Rega tonearms using plastic bearings

I was just surprised that work and hobby intersected.
I am a Maintenance Tech for a welding fabrication manufacturer in the O & G market.
Not often do my suppliers have anything to do with audio. Although I once got a screaming deal on 2 Jelco tonearms from a salesman;)
thanks for the replies

Plastic?  Sounds ludicrous but here's an interesting article from 2017 that confirms it:

POM and its variants make strong and long-lasting bearings.

Nothing surprises me any more.

There are some seriously tough plastics out there that are self lubricating and make excellent bearings. People may not realize this but simple, plain bearings like you find in an automotive crank shafts are far more durable than ball bearings. You would not use plastic in an engine due to the heat but in a tonearm no problem.
