WCP Tube Roller and Plugs

This innovative and versatile roller assembly is sure to revolutionize the intakes and game-piece conveyors of FRC. Our system allows any team to integrate a functional roller of any size into their design seamlessly and effortlessly. Simply cut a roller tube to the length you’d like, insert a plug on either end, bolt the plug in, attach to the gussets and bearings, and you’re on your way! There are three types of plugs: The plain tapped hole, the hex bore, and the plain tapped hole with added hex shaft. Check out the examples that show how to use each one!

1.625 Flex Wheel

Ideal for grabbing rigid game objects, these compact, compressible rollers slide onto a hex shaft and are easily stackable. 4” diameter version and hubs coming soon!

Polycord Pulleys

These plastic pulleys make polycord simple and easy to use. Just slide onto a hex shaft, wrap your polycord around and connect it, and you’re good to go! Available in single and double cord widths!

¼” Polycord

Polycord belting has been around in FRC for ages as an effective manner of conveying game objects within a robot. Couple this with the WCP Polycord Pulleys and you can have a lightweight and reliable power transmittance to transport your game pieces to where they need to be.
