Aluminum Round Groove Pulley

Coral (also known as Game Piece 1) is a 11 ⅞ in. long (~30 cm) piece of 4 in. diameter Schedule 40 Cellular (Foam) Core PVC pipe. Coral has a 4-in. (~102 mm) inside diameter and a 4½-in. (~11 cm) outside diameter. The Coral sold here is from the same batch and manufacturer used on official fields. 

The Grasshopper nut, produced with the help of James Cole-Henry from FRC team 95, The Grasshoppers, is an innovative battery solution to increase the reliability of battery terminal connections.

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

These connecting chain attachment links, also known as K-links, are perfect for securing components that need movement, to a chain. These versions were specifically designed by AndyMark to interface with common FRC and FTC products. The #35 chain version is designed for #10 hardware on a 1 on. hole spacing. The #25 chain version is designed for #6 hardware with 16 mm (5/8 in.) hole spacing. Both versions make it much easier to interface chain to elevator systems than ever before. They can also be used in conveyor systems to move items around inside your robot.

The 25 Series Plate Sprockets: They roll! They turn! They spin! Everything you could possibly want from a plate sprocket.

These Aluminum sprockets work perfectly with hex shaft and mesh with #25 roller chain.

These game pieces are used in the 2024-2025 FIRST Tech Challenge game, INTO THE DEEP℠ presented by RTX. There are 20 Red Samples, 20 Blue Samples, 40 Neutral Samples, and 40 Clips are included in a Full field. 

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

Do you need an odd number of chain links? Tired of dealing with cotter pins in old school "half links"?  Love using the DarkSoul or ARC chain tool for everything? These are the links for you!

These links add one and a half links to a run of chain making for easier cleaner alternative to half links. Use a chain splicing tool or two master links to install them. No more lost matches from a failed half link!

• Chain Size: #25, #35
• Material: Steel
• Pitch: 0.25 in., 0.375 in.
• Style: Roller Chain
