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: I have inline skates manufactured by K2, I need new wheels, and maybe bearings, I noticed that non-brand names are cheaper, are most common types of inline skate wheels and bearings interchangeable?: Yes, okorder . For 80-84mm wheels, the zero drag wheels are really fast rolling. He sells kits with wheels and bearings (you still need your bearing spacers or can buy new ones from him). If you have questions, send him an email. I know Bob personally. He is an avid skater (other than that his business taking up time when he could be skating) and is knowledgeable about his products from both a skating and his engineering background.

Q: are Tensor Oust Moc 7 Bearings, Abec 9 Tolerance good skateboarding bearings?: well i say anything above abec five is pointless (unless its bones bearing, well because they are the best) but i would go with abec 7s. theylle will get worn out faster so i would just buy bones red because they last and are cheap.

Q: Okay so I'm buying 2 80mm/78a rink rat wheels and 2 72mm/78a wheels. But I need to buy some new good bearings that can go fast but arent to expensive. Please leave me a link or tell me what to type in the search bar to find them thanks.: check okorder /

Q: does a 1991 mazda 626 have front wheel bearings?: Of course it does. ALL wheels have bearings, no matter what make or model of vehicle you have. Even wheelbarrows need bearings in the wheel. The possible exceptions are the single ball type wheels that have a hollow sleeve in the centre as opposed to a roller or pin type bearing as is the norm. Hope this helps.

Q: okay...lemme explain...i have an experiment in my criminalistics class on improvised weaponry and I figured, hey, stupid...(that's me) this sounds like a great(dangerous and stupid,with potential for serious bodily harm) idea. Gee, wonder what would happen if I do it?(most likely,PAIN.)how much damag would this cause to a human body? car? building, such as a wood shed(mine)....can this be done? will it destroy my(roommates, cause I sure as hell wont do it to mine!) gun? anyone know how quickly the ball bearings would come out? damage they'd inflict/ etc?any help would be enormously appreciated!: Metal Ball Bearing Gun

Q: gt;????: ?!?!?! NO! Finger acetone cannot be used to clean bearings. You can clean bearings with a few things, I can only remember WD-40 at this point of time. Remember to completely dry the bearings before adding the correct lubricant and re-capping them.

Q: Cylindrical roller bearings and needle roller bearings is the same thing?: It's certainly not the same thing. Look at the mechanical manual. Top of it. See what you've got

Q: how can loose fits cause failure in bearings? and in particular affect the outer diameter?i am seeing a failure catalog for bearings, and i read : discolartion and scoring is the result of the outer ring slipping in the housing. why outer ring?: Bearings are matched to shafts and housings to a tolerance of .01mm (ideally). This fit permits creep to distribute wear over time, while providing uniform and stable support for the inner and outer races. Tighter (interference) fits are destructive. Loose fits, which permit chatter and impact, are equally destructive. If you are involved in maintenance you will get your money's worth from the attached link.
