The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. ... Because the balls are rolling they have a much lower coefficient of friction than if two flat surfaces were sliding against each other. ahahaha i just copied this from the internet :)

Why has my 2005 Maxima had 3 wheel bearings go out in less than 65000 miles?

aftermarket wheels with incorrect offset, loose axle, driving on sand with bad bearing seals... There are probably many reasons such a thing can happen; I had a similar problem with my 1997 Nissan Maxima GLE: the front bearings (both sides) replaced three times within a year. The mechanics did not seem to know or even care why, but any one with a brain could figure something wasn't right. I changed mechanic. Thank God I found a mechanic that knew his stuff. He told me that my car needed to have new hubs installed with new bearings, because even if the bearings were seated properly on the old hubs they would wear down in short order. This, he said, was due to the the old hubs having wear. He was right. New hubs with new bearings solved my problem. Trust this information may help you.

How do you change hubs on a bmx bike?

There's usually not much point in changing hubs, as that requires tearing the wheels completely apart - spoke by spoke. and unless the flanges of the new hubs are within mm of the same size the old spokes won't fit. Often cheaper simply to buy new wheels. But if you insist: remove every spoke from the hub + rim , then lace up the new hubs to the old rim, tension and true.

How to Replace wheel bearings on Pathfinder suitcase?

Not sure about Pathfinder in general, but a lot of suitcases use standard 60-70mm inline skate wheels nowadays, which all have the same, removable ball-bearings (2 per wheel). I recently got a suitcase that was missing one of the ball bearings on one wheel. I replaced it by popping-out one of the bearings from an old pair of inline skates and putting this into the malfunctioning wheel. The bearings in the case had ~5mm standoff hubs, which I approximated by adding a couple of washers to the outside of the wheel. Removing bearings is a little fiddly - I just wedged a small flathead screwdriver against the inside edge of one bearing (i.e. insert screwdriver from the opposite side of the bearing you're removing). Then braced the driver handle against a table and pushed down on the wheel to easily pop-out the bearing. It now works fairly well (Certainly better than when it arrived).

Does a Ford F250 4X4 have locking hubs or is it shift on the fly?

I have a 2005 which does have locking hubs, but that is so you can lock your differential from slipping. If you're stuck on a hill with all 4 wheels spinning, lock the hubs and your gear ratio is far apart, your front wheels won't spin, and the front wheels will actually do the pulling. Whether yours has locking hubs depends on the year of F250. Later F250's, I believe beginning with the 1998 models, do have auto-locking / manual hubs. The later F250 hubs can be activated manually or electronically. When you electronically turn on the 4wd ("shift-on-the-fly"), you engage the transfer case, front drive shaft, and front axle shafts. Also, when you electronically turn on the 4wd you activate a vacuum solenoid, which provides a vacuum source to each of your front hubs to engage them. The front hubs only connect the front wheels to the front axle shafts and has nothing to do with the front axle differential, which is an open differential unless you have a differential other than the factory installed piece.
