    0.50 in. Hex and Keyed Shaft Coupling

    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, 60 Durometer Black

    #am-3462_black
    $8.00

    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 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
