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
