25 Series Symmetrical Hub Sprockets 500Hex, 14 Tooth

This collar clamp is a one-piece shaft collar with a 1/2 in. bore, 0.984 in. OD, and 0.236 in. width. The thin line design reduces weight and allows for use in confined spaces. It has the clamp style benefits of not marring the shaft, easy removability, and indefinite adjustability while commonly being used for guiding, spacing, stopping, mounting, and component alignment.

Specifications:

• Material: 2024 Aluminum
• Bore: 0.500 in.
• Outside Diameter: 0.984 in.
• Thickness: 0.236 in.
• Weight: 0.017 Pounds
• Clamping Screws: M2 5x8 SHCS

Each hub now has a "flower" pattern that fits and keys into our 42T 5 mm HTD Pulley, which means you are no longer constrained to our legacy 500EX Hex Hub for compatibility with this pulley. Every hub still maintains a closed-profile hole for maximum strength. Every shaft hub has been designed with bearing bosses on both sides that have been sized appropriately for the mating bearings that would pair with the bore through the hub, which means you can run each hub right against a bearing with no need for extra spacers. All of these hubs are also made from 7075-T6 aluminum, which is much stronger than the previously used 6061-T6, 6005, and 6105 alloys from our older designs. Where possible, the shoulder on shaft hubs was reduced to 7/8" in diameter for an easier fit with our molded plastic wheels, while still maintaining a precise 1.125" diameter boss for locating in wheels, sprockets, gears, and more. 

The holes are evenly spaced on a 1.875 in. circle and 0.201 inches in diameter. That's a perfect size for #10 bolts!

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.

9 different offerings of our 25 Series Hub Sprockets. These are perfect for meshing with roller chain and finally getting that-thing-that-you-need-to-spin moving!

These aluminum sprockets work perfectly with 1/2 in. hex shaft and mesh with #25 roller chain. They are symmetrical and have the same sized hub on both sides so there's no wrong way to install them. The hub is also sized to ride on only the inner race of a bearing for smooth motion without binding or rubbing.

Note: Despite the prints, at this time, tooth alignment to the bore is not controlled on these sprockets.

Specifications

• Chain Series: 25
• Material: 7075 Aluminum
• Thickness: 0.500 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.

8 different offerings of our 25 Series Plate Sprockets. These are perfect for meshing with roller chain and finally getting that-thing-that-you-need-to-spin moving!

These aluminum sprockets work perfectly with any of our 6 hole hubs and mesh with #25 roller chain.  They also work with other build systems that use a 2 in. bolt circle for mounting. The larger versions also have a mounting pattern compatible with 2x1 box tube usefull for making arms.

FTC Note: This product is NOT legal for FTC, we recommend our Stealth Wheel.

Product Overview: 
This is a 6" diameter wheel with a polycarbonate body and a TPU rubber "HiGrip" tread profile. This wheel features a 77A durometer tread material that is durable with long-life wear characteristics. Use this wheel for great tread life and good drivetrain response. 

We feel that these wheels are a more durable option for teams' drivetrains. While they provide good traction, they make for a maintenance-free wheel for the average team. Under normal circumstances we feel that these wheels will last most FIRST Robotics Competition teams the entire season. 
No bearings or hubs are included in this wheel. 

Specifications:

• Diameter: 6 inches
• Body Material: Polycarbonate, black
• Tread Material: TPU rubber, 77a durometer
• Bore: 0.95 inch, with bearing pockets of 1.124 inch diameter x 0.25 inch deep on both sides
• Weight: 0.5 pound
• Bolt Pattern: six holes (0.17 inch diameter) on a 1.875 inch diameter bolt circle
• Coefficient of friction: 0.95-1.0 static (on tight pile carpet)
• Coefficient of friction on HDPE: 0.31
• Side Load: In excess of 600 lbs at tread surface
• Load capacity: 90 pounds

Usage: 

• Use #10-24x3/4 thread forming screws to attach sprockets or hubs to this wheel. 

With Axle and Hub:

• If you wish to drive this wheel with an Axle and Hub, you can pick your hub by fitting any of the AndyMark hubs (not included) to this wheel. If this is your choice, then no bearing is needed. Use #10-24x3/4 thread forming screws to fasten a hub to this wheel.

With Sprocket:

• If you wish to drive this wheel with a sprocket, then the sprocket needs to be attached to the side of the wheel, and two ball bearingsneed to be pressed into the wheel (one on each side). The ball bearing must have a 1.125" od. For a 1/2" id, use am-0181 or am-0029. For a 3/8" id, use am-0209. Use #10-24x3/4 thread forming screws to fasten the sprocket to the wheel.

With Bearings:

• To press bearings into this wheel (for a free spinning wheel or for use with a sprocket), two ball bearings need to be pressed into the wheel (one on each side). The ball bearing must have a 1.125" od. For a 1/2" id, use am-0181 or am-0029. For a 3/8" id, use am-0209.

This simple bracket handles so many of your mounting needs! Mount motors or gearboxes anywhere and make axle supports with bearings - it's a do-it-all, put-it-anywhere bearing and motor mount bracket.

Any motor or gearbox with a 2-inch diameter bolt circle can be mounted in this bracket. The center hole is sized to hold a standard 1.125 inch outside diameter bearing.
