DM uses Igus rod end bearings, but I haven’t had the chance to play with magnetic ball joints. We’ve had varying issues with them. The tolerances across a whole bunch of parts at one point meant we were popping out the balls with an arbor press, and then re-seating them in order to get them to loosen up. KARM type.

Cool, what do the igus parts cost?
