    4" HiGrip Wheel, 50A Durometer Blue

    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

    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.

    #10-24x3/4 Thread Forming Screw Minimum Qty 10

    (In stock)

    This is a Trilobe, thread forming, or thread rolling screw, ideal for applications where the screw is being threaded into plastic or metal. 

    A flat washer is part of the 5/16 hex head, providing more surface area contact than a regular hex head. The increased bearing area decreases the likeliness of crushing mating surfaces. Trilobe, or Thread Rolling, screws have a blunt tapered point that requires a pre-drilled or punched hole; eliminates chips and permits replacement with standard screw. Zinc plating froms a zinc carbonate film that greatly retards the corrosion rate in a normal atmosphere, which is similar to the aluminum oxide film that forms on aluminum that accounts for its low corrosion rate. 

    Product Overview:

    • Quantity: 50
    • Diameter: #10
    • Finish: Zinc
    • Head: 5/16 Hex with integral washer
    • Thread Length: 3/4"
    • Material: Steel
    • Thread Size: 10-24
    • Thread Type: Trilobe, Thread Rolling
    • Weight per Screw: 0.007 lbs
    • Package Weight: 0.34 lbs

    Andymark Hubs 1/2 in. Hex

    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!

    AndyMark 775 RedLine Motor with 16 Tooth 57 Sport Pinion Gear Installed

    #am-3775a_16t
    $42.00
    (In stock)

    This updated version of the AndyMark 775 RedLine Motor is an even faster and more powerful version of this popular 775-class motor platform. With a power rating of up to 363W, this motor is capable of delivering even more immense power in the same small lightweight package over the previous version. This ball-bearing supported, air cooled motor is best used in high-speed applications where the motor will not be stalled for long periods such as shooters, conveyors, and intake mechanisms. With sufficient care and attention to your application's traction limit, this motor can be effective in FRC drive applications as well.


    This variation of the RedLine comes with a 16 tooth, 0.7 Module pinion and mounting screws (am-3768) already installed allowing this motor to be installed into either a 57 Sport or a Dual 775 Sport gearbox. Not only does this take the risk of damaging the motor during pinion installation out of your hands, it also means that this counts as a COTS part in FRC.
