Two companies using Si3N4 (Silicon Nitride) ball bearings in their arms are Audiomods and Helius Designs, both UK firms. Helius designer/maker Geoffrey Owen is familiar with Si3NR balls bearings, as they are used in the telescopes installed in the Space Shuttle, a project he was involved in (his other job is that of a rocker scientist ;-).
Rega tonearms using plastic bearings
Just came across this on Igus website as I use some igus bearings in linear applications at work.....

I have a Rega P-5 with RB700 that I rarely use as I prefer my Thorens 125 mk II & 160 considerably more.
I just thought this was interesting info on new bearings. If this is old news I apologize as it’s new to me.
thanks,
Johnny
