8mm REX™ Shaft Starter Pack

Whether you’re dipping your toes into the waters of project-building, or stocking up your toolbox to add to your record of innovations, the 8mm REX™ Shaft Starter Pack is a fantastic way to get up-and-running with shaft-driven motion and make sure that your next build has exactly the motion foundation it needs!

• This R&D-curated Pack includes:
  A special selection of the most popular lengths of stainless steel 2106 Series 8mm REX™ shafting, which features an e-clip for easy component constraint
• Four Sonic Hubs and four Hyper Hubs, all 8mm REX™ bore and featuring the goBILDA® 16mm hole pattern—which you can utilize via included M4 hardware (screws and washers) to attach and drive motion components throughout the build system
• Sixteen 8mm REX™ bore bearings for smooth rotation in the goBILDA® 14mm center hole pattern
• One 8mm REX™ bore Hyper Coupler for ensuring super-secure rotational transfer and connectivity from one 8mm REX™ shaft to another
• Two 8mm REX™ bore collars, twelve 8mm ID stainless steel shims, and sixteen 8mm ID spacers (across four different lengths of spacer) to provide exactly the component spacing and constraint that you need

8mm REX™ shafting is the signature motion component of the goBILDA® build system. It combines an 8mm Round profile with a 7mm hEX to provide the best of both worlds: you can use it with 8mm round bore bearings and spacers, while simultaneously achieving positive drive with 8mm REX™ bore motion components throughout the build system—such as hubs (like those included in this Pack), as well as gears, wheels, sprockets, and pulleys (purchasable separately).
