Optimization:
Use metallic spheres, it is cheap and easy to find, just adjust the parameters to match.
The bearing uploaded use spheres of 2mm, is 25mm in height, 20mm in diameter and is for use with 8mm diameter shaft.

Attention:
The value for "bearing internal diameter" is not the bearing hole, it is the shaft diameter.
The number of spheres is the quantity of channels for the spheres.
The number of spheres in the line is calculated with base in the bearing height.
