    1/2" Churro, Red 3 FT /- 0.125" (am-3101-3_Red)

    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.

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

    #am-2986
    $8.00
    (87 In 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

    0.192 in. ID 0.375 in OD 1.0 in. Long Aluminum Spacer

    90 Degree Gusset

    #am-3860
    $5.00
    (44 In stock)

    We are pleased to offer these new gussets that are suitable for 1" based building systems. These thoughtfully designed gussets are made from 1/8" thick 6061-T6 aluminum, which is a much stronger material than other 0.09" 5052 gussets. All of these framing gussets feature a 1" linear hole pattern, with holes suitable for either #10 screws or 3/16" rivets.

     

    On all of the angle gussets, a generous radius was used on the inside corner for maximum strength. The various angle gussets, along with the quad and tee gusset are used together to create structures and sub-assemblies for your robot. Our bearing and Sport gussets are perfect building blocks to create a massive variety of mechanisms and assemblies to suit your needs.

     

    Specifications

    • Hole Pattern: Plates feature 0.20 in. Holes on a 1 in. Center to Center Spacing
    • Material: 6061-T6 Aluminum
    • Thickness: 0.125 in

    0.50 in. Hex and Keyed Shaft Coupling

    #AM-1560
    $25.00
    (15 In stock)

    Whether you have shafts that are too short or shafts of different types, this coupling will solve every component connection issue you've had! Need to combine multiple hex shafts, multiple 1/2-inch keyed shafts, or convert between hex and keyed? This coupling solves all at a better price than anyone else can offer!

    Shaft Compatability

    This coupling has geometry to capture 0.50-inch hex shafts with an inside hex of 0.51 to 0.52 inches as well as 0.5 inch keyed shafts with a 1/8th inch keyway with a keyway width of 0.128 inches to 0.131 inches.

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

    #am-3462_green
    $8.00
    (72 In 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.
