    Sliding Elevator Bearing Block Kit

    Note: The Sliding Elevator Bearing Block kit plates have been updated for 2024 to improve the ability to mount to grid pattern tubing. The threaded holes have also been changed to 1/4-20 to utilize a thicker bolt for the side bearings.

     

    Full kit weight: .75 pounds - 1 bearing block + hardware and bearings weighs 3 ounces.

     

    The Sliding Elevator Bearing Block Kit provides enough hardware to build up one stage of a sliding 2" x 1" box extrusion elevator.

     

    For every stage in your elevator's design, add another kit.

    1 stage elevator = 1 kit

    2 stage elevator + carriage = 2 kits

    Algae - Ball Game Piece 2 (Single)

    #am-5602
    $22.50

    Algae (also known as Game Piece 2) was available as a preorder for this season, and each team has received two of Game Piece 2 in the Season-Specific box from FIRST. Each Algae is a 16 in. (41 cm) ±½ in. (~12 mm) diameter rubber playground ball. While similar items are available from other sources, the only place to get the official Algae is in the Kit of Parts or from AndyMark. Algae are being offered as single items or in a box of 20, which is two more than a full field. 

    Algae will be inflated in accordance with the Algae Measuring Jig on competition fields. Ignore the instructions on the ball in favor of this jig for the most accurate Algae.

    Compliant Star 1/2 Hex 35A Durometer

    #am-5123_green
    $16.25
    ( 57 In stock)

    Compliant Stars are the perfect thing for intake mechanisms. The soft material gives way to allow rigid objects to be manipulated easily. A line of multiple stars on a driven hex shaft creates a very effective roller that ignores variations in the objects being driven. The multiple-spoke design allows the star to act as a brush, creating more surface area to interact with and grab objects. This makes for high-performance intakes and internal conveyors. A shaft collar may be used to make absolutely sure the wheels stay clear of other mechanisms or maintain consistent spacing. Molded into the star are several guidelines. Cut the star at the lines (or elsewhere) to create more compact mechanisms. 

     

     

    Different durometer ratings give each Compliant Star unique characteristics. Green stars (35A durometer) are the softest and most compliant around objects, while orange (40A), maroon (45A), and blue (50A) wheels are increasingly firm. Black (60A) is quite firm, while the Gray (80A) is nearly rigid. The increased firmness also allows the latter wheels to carry a higher RPM rating

    6" HiGrip Rubber Tread Wheel Rev2

    #am-0940b
    $18.45
    (In stock)

    FTC Note: This product is NOT legal for FTC, we recommend our Stealth Wheel.

    Product Overview: 
    This is a 6" diameter wheel with a polycarbonate body and a TPU rubber "HiGrip" tread profile. This wheel features a 77A durometer tread material that is durable with long-life wear characteristics. Use this wheel for great tread life and good drivetrain response. 

    We feel that these wheels are a more durable option for teams' drivetrains. While they provide good traction, they make for a maintenance-free wheel for the average team. Under normal circumstances we feel that these wheels will last most FIRST Robotics Competition teams the entire season. 
    No bearings or hubs are included in this wheel. 

    Specifications:

    • Diameter: 6 inches
    • Body Material: Polycarbonate, black
    • Tread Material: TPU rubber, 77a durometer
    • Bore: 0.95 inch, with bearing pockets of 1.124 inch diameter x 0.25 inch deep on both sides
    • Weight: 0.5 pound
    • Bolt Pattern: six holes (0.17 inch diameter) on a 1.875 inch diameter bolt circle
    • Coefficient of friction: 0.95-1.0 static (on tight pile carpet)
    • Coefficient of friction on HDPE: 0.31
    • Side Load: In excess of 600 lbs at tread surface
    • Load capacity: 90 pounds

    Usage: 

    • Use #10-24x3/4 thread forming screws to attach sprockets or hubs to this wheel. 


    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 bearingsneed 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.

    #am-3858
    $25.00
    ( 10 In stock)

    Looking to expand your robot battery cables? Well 4 AWG just may be the answer for you. The larger wire gauge provides less resistance and therefore can prolong your battery life. Just hooking up cable straight to a battery is not recommended, which is where this connector kit comes in. This SB120 Connector handles 48V and provides a quick connect and disconnect from battery to robot.

    $9.95
    ( 38 In stock)

    This is the same pulley used on the Thrifty Elevator Dyneema Pulley Kit. Works great with 1/8" dyneema rope and has a 1/4" ID bearing in the center allowing teams to use a bolt to easily mount it and have it spin freely.

     

    1.15" OD with a .365" groove will let this pulley work with other rope options as well.

    4" Compliant Wheel, 1/2" Hex Bore, 35A Durometer, Green

    #am-3480_green
    $14.50
    ( 51 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 axle creates a very effective roller that ignores variations in the objects being driven. This makes for high-performance intakes and internal conveyors.



    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), blue (50A), and black (60A) 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. 

     

      Please note maroon wheels are only intended for use in FTC. If more powerful motors are used to drive it the spokes may fail.
