QTY 1 - 36 Inch Long 1/2" Rounded Hex Shaft - 7075 Aluminum

Whether you are building an elite custom drivetrain or a championship manipulator, you need your components to stay where they're supposed to. These lightweight spacers come in 3/8", 1/2", and 5 mm hex bores to accommodate the most common shaft types They can also be used on round shafts and bolts (5mm is great for #10 hardware!). If you need to space a lot grab some 1" spacers. If you need ultimate precision pick up some 0.063" spacers. Not sure which spacers you need? Keep a handful of all six sizes in your shop and never go hungry for spacers again! 

These spacers are molded in black polycarbonate, a tough, crack resistant material that FIRST teams are familiar with. These spacers should resist stress cracking. If polycarbonate isn't rugged enough for your high load application or you need custom length spacers, check out our Aluminum Hex Spacer Extrusion.

You asked, we listened! These 3" diameter HD (heavy-duty) solid-core Compliant Wheels are intended for manipulating objects where you need a little 'give' in your intake system. These wheels deform out of the way to allow rigid objects to be manipulated easily. This makes for high-performance intakes and internal conveyors. These wheels do not require the use of expensive hubs to be driven, thanks to their integrated high strength polycarbonate hubs - which are made from the same mold that creates our Hex Molded Spacers.

Different durometer ratings give each wheel unique characteristics. Green compliant wheels (35A durometer) are the softest and most compliant around objects, while maroon (45A) blue (50A) and black (60A) wheels are increasingly firm.

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. 3 in. and 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.

This is a Heavy Duty Hex Bearing which outperforms our previous 1/2" Hex Bearings as it has a Heavy Duty Inner Race. This FR8ZZ-HexHD bearing, 1/2" hex bore, flanged, heavy duty inner race, shielded ball bearing, has an inner race that is thicker and stronger than our recent offering of a similar bearing (am-0279). This bearing has more material between the corners of the hex bore and the edge of the race making it stronger and much less likely to crack under high load.

This bearing is guaranteed to have a stronger, thicker race. 100% of these bearings have been quality checked for a smooth fit over 1/2" hex stock here at AndyMark. Many of our long-time customers will recognize this bearing, as it is the same version we sold back in 2008-2011, and we did not have any failures. Now, it is renamed and quality checked for your high load needs - including drive chassis with cantilevered wheels.

Specifications:

• Inside diameter: 0.500-0.502 inch hex bore
• Outside diameter: 1.125 inch
• Flange thickness: 0.062 inch
• Overall thickness: 0.312 inch
• Weight: 0.05 pound

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!
