1/2 in. Hex ID Sealed Bearing (R82RS-Hex)

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.

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 CIM Sport is a competition tested high performance line of planetary gearboxes from AndyMark and BaneBots. The CIM Sport features numerous improvements over previous planetary gearboxes used on FIRST Robotics Competition robots. 

Whether you have shafts that are too short or shafts of different types, this coupling will solve every component connection issue you've had! Need to combine multiple hex shafts, multiple 1/2-inch keyed shafts, or convert between hex and keyed? This coupling solves all at a better price than anyone else can offer!

Shaft Compatability

This coupling has geometry to capture 0.50-inch hex shafts with an inside hex of 0.51 to 0.52 inches as well as 0.5 inch keyed shafts with a 1/8th inch keyway with a keyway width of 0.128 inches to 0.131 inches.

These aluminum box extrusions are robust and lightweight solutions for custom robot frames, superstructures and mechanism construction. Made to all of your favorite English sizes, the classic 2x1 thin wall tubing is now joined by its thicker-walled counterpart. We have also introduced two thicknesses of 1x1 sizes that teams know and love to build their medium-sized mechanisms. 

For smaller mechanisms, we recommend using our 5/8 square box tube that is also compatible with our S3 line of brackets and gussets.

Available Sizes:

• 2 x 1 x 1/16 in. (0.063 in.) 6061-T6 alloy
• 2 x 1 x 1/8 in. (0.125 in.) 6061-T6 alloy
• 1 x 1 x 1/16 in. (0.063 in.)6061-T6 alloy
• 1 x 1 x 1/8 in. (0.125 in.)6061-T6 alloy
• 5/8 x 5/8 x 1/16 in. (0.063 in.) 6061-T6 alloy
• All lengths are (+/- 1in)

Be sure to all check out our Gussets as they work wonderfully with all of these wonderful extrusions.
