    AndyMark 70 Tooth 9 mm Wide 5 mm Pitch HTD Timing Belt

    These are all of our 9 mm wide 5 mm pitch HTD synchronous timing belt offerings. All of these belts are a composite of flexible rubber with a fiberglass tensile member throughout. Synchronous timing belts, also known as a toothed belt or synchronous belt, are designed to eliminate slippage and keep any number of objects rotating at a constant rate. We offer genuine Gates brand belts, AndyMark branded belts, as well as lower-cost generic brand belts.

    2" Compliant Wheel, 1/2 inch Hex, 40 Durometer Orange

    #am-3462_orange
    $8.00
    (110 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.

    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

    1/2 in. Hex Collar Clamps, Silver Thin (0.25in) - 1 part

    #am-1635
    $6.95
    (39 In stock)

    These custom designed collar clamps have been designed specifically with FIRST Robotics Competition teams in mind. The one-piece collar clamp is a nice fractional 1/2 in. width to make shaft stackups easy. The clamping force is provided by a 10-32 socket head screw, which is bigger than most used in the competition marketplace.  This provides a high-strength clamping solution that shouldn't strip out when you need it most. You can even replace the 10-32 screw if it becomes lost with the screws historically used in the AM14U family of chassis. These thoughtfully designed collar clamps also have small bosses on each side. This allows these collar clamps to be installed directly adjacent to an FR8ZZ Round or FR8ZZ Hex bearing without rubbing on the outer races for smooth operation.
