You have not gotten any responses, so I'll add my "not really what you asked for" answer. I have a second gen T2800 Tacx Neo (2018 version of the original) which has about 200 hours on it, and it has required no maintenance.
How well used is the trainer? My understanding is the bearing issue is uncommon, so if it's been used for a while and doesn't have the issue, it seems like you should be confident that it will be ok.
