Q: Air bearings have been used in large centrifuges and gyroscopes.: Yes they'd work, but not cost effective. Ball bearings already have very low friction. It's not worth the cost and compexity to go from maybe 2% friction to zero. You may even lose as it takes some energy to constantly pump up the bearings.

Q: trying to figure out what type of bearing could be used in a pulley system with dynamic loads exceeding 1150 lb and 540 lb.: Ball bearings manufacturers give detailed procedure on how to calculate and arrive to the proper selection. I advise to contact them and obtain their catalogues.

Q: i heard about bones but are there any others?: doesn't really matter but just ger bones reds, or flip HKD. the best is bones swiss ceramics fer like 100 bucks

Q: I'm getting some ABEC 5 bearings, but I don't know if I need them sealed or shielded. Right now I'm a beginner so I'm just cruising with the occasional hill if that makes a difference in what I need.: Some people mistakenly call shields as seals. No one actually uses seals on skates or boards, they create too much drag. If the drag wasn't there, they would be great since they would actually keep water out. It doesn't matter if you get bearings with metal shields or the neoprene coated ones (more likely to be mistakenly called seals. The neoprene ones are all removable for cleaning and lubricating. Most metal shields are removable but occasionally you find non serviceable bearings that have shields that are permanently staked in place. With some work, you can remove the shields on non serviceable bearings by destroying one of them. You only need one shield that is the side of the bearing you see from the outside.

Q: Road bike. Mostly used on roads but occasionally used on loose rock roads.: If the bearings can be serviced, about once per year. If they are sealed bearings, you replace them when they start to fail. You can also disassemble and service your hubs yearly. How this is done depends on the specific hubs you have

Q: i have a 2003 suzuki ozark 250, and the front wheel bearings are shot. I have the bearings, but before i start, i would like to have an idea of what im doing. Is it anything like replacing wheel bearings on a car? If so, just say its like that and i should be good to go. i've looked all over the internet for instructions, but i cannot find any. Ive changed car wheel bearings before, so if its anything like that, then say so. If not, post a link or description on how to do it. thanks: is almost the same, the only diff is how the wheel is opened up,,, i believe they seal the bearings so you will haft to press them out i think,, if not then then its the same,,, ive only came across 2 types of 4wheelers that had to do that,, they were polarius models that floated on the water,,, now lookin at yours its the same as a car,,, after removing the wheel you take off the spindle ( for a car its called a rotor) then pick out the bearing clean out the grease add new grease, and pack the bearings with grease befor you put it in,, the more grease the better lol

Q: and are fast as hell bearingsgood?: The best bearing is a new bearing. I have found also that any and all sizes of sealed bearings can be purchased at an electric motor supply store for a very reduced price.

Q: examples.: Axle wheels on PWC trailer.

Q: Why do so many large railroads (ie,class I) flat out refuse to let rolling stock that has friction bearings, from operating or (at the very least) being moved across their system(s), even if the equipment is maintained in a better condition than roller bearing items of the same type/vintage?I appreciate all insight, -- Thanks in advance!: Friction bearings are not illegal, but banned for interchange per AAR interchange rules. So the car owner can't force the railroad to take the car. Railroads could accept the car at their discretion, but lately the class I's have been very risk-averse. Probably because their railroads are darn busy. I have heard of a few interesting hospital moves of large blocks of heritage equipment including Shays on their own wheels. However this was done by someone very influential with the Class I involved, and at the least busy times (i.e. Christmas day).

Q: I heard using mineral spirits is a good way to clean bearings, but I also heard some can end up damaging them: WD40! Get a can and a small dish / bowl... Fill the bowl up 3/4 complete with this WD40 and enable the bearing soak in it over night. the subsequent morning you may pull them out and wipe them down... ultimately merely grease the bearings and positioned them lower back in.
