Semi – levitated magnetic bearing

I am working with bearing friction on my long running projects. One way to reduce the friction is to take the weight off the bearing surface. Here I look at a semi – levitation permanent magnet method acting on a single point contact bearing surface.
Dirt getting into the bearing is another cause of increased friction. Putting the bearing surface under cover is an easy solution.
The materials used on the bearing and the type of lubrication are also very imporant on the small low power motors I build.
