💡 What makes ball transfer units handy for moving heavy loads on custom machines?
This setup uses a spinning nylon orb on a fixed rod, which keeps your rig tracking straight while taking the heat off the drive motors. The natural pivot action stops grinding when you change direction fast.
* Cuts motor load by letting weights glide instead of scraping against plates
* Absorbs side bumps on garage workbenches so your builds stay level
* Keeps things centered on linear tracks when pushing heavy components around
* Changes out fast with a standard wrench since threads grab right into tapped bosses
