AMG Tonearm Details
The very small diameter wires between the cylinders and the bearing body are the vertical bearings. There's no bearing "play" because there's no bearing in the traditional sense.
The horizontal bearing system is a more traditional but very long roller bearing. The adjustment being made is to a magnet that sets anti-skating.
Like the platter bearing, the designer has come up with a unique, yet very sensible solution to tonearm bearing design.
