A few anecdotes.
1) In USA, at one time cars delivered by rail, (on Auto Racks) were found to have damaged wheel bearings, "Brinelling", caused by the vibration of running over the track. Setting the vehicles on their tyres, instead of standing them more or less up on end, solved the problem. The rubber tyres decoupled the bearings from the vibration; being, literally rubber mountings.
2) A particular Lanchester balancer, in an engine used to Brinell the shafts. It was found that: the key way for the driving gears threw the shaft slightly out of balance, and that the ratio of needle roller diameter to shaft diameter was an almost exact integer. This combination meant that a needle was regularly hammered against the same area of the shaft, leading to the damage. Dimensional changes, solved that problem.
3) I once wrecked a set of taper roller wheel bearings by failing to adjust for endfloat.
4) The feel of the steering and self centering were improved on one make of car, by adjusting the taper roller bearings in the front wheels to provide 0.002" – 0.004" endfloat.
5) Disliking pounding bearings, I made up an extractor that could be screwed to the drive pulley, and used to thrust on the slackened drawbar, to "break" the 3MT taper in my Mill/Drill. After over 15 years, the bearings still seem to be in good condition. A long time ago, I had to replace the 3/8 BSW thread on the lower end of the drawbar!
I know that taper roller bearings in machine tools are deliberately adjusted to give a preload, but the bearings are selected, by design, and are presumably "oversized" to live in these conditions.
