3500lb axles bad design
Probably most medium size trailers have the 3500lb axles and 10" brakes. The design of the spindles has little to no shoulder to locate the inner bearing. When I looked up the blueprints, I found th...

Here is a photo of an actual bearing, it measures 1.651" where it contacts the shoulder.
So, what's your point, and explain why no one else is having this problem.
Oh, and what did you base your claim about the contact being "about .020" and can be as little as zero using the print tolerances." What has a tolerance of .020, or even .010?
My point is that folks like you never recognized the issue and go about their merry way not knowing or caring about things mechanical. As long as the telephone poles keep coming at them, they never had a problem. I show actual photos and describe what I see and, for some reason, I am the villain. But I knew before posting that the finger pointers would come out in force.
You neglected to take into account the radius on the spindle shoulder. You also didn't understand that I said it was one of the better samples that I measured.
Now the real question is why would anyone take such things personally and come to the defense of such a marginal design.
