Q: I have alot of wheels from the 1980's cuz i only ride the stuff from then. Well i have some of my wheels that the bearings will spread apart in once i have the wheel onto the truck. I would have the wheel to where it would wiggle on the truck so that way the wheel would spin nicely. But i have noticed that once i do some kickturns and what not, the wheel would start slowing way down and the cause of this would be with the bearings spreading even if i have spacers in each wheel. Some of my powell peralta wheels dont do it but a few of my other brand name ones do. Is there anyone that could give me some hints or ideas on how to fix this problem.: you need to put the bearings in or grease, stick the bearings in the wheels then make sure the skateboard can move well but if it doesn't work just buy some new ones that are already made.

Q: You have nine ball-bearings, all of the same size but one slightly heavier than the others, though not enough to be detected by holding them. You have some balance scales and are allowed to do only two weighing of any number of ball bearings. How do you find the heavy one?P.S. please answer this so I could get 5 extra points in my exam .lol thanks!!!: Weigh three ball bearings against another three ball bearings. If one side goes down then you know the heavy one is one of those three. If the scale balances then it is one of the ones you didn't weigh. Weight two of the three containing the heavy ball against each other. If one side goes down then it is the heavy one. If the scales balance then the heavy one is the one you didn't weigh.

Q: can you use these bearing interchangable?: N design Inside track with two unitary flanges, while outside track without flange. Axes's axial displacement to bearing block can be endured by bearing from two directions. Therefore, these bearings usually used as non position end bearings. NU design The outside track of NU design bearings has two unitary flanges, while inside track without flange. Axis's axial displacement to bearing block can be duded by bearing from two directions. Therefore, these bearings usually used as non position end bearings. Due to the reason of manufacture and maintenance, two flanges of outside track of NU design big bearings showed on drawing maybe not unitary, but with loose fit-up flange rings. NJ design Outside track has two unitary flanges, inside track also with one unitary flange. Therefore, these bearings suitable for the axial orientation of axes from one direction. Since their design and usage are for different purposes I would say no they are not interchangeable.

Q: They are the Mission Abec 9's: There really isn't that much difference between bearings. Mission won't want to get a bad rep by making bad bearings for their main customers. The price is probably a little higher than other bearings (without an OEM skate maker's name on them) than equivalent bearings from the top companies (Twin Cam, Zero Drag, Bones).

Q: Well, I was wondering: do all skateboard bearings have 2 sides? I looked at abec 7 or 8 bearings and they do not seem to have 2 sides? How do I know which side should i grease? Also, does abec bearings have a metal/rubber covering on one side? Thanks, if you can answer all these questions, i will give you best answer. Don't say, Get bone swiss bearings! They're better! I know they are, but I'm asking about abec 7 bearings. Thanks.: By sides, I assume that you mean the shields that are there to block dirt from getting in. Only one shield is needed. Some makers include both and some only one. (This applies to ABEC 7 or any other bearing) The one on the wheel side is not needed since no dirt can get in there except through the other side. You don't grease the shields. There is only one set of balls in the bearing and greasing from either side will do the same thing. ABEC ratings are meaningless for skate boards or inline skates. The ratings are for vibration and accuracy in high speed industrial machines. You can get ABEC 7 bearings that are garbage or non-rated (Bones, TwinCam, and ZeroDrag all make non-ABEC bearings as their top models) bearings that are extremely good.

Q: 90 15ierra 4cyl 4 tech motor.oil pump came loose and rod bearins turned and have the motor up nd pn off. m just curous if theres an easy way to take them out?do i takeone out the turn the motor to get to th other bearings?: are you sure only the rod bearings are affected and no damage to crank pin ? remove the oil pan and work under the engine. when you remove the oil pan you can have access to connecting rods, you just unbolt the rod cap and replace the bearings then re-torque back the cap's bolts. you may turn the crankshaft while working around on each rod..

Q: are these above, just consumable type things ,that need replacing after time, how many miles for each generally speaking would they need to get replacedwhat are signs that track rod ends have excessive playwhat are signs that wheel bearings have excessive play, and what exactly do they do: if they bad now the best time to do it since tie rod control s steering breaks you crash wheel bearing control wheel spin breaks wheel locks up or comes off you crash wheel cylinders part of brake system no brakes you crash driving any amount of tiem with any of them bad not smart crashing cost you way more than parts will your car your life few hundred buck notr hard for me to know which id pick fix the car over my life any day of week

Q: What are the needle roller bearings with an inner diameter of 14, an outer diameter of 20 and a width of 20?: I didn't find a modelIt should be non-standard

Q: Also on bicycle is it possible to adjust the cone too tight to a extent that it costs me wattage?On bicycle is there any kind of mechanism that prevents the cone from getting too close to the bearings, so I can just tighten the cone as much as I want without worrying about restricting the bearing movements?On bicycle will the cone loosen up over time and need re-tightening?On bicycle will I be paranoid about either the cone being too close to the bearings causing drag or too far causing plays?Finally are cup and cone hubs good for cycle commute or will you recommend cartridge which is maintenance free?: Not so long ago, racers- particularly velodrome racers- built their hubs using very light machine oil instead of grease and ran the bearings slightly loose. This was called trackmens slack inasmush as using the hubs like this offered almost no resistance. Unfortunately, one race like this and the hubs required rebuilding including replacement of balls, cups, and cones. Whenever I can, I still spec cup and cone hubs on bikes I design and build most of my own bikes with cup and cone hubs. EDIT: I wanted to add that ball, radial, and needle bearings which are used for just about everything now in some fashion were first developed for the bicycle. Before the bicycle, bearings were made of wood, leather, and bronze. The bronze ones were called babbett bearings.. similar to sleeve bearings today... but not exactly.

Q: how do u clean skateboard bearings?: you take s socket wrench and loosen the nut and take it off and take off the washer , than the wheel than the other washer . Don't lose ur washers !!! Do this to each wheel . Take about 8 Qtips or more or less depending on how dirty ur bearings are , take the Q tip and rub the dirt off of the bearing . Each side and in the insides .
