This new custom designed collar clamp has been designed specifically with FIRST Robotics Competition teams in mind. This product is Out of Stock until Mid March

This robust 5mm HTD 9mm wide aluminum pulley is a lightweight motion component thoughtfully designed specifically for FIRST Robotics Competition robots. It features a lightweight 2024 aluminum core, made from our 24 Tooth Aluminum Pulley Stock. Unlike other products on the market, this pulley uses super strong steel flanges that are formed onto the pulley body instead of using a traditional press fit for maximum flange retention and durability. This pulley has small bosses on each side that allow them to be installed against an FR8ZZ Round or FR8ZZ Hex bearing without rubbing on the outer races for smooth operation. Much like our 17 Tooth Magic Sprocket, this pulley is designed to fit perfectly inside a 2" x 1" aluminum box tube between two FR8ZZ Hex Bearings.
 

This version of the pulley supports one 9mm wide belt.

Specifications

• Belt Profile: 5 mm pitch HTD timing belt
• Bore: 0.5 in. Hex
• Flange Diameter: 1.63 in.
• Material: Aluminum
• Outside Diameter: 1.46 in.
• Pitch Diameter: 1.504 in.
• Teeth: 24
• Weight: 0.074 lbs
• Width: 0.5 in.

This is a heavy-duty compression lug from BURNDY for 06 AWG wire. This compression log can be easily crimped with the PRO-CRIMP Crimp Tool (am-3326).

Specifications

• Gauge: 06 AWG
• Hole Size For Stud: 0.25 in.
• Material: Copper
• Overall Length: 2.03 in.
• Tongue Width: 0.48 in.
• Weight: 0.01 lbs
• Wire Strip Length: 1.18 in.

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!

A West Coast style drivetrain can be finicky to create without precision machining capabilities. This Bearing Block Kit makes it much more accessible for teams to create high performance West Coast Drive style platforms with limited fabrication resources. Simply drill a clearance hole for a shaft to pass through your drive rail, pull your chain or belt tight, and clamp it down with the included hardware. Featuring machined pockets to capture 10-32 Nylock Nuts, these blocks can be used and reused without worrying about damaging threads upon installation. Because each block is the same part, you can keep the screw heads pointing to the outside of your robot for easy maintenance. 

This unassembled kit ships with enough hardware to provide significant clamping pressure to help keep your powertrain components tensioned properly, and can withstand upwards of 1500lbs of force along the axis of the tube when properly installed. This means that for most FRC use cases, a team can install these without the need for tensioning devices to keep things aligned.

The AndyMark West Coast Drive Bearing Block Kit is designed to be used with flanged ball bearings with a 1.125" outer race, such as our FR8ZZ-HexHD Bearing.

The AndyMark West Coast Drive Bearing Block Kit also includes mounting geometry for components that utilize 2" and 1.875" bolt circles, such as motors, gearboxes, sprockets, hubs and gears. This makes this product great for many uses outside of your drivetrain, such as a robust interface to make a rotary arm, or an easy-to-use mounting interface for motors to power your mechanisms. The bearing plate is also 2" wide, making it perfect to keep two 20DP gears (of which the total teeth add up to 80,) meshed together.

• 2 - WCD Bearing Block (am-4560)
• 4 - 10-32 Nylock Nut (am-1042)
• 4 - 10-32 x 1.5in Socket Head Cap Screw (am-1014)

Specifications

• Block Height: 0.45 in.
• Block Length: 2.88 in.

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:

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. 

Specifications

• Bore: 1/2 in. Hex, 3/8 in. Hex, Nub Bore
• Diameter: 2 in.
• Durometer: 35A (Green), ⠀40A (Orange), ⠀45A (Maroon), ⠀50A (Blue), 60A (Black)
• Hole Pattern: Qty 2 3.5 mm Holes on a 16 mm Circle for 8 mm bore wheels
• Material: TPU
• Maximum RPM: 6000 - 9000
• Weight: 0.035 lb.
• Width: 0.5 in.

Churro is a versatile extruded aluminum hex profile. The outside of this part is a 1/2 in. hex with small concave dimples which act as weight savings. There is an inside hole is sized at 0.2 in. in order to fit 1/4-20 thread forming screws. No tapping or threading is needed, as long as a thread forming screw is used. The outside hex size fits a 1/2 in. wrench or socket. 

The 3-foot churro, our most popular length and the best value on shipping, is available anodized in red, blue, purple, gold and black to dress up your robot. Anodized finish is hardy and doesn't flake off or add thickness like paint, but it is possible for a scratch to expose the bare metal beneath. Take basic precautions in your shop like watching for sharp tools or overtightening this churro in a vise.

Specifications:

• Material: 6005A Aluminum
• Inside diameter: 0.231 in.
• Outside width: 0.495 in. Hex, across flats
• Length: Selectable Above
• Weight: 0.16 lbs/ft
