You'd have to know HOW the bearings are arranged and mounted in the "driven" bits. It could be non-trivial. If the driven shaft is set up with TWO tapered roller bearings, one on each end, opposing each other (which I was taught in Mechanical Engineering school many years ago is the best way to use tapered roller bearings), you need do NOTHING, and apparently the Polini is set up this way, but NOT the Vitorazzi. IF the predominant thrust you're trying to resist is from ONE direction, you can economize and use a roller taper thrust bearing on one end, and a ball bearing on the other. There are lots of other ways to do it, with radial needle bearings, sliding shoe bearings, boundary lubricated plain bearings, etc.Would there be much rocket science in modifying a paramotor for a tractor prop? Could it be as simple as flipping a couple tapered bearings around?
