Hello, nobody knows who made the bearing.
I'd like to state again, I'm 100% sure that there is no deflection, and even if there was, the way the bearing is constructed, some misalignment or deflection will not have any impact on the operation of the bearing. I would say that the rudder shaft could bend up to 10 degrees of arc
before bearing performance was compromised.
Carbon fiber does not bend like that. It would fail long before it reached anywhere near the deflection needed to compromise bearing function.
I wish I had a picture, then we wouldn't have to keep having the 'deflection/misalignment' conversation. The rudders are massively overbuilt carbon structures, designed to survive a heavy impact due to their location on the boat. These things simply are not down there flexing. The bearings are fairly new in their installations, as well. Wear is not a factor.
Also, note that 1/2 of this equation is stainless steel
. The other half is carbon fiber. Does that make it a non-metallic bearing? I don't know.
I'm really, really, absolutely, positively sure that this is simply an issue of the stainless inner race
pressing hard enough on the carbon outer race
that it is creating friction during the heaviest part of the load cycle in a very limited set of sailing conditions. Hence the plan to replace these with roller bearings at the next haul. In the meantime, I wish to lubricate them with something to help out with this small issue.
So, I guess that my question is, considering the materials involved, am I actually going to destroy carbon fiber with any type of lubricant?
Thanks, I don't mean to be snippy, but this same thing keeps coming up, and it's just not happening that way.
Insight into lubricants destroying carbon would be appreciated, however.
