The Sushi Roller Intake Wheels are an excellent choice for robot intakes, internal conveyors, feeder mechanisms, or anywhere you need a durable, compact and grippy roller. These rollers are made with a robust polycarbonate hex bore hub, so no external hub is necessary - just slide them onto a hex shaft, constrain them axially and you are good to go. Available in a range of durometers for a wide variety of applications, these cute little rollers are great for getting a grip on things!

Specifications

• Bore: 0.5 in. Hex, 5 mm Hex, 0.375 in. Hex
• Core Material: Polycarbonate
• Diameter: 1 in.
• Durometer: 35A (Green), 40A (Orange), 50A (Blue), 60A (Black)
• Tread Material: TPU
• Weight: 0.022 lbs
• Width: 1 in.

This turnbuckle chain tensioner integrates directly with #25 chain. Using a chain tool, the custom 1/4-20 link bolts replace a chain link and have the pin pushed back through it to become part of the chain. Then simply twist the center coupler to tighten or loosen the chain and tighten the jam nuts once your chain tension is perfect.

All parts are made of steel including the coupler and the custom chain link bolts are 1/4-20 thread for increased strength. One link bolt is left hand threaded and the other is right hand threaded, so take care not to mix them up if purchasing multiple sets.

Material: Steel, all of it.

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.

The inside black portion of this wheel is made from molded polycarbonate plastic. The outer tread is TPU (Thermoplastic PolyUrethane). This robust but lightweight wheel provides good traction on carpet and soft tiles. Stealth wheels are the perfect drive wheel for smaller (<50 lb.) robots, or for intakes and other auxiliary robot mechanisms. These wheels are available in a variety of bores and durometers. 4 in. Stealth Wheels feature a 6 bolt pattern on a 1.875 in. bolt circle for mounting sprockets, hubs, and gears. Nub Bore Stealth Wheels feature a 4 bolt pattern on a 16 mm bolt circle found in most FIRST Tech Challenge building systems. The lower the durometer the softer the wheel is, this makes it wear away faster, but also makes it more grippy.

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.

These aluminum 5M HTD Pulleys work great for creating belt reductions directly off the motor. Use a 15mm wide belt or two 9mm wide belts as the inside pulley teeth are 18.5mm wide. Choose either 8mm keyed bore or spline bore depending on the motor type you're using.

This retainer clip is used to hold objects (such as gears) in place on shafts. 

Example: This product can be used to hold a gear onto a CIM motor shaft. 

Specification: 

• Material: Steel
• Inner Diameter: 8mm
• Outer Diameter: 15mm
• Weight: Less than 0.001 lbs

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.

A staple in any robotics team's shop - the 1/2" rounded hex shaft. This shaft allows you to drive hubs, pulleys and other 1/2" hex broached items while also fitting into a 13.75mm ID bearing with ease. This shaft comes in lengths of 36 inches so you can cut them down to the size you need.

Available in both 7075 (anodized black) or 6061 (not anodized) variants.

Includes a hole sized for #10 taps.
