This 1/4-20 screw is 1 in. long. This screw is thread forming which means it creates a secure connection with the parts it attaches to without the use of a nut.
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 axle creates a very effective roller that ignores variations in the objects being driven. This makes for high-performance intakes and internal conveyors. Different durometer ratings give each wheel unique characteristics. Green wheels (35A durometer) are the softest and most compliant around objects, maroon (45A), blue (50A), and black (60A) 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.

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.
#25 Connecting Link (Master Link) Specifications:
1/2 in. hex shaft is the life of many competitive robot components. This 1018 steel shaft is available in four lengths. The five inch shaft was used in various Modulox gearboxes and may come with a 1/4 in. hole drilled in one end. The other sizes can be used as shaft stock, ready to be cut to length as needed. The stock lengths ship un-plated ready for your choice of finish.
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.
