Q:is there a difference between longboard bearings and regular bearings?
Not really. Regular skate- bearings take more of a beating so I tend not to buy overly expensive ones. A long board should definitely get some nice speed bearings. If you clean them regularly and keep them lubed they'll last you forever. DON'T USE WD40 TO LUBE THEM. For cleaning it's ok... because it helps protest them from rust and wear. You can actually buy a specific lube wherever you get the bearings.
Q:Working principle of one-way needle roller bearings
One way needle roller has a spring in the lower part of the needle
Q:is it possible to make your own ball bearings?
ball bearings are made from hardened steel, which is a process requiring ovens, and cool down systems, and precision is important, so I think it would cost you more to try to manufacture them yourself. I always go to a bearing company, Look in the yellow pages. they can cross reference ANY bearing and replace them cheap. For instance the ones on my boat were about $30 and they cross referenced them for about $4. Good luck.
Q:does all bearings fit on every skateboard or nah?
608 STANDARD The most common bearing size is the “608.” Characterized by an 8mm core, a 22mm outer diameter and a 7mm width, these bearings are the industry standard and match up with nearly every skate wheel out there. There are also mini-bearings that can be used with the standard 608 bearing hub, but they require a sleeve to make them compatible.
Q:what are the best skateboarding bearings ?

Q:How much would it cost to replace the rod bearings in a 1987 Pontiac Fiero?
the only thing about that is if the bearings are knocking then the crank might be scared. i believe i would stay clear of that car. something made those bearings go, maybe a bad oil pump.
Q:Is this price right to fix my wheel bearings on my car?
The hub has bearings in it. If the bearing started to go bad and you keep driving on it. That in turn will damage the axle shaft. You have to replaced the front hub which come with new bearings, axle, axle seal, ect. Parts can be had for about 300 on the net. But taking it somewhere for about 1200 sound about right. If your mechanically inclined you could fix it yourself. Spending 1200 bucks on that van does not make sense to me.
Q:i have a question about skateboarding bearings?
Good bearings don't have an ABEC rating, just get Bones Reds or if you have money get Bones Swiss. They go hella fast and are way better than most bearings. If you have to get an ABEC bearing get 7s
Q:How do you use ball bearings to support axial force?
There are pressure bearings which are installed (in your case) at the bottom of a vertical rotating shaft to support the weight or downward pressure of it and reduce friction. Those bearings are usually roller or needle bearings. I have seen them also with steel balls but having an identical top and bottom plate or ring. It is unwise to use regular ball bearings with an inner and outer ring for that.
Q:What are the differences between needle roller bearings and cylindrical roller bearings?
Mainly the difference between rolling bodiesThe needle length and diameter ratio (aspect ratio) is greater than 3, less than 5 mm in diameterThe cylindrical length and diameter ratio (aspect ratio) is less than 3, greater than 5 mm in diameter.
