    Surface Mount 120 Amp Breaker by Eaton Bussmann

    A 120 Amp Circuit breaker legal for FIRST Robotics Competition robots.

     

    Used in many educational and competition robotics as a safety mechanism for over current.

     

    Of course, we highly recommend using circuit breakers on each channel downstream, rated appropriately for each component to protect your motors, speed controllers, and control system components. 

     

    The waterproof housing is meant to be surface mounted on a rigid element of a robot.

     

    Per R609 of the 2022 First Robotics Competition Manual this breaker, CB285-120 is legal for use in the First Robotics Competition.
    We have two FRC legal options, if this one is out of stock, please see am-0282

    2" Compliant Wheel, 3/8 inch Hex, 35 Durometer Green

    #am-3571_green
    $8.00 $10.42
    (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.

    SDS Billet Elevator Bearing Block Kits Single Corner

    #AM-5474
    $49.00
    ( 16 In stock)

    SDS Billet Bearing Blocks are the core of an incredibly efficient and smooth elevator mechanism.

     

    SDS Billet Elevator Bearing Blocks are designed to integrate with tube plugs and commonly available pre-drilled or punched 2x1 tubing. Attach 1 or 2 tube plugs to a bearing block depending on where it is used on an elevator. These allow the connection between the box tube and the Bearing Blocks to be primarily inside of the box tube, resulting in an incredibly low profile. 

     

    These premium bearings blocks utilize cam followers for the primary load direction. Cam followers are designed for the line contact loading present in FRC elevators and have a higher load rating when compared to similarly sized ball bearings. Cam followers also have a much larger face width than typical bearings, allowing for more overlap to prevent elevator stages from becoming dislodged.



    SDS bearing blocks come with 2 sets of spacers for the cam followers. Users can decide if they would like to use the long spacers for maximum bearing overlap, or the short spacers if needed for screw head clearance.

     

    Included Items:

    3 inch Compliant Wheel, 1/2 inch Hex, 35A Durometer, Green

    #am-3945_green
    $12.25
    ( 12 In stock)

    You asked, we listened! These 3" diameter HD (heavy-duty) solid-core Compliant Wheels are intended for manipulating objects where you need a little 'give' in your intake system. These wheels deform out of the way to allow rigid objects to be manipulated easily. This makes for high-performance intakes and internal conveyors. These wheels do not require the use of expensive hubs to be driven, thanks to their integrated high strength polycarbonate hubs - which are made from the same mold that creates our Hex Molded Spacers.



    Different durometer ratings give each wheel unique characteristics. Green compliant wheels (35A durometer) are the softest and most compliant around objects, while maroon (45A) blue (50A) and black (60A) wheels are increasingly firm.

     

    Specifications

     

    • Bore: 0.375 in. Hex, 0.5 in. Hex, 5 mm Hex
    • Color: Green, Black, Blue, Black
    • Core Material: Polycarbonate

    Andymark Hubs 1/2 in. Hex

    #am-4124
    $14.00
    (In stock)

    Each hub now has a "flower" pattern that fits and keys into our 42T 5 mm HTD Pulley, which means you are no longer constrained to our legacy 500EX Hex Hub for compatibility with this pulley. Every hub still maintains a closed-profile hole for maximum strength. Every shaft hub has been designed with bearing bosses on both sides that have been sized appropriately for the mating bearings that would pair with the bore through the hub, which means you can run each hub right against a bearing with no need for extra spacers. All of these hubs are also made from 7075-T6 aluminum, which is much stronger than the previously used 6061-T6, 6005, and 6105 alloys from our older designs. Where possible, the shoulder on shaft hubs was reduced to 7/8" in diameter for an easier fit with our molded plastic wheels, while still maintaining a precise 1.125" diameter boss for locating in wheels, sprockets, gears, and more. 

     

    The holes are evenly spaced on a 1.875 in. circle and 0.201 inches in diameter. That's a perfect size for #10 bolts!
