Printable Linear Bearing For 8mm Rods
by TheRooster
Description
Printed in ABS with 0.2mm layers height.
W/T : 2.5
The balls are 1/8" (3.175mm) steel balls I salvaged from old bikes when I was a kid, we can source them in bike parts stores. A complete bearing uses 88 balls.
The different pieces are drawn in google sketchup but the boolean operations are made with blender after a conversion to .stl
The "springs" put some pressure on the bearing and compensate an eventual wear.
The spikes in the spring fit inside small holes printed on the bearing.
It's a part of my current project, a self replicable 3D printer/mill/PCB engraver, each axis will be equipped with 4 of these bearings.
[edit]
Design update with captive M4 nuts
[edit]
2nd Design update : track improvement (larger on the outside) must be printed with 0.2mm layer height and W/T=2 because of the thiner outside wall

Excellent! Now I can finally put those rattling ebay LM8UU's (being the cheap sod I apparently am) to good use.

Very nice. Before long, I'm sure we'll see this design incorporated directly into the X axis sled of a RepRap. :-D
