25 Series Bearing Bore Plate Sprocket - 32 Tooth

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

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.

This Inline Chain Tensioner for #25 series roller chain is perfect to adjust the desired tension in a long run of chain on mechanisms such as elevators and arms. This is ideal where there is at least a ~3" section of chain that never passes over a sprocket in a given mechanism. Pair this with two #25 Master Links and integrate this to your project for an easy-to-use chain tension solution!

The design of this product was inspired by Misumi's Chain Turnbuckles. This product has been improved to be compatible with imperial-sized wrenches.

These kits are parts of the 2025 Everybot by Team 118. Designed to deep climb, this simple kit can help any team create a more competitive robot. 

AndyMark is happy to be working with Team 118 and their incredible Everybot team to make this climber available to all teams. The Everybot is an affordable, competitive, and elegant robot that can be created from accessible materials and tools. We are honored to be working directly on the Everybot project as we have admired the ambition and the team behind it since its beginning.

The Everybot robot was designed with the parts from the FIRST Kit of Parts, AM14U6 Chassis, and a few other tidbits included in the Climber Assembly.

Note: This kit does not include any tube plugs, box extrusion, or hinges.
