Summary

This linear bearing has four tubes that are filled with a number of bbs. The bearing has a cap that is held on with two screws.

I have now included the 6mm and 8mm versions of the bearing

External mounting is performed with zip ties passed around the decorative ribs on the bearing.

I designed this as a replacement for the Lm8uu 8mm linear bearing.

These bearings are louder than a standard bearing. It is important to note that using steel with copper is not the best solution. Steel shot are a better solution, but not as easy as bbs to get ahold of. besides........

These bearings only cost 35 cents to make. Including the copper bbs.

Instructions

Bring Your Own BBs

1/4" Circulator version added.

6mm which uses 1.77mm copper bbs or steel shot
8mm which uses 1.77mm copper bbs or steel shot
1/4" which uses 1.77mm copper bbs or steel shot

You can use either 1.77 mm bbs or find some 1.77 steel shot and make your own bearing. The bulk of the bearing is due to 3d printer limitations concerning walls.

I suggest printing at .2 layer height.

For ABS plastic, I suggest that you glue the bearing together with some Acetpaste. (Acetone and melted abs).

I prefer PLA for this bearing, as the strength adds to the life of the part.

P.S. Out of everything I've built, I really think that this part is the most useful.

Dude You cannot use Any of them why did you not fix the Bearing?
this is a REALLY good Idea if you make the STL file Work I would have to Use Rino8 and Repair it before I could even Use it.

I have tried to repair the STL file for this and am not having any luck. the object is not manifold. Do you think you could fix this?

For some reason I can not slice this and I would really like to try out the design. Everytime I slice it tells me that the part is not manifold. When I try to open this in Solidworks I can not correct it as I have been able to do with some other files. Suggestions?

Thanks for the 1/4" version. I am just getting started a parametric version in OpenSCAD. I did some searching first. And it seems that a few other people have posted projects for linear bearings. I found one in OpenSCAD (http://www.thingiverse.com/thing:6159)http://www.thingiverse.com/thi.... There are several other projects all with good ideas and varying experiences. I'll try to learn all I can from everything and then see if there is anything I can add to all of this work.

Linear Bearing for Airsoft BBs

hey u should standarize ball infill and make it parametric to choose what inner diameter one choose and it could be nice add on to replace prusa vitamin :D gr8 design

Thats not a bad idea, any of them. I havent figured out a parametric program yet. I'm still using training wheels. (sketchup)

Tell me what rod sizes you want and I'll maike it.

I agree that it could be very useful. I would like to print this for 1/4" and 6 mm rod sizes. Is it possible to post the design files so I could resize them? OpenSCAD, if you have it.

MM,

I uploaded the sketchup file I used. I havent gotten into a parametric design program yet. I am lookign at Alibre.

Thank you for the sketchup file. I'll see if I can parameterize it in OpenSCAD. I'll post it as a derivative when it is ready. This may take me a while. So, in the meantime, could you also post a 1/4" rod version.

the 1/4 inch part is up

I'll get that up later today.
