What do we know about what happens if you remove the seal?
With product H we have a use the OEM part but remove the seal process. Done in the UK and done for several years. Unknown quantity and unknown miles and unknown analysis of long used bearings. UK forums not full of failure reports.
With product N we have a ceramic part and remove the seal. Lots out there and comparatively lots of years and miles. The forums aren't full of failure reports so we know at least something. Not the ultimate shape of the failure curves but something out to 50k.
With product C we have something similar to the N but small quantities.
And then there are two pressurized oil lubed bearings that are both different in their lubrication method but how many have been used and under what conditions? We have no data. Not even the sketchiest.
Since someone are doing an IMS to reduce risk, how much added risk is there to using one of the lesser known-about products even if their logic appeals to you?
Isn't the one common thing about the two approaches that have been in the wild for the longest that they use the "remove the seal" approach? Doesn't that tell us something about them getting enough lubrication? Maybe not enough to last forever but for a long time?
