    This is a Heavy Duty Hex Bearing which outperforms our previous 1/2" Hex Bearings as it has a Heavy Duty Inner Race. This FR8ZZ-HexHD bearing, 1/2" hex bore, flanged, heavy duty inner race, shielded ball bearing, has an inner race that is thicker and stronger than our recent offering of a similar bearing (am-0279). This bearing has more material between the corners of the hex bore and the edge of the race making it stronger and much less likely to crack under high load.

    This bearing is guaranteed to have a stronger, thicker race. 100% of these bearings have been quality checked for a smooth fit over 1/2" hex stock here at AndyMark. Many of our long-time customers will recognize this bearing, as it is the same version we sold back in 2008-2011, and we did not have any failures. Now, it is renamed and quality checked for your high load needs - including drive chassis with cantilevered wheels.


    Specifications:

    • Inside diameter: 0.500-0.502 inch hex bore
    • Outside diameter: 1.125 inch
    • Flange thickness: 0.062 inch
    • Overall thickness: 0.312 inch
    • Weight: 0.05 pound

    6" HiGrip Wheel, 50A Durometer, Blue

    #am-0940b_Blue
    $18.45
    (En stock)

    HiGrip wheels provide superior traction for robot movement. HiGrip wheels feature an aggressive tread pattern providing maximum transfer of gearbox power to the ground. A robust polycarbonate core means these wheels are up to the challenge for high impact and speed applications. Varying durometers mean you can choose just how grippy these wheels can be. White or 77A durometer HiGrip wheels have a long life and provide good traction. Black or 60A durometer HiGrip wheels have an intermediate life and higher grip than white. Blue or 60A durometer HiGrip wheels provide the most traction and will wear quickly as a result. The bolt pattern and bore of these wheels allow for convenient bearing placement and easy attachment to other motion parts such as sprockets and pulleys. 

    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. This link will allow you to check which materials are okay to use with what adhesives, http://bit.ly/loctitematerialcheck

    Specifications:

    • Diameter: 4" or 6"
    • Body Material: Polycarbonate
    • Tread Material: Thermoplastic Polyurethane
    • Durometer: 77A (Grey), 60A (Black), 50A (Blue)
    • Bore: 0.95", with bearing pockets of 1.124" diameter x 0.25" deep on both sides
    • Bolt Circle: Six holes (0.17" diameter) on a 1.875" diameter bolt circle
    • 77A Carpet CoF: 0.95-1.0 Static
    • 60A Carpet CoF: 0.77 Static
    • 50A Carpet CoF: 0.97 Static
    • 4" Wheel Load Capacity: 100 Pounds
    • 6" Wheel Load Capacity: 90 Pounds

    Usage: 
    Use #10-24x3/4 thread forming screws to attach sprockets or hubs to this wheel. 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. This link will allow you to check which materials are okay to use with what adhesives, http://bit.ly/loctitematerialcheck

    With Axle and Hub:

    • If you wish to drive this wheel with an Axle and Hub, you can pick your hub by fitting any of the AndyMark hubs (not included) to this wheel. If this is your choice, then no bearing is needed. Use #10-24x3/4 thread forming screws to fasten a hub to this wheel.

    With Sprocket:

    • If you wish to drive this wheel with a sprocket, then the sprocket needs to be attached to the side of the wheel, and two ball bearings need to be pressed into the wheel (one on each side). The ball bearing must have a 1.125" od. For a 1/2" id, use am-0181 or am-0029. For a 3/8" id, use am-0209. Use #10-24x3/4 thread forming screws to fasten the sprocket to the wheel.

    With Bearings:

    • To press bearings into this wheel (for a free spinning wheel or for use with a sprocket), two ball bearings need to be pressed into the wheel (one on each side). The ball bearing must have a 1.125" od. For a 1/2" id, use am-0181 or am-0029. For a 3/8" id, use am-0209.

    #AM-3101-3_BLACK
    $25.00
    (0 En stock)

    Churro is a versatile extruded aluminum hex profile. The outside of this part is a 1/2 in. hex with small concave dimples which act as weight savings. There is an inside hole is sized at 0.2 in. in order to fit 1/4-20 thread forming screws. No tapping or threading is needed, as long as a thread forming screw is used. The outside hex size fits a 1/2 in. wrench or socket. 

    The 3-foot churro, our most popular length and the best value on shipping, is available anodized in red, blue, purple, gold and black to dress up your robot. Anodized finish is hardy and doesn't flake off or add thickness like paint, but it is possible for a scratch to expose the bare metal beneath. Take basic precautions in your shop like watching for sharp tools or overtightening this churro in a vise.

    Specifications:

    • Material: 6005A Aluminum
    • Inside diameter: 0.231 in.
    • Outside width: 0.495 in. Hex, across flats

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

    #am-2647_orange
    $12.00
    (40 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.
