1/4 Inch Circulation Bearing
thingiverse
This is my best bearing to date. This 1/4 inch bearing has 4 channels that the maker fills with BBs. PVCing the cap on takes a few seconds, and you now have a bearing that only takes steel shot or BBs and plastic. Lets create more parts on our own! Forget store-bought linear bearings! (Created in Cubify Invent) Instructions Fill with BBs or steel shot, PVC the cap in place and Voila! I know its a big file, but I have stopped using Sketchup and am now able to create more complex designs.
