AMG Tonearm Details

I thought you might find interesting the AMG arm's unique bearing. At the very top you can see two cylindrical vertical posts. The protrusions atop them fit into the top of the tonearm housing and are secured to it.

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.
