You ever seen a freight train rolling in with a burning bearing unit. Pretty interesting.
I would think the bearing slot would expand (under any kind of heat) and shrink, due to expansion and the bearing race would follow suit and expand.
Under normal conditions with a correct diameter bearing slot it shouldn't walk out?
I think Stanton has proven this in his design, but also uses lock collars if I'm not mistaken.
reread, what I wrote. If it is under extreme heat, sure, but normal operation no. If that was the case, why are my roller bearings on my motorcycle working as intended? If they expanded out of bore, or the bore expanded out of spec during use, the engine would die. Hence, why there is an " interference " fit. A slide fit will bore itself out under normal operation. An interference fit will not. The reason it has been used for many hundreds of years. If it's worked for hundreds of years, I think they were on to something. If the bearing fails, 99% of the time, the race is still there and you can swap them out. Like on an axle bearing on a tuck. If the bearing walks, it was either under extreme stress and heat, way out of spec's range, or the machining was not done correctly. Usually when out of spec with extreme heat, it was the operator not inspecting their machine before use. Not a design flaw, an operator error. The failed to see the bad bearing and replace before complete failure.
edit: an on these bikes, always an operator error for allowing it to go so far bad, when bearing swap should have been done. Most of you guys don't inspect your rides before riding. You jump on and go like it is a factory built motorcycle( I even inspect my factory built motorcycle before riding, I'm liable, not the maker), again, operator error. I have had one wheel bearing failure during my years of these bikes, why you ask, I failed to inspect the bearings. All my fault. I know everyone loves to blame the maker, over their own mistake. Hard for people to admit when they are an idiot. The wheel bearing failure, I was an idiot. I never have done it again either. I check my rides before riding. The failure is on me, not the engine company. If it fails completely, it was because I failed to check itm not because the manufacture of the kit. Now when it first rides, still check, there can be flaws, but if caught before complete failure, repairs can be made before injury or machine destruction.
