#25 Connecting Link for Roller Chain

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.

We are pleased to offer these new gussets that are suitable for 1" based building systems. These thoughtfully designed gussets are made from 1/8" thick 6061-T6 aluminum, which is a much stronger material than other 0.09" 5052 gussets. All of these framing gussets feature a 1" linear hole pattern, with holes suitable for either #10 screws or 3/16" rivets.

On all of the angle gussets, a generous radius was used on the inside corner for maximum strength. The various angle gussets, along with the quad and tee gusset are used together to create structures and sub-assemblies for your robot. Our bearing and Sport gussets are perfect building blocks to create a massive variety of mechanisms and assemblies to suit your needs.

Specifications

• Hole Pattern: Plates feature 0.20 in. Holes on a 1 in. Center to Center Spacing
• Material: 6061-T6 Aluminum
• Thickness: 0.125 in

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

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.

Specifications

• Bore: 0.375 in. Hex, 0.5 in. Hex, 5 mm Hex
• Color: Green, Black, Blue, Black
• Core Material: Polycarbonate
• Diameter: 3 in.
• Durometer: 35A (Green), 40A (Orange), 50A (Blue), 60A (Black)
• Tread Material: TPU
• Weight: 0.12 lbs
• Overall Width: 1 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.

• Diameter: 2 in.
• Durometer: 35A (Green), ⠀40A (Orange), ⠀45A (Maroon), ⠀50A (Blue), 60A (Black)

Don't see what you need?

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.

Specifications

• Inside Diameter: 0.375 in. Hex, 0.50 in. Hex, 5 mm Hex
• Length: 0.063 in., 0.125 in., 0.188 in., 0.250 in., 0.375 in., 0.50 in., 1.00 in.
• Material: Polycarbonate
• Outside Diameter: 0.787 in. Round
• Weight: Up to 0.014 lbs

These custom designed collar clamps have been designed specifically with FIRST Robotics Competition teams in mind. The one-piece collar clamp is a nice fractional 1/2 in. width to make shaft stackups easy. The clamping force is provided by a 10-32 socket head screw, which is bigger than most used in the competition marketplace.  This provides a high-strength clamping solution that shouldn't strip out when you need it most. You can even replace the 10-32 screw if it becomes lost with the screws historically used in the AM14U family of chassis. These thoughtfully designed collar clamps also have small bosses on each side. This allows these collar clamps to be installed directly adjacent to an FR8ZZ Round or FR8ZZ Hex bearing without rubbing on the outer races for smooth operation.
