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.
