Hi Aaron:

It is hard to diagnose bearing failure without the bearing in hand. Could 
you take a photo of a ruined one (dismantled) so we could see it? there are 
lots of failure modes, corrosion, flaking, etc. My Maxant 20 frame extractor 
has been working for 30 years with no bearing problems at all. The bottom 
bearing has a grease nipple and the bearing is raised up so that honey does 
not get into it.

                                    Best regards

                                    Donald Aitken
