It has taken us a while to fix this bearing issue, but I do believe that we have this nailed.
As we found out last year, that inner race for the FR6ZZ-Hex bearing (the dreaded
am-0439) was too thin and can only handle light loads. This this revelation, we have been able to get a new bearing made. This time, the outside diameter is 1.125", which leaves plenty of room for a very thick inner race.
Thank you to everyone regarding this issue. Your patience and detailed information was very much appreciated.
So, without bearing any further load on this, I introduce to you our FR6ZZL-Hex bearing,
am-0692.
Sincerely,
Andy
