- Q: I'm buying a new skateboard with complete trucks, wheels and abec 3 bearings.I just wanted to know if it is any difference to Abec 5, 7, 9 ??
- Lucky Abec 3 Bearings Review
- Q: ok so i got a long board this Christmas and well....can i use 70% rubbing alcohol to clean them before i re lube them?and if i can then do i have to let them sit/shake them up a little longer to get them clean?and what kind of lubrication should i get to re lube them?and how long do you think my bearings, trucks , wheels and deck will last if i dont carve ( cause im only going to cruse ) only use my board when its sunny and dry out side and clean/ re lube my bearings every month?p.s. im 125 pounds if that makes a difference...MY LONG BOARD...arbor bamboo pintail72mm/78A arbor wheelsblack gullwing trucksabec 5 bearings (closed bearings )
- to clean skate bearings get accetone (preferable %90 or more) and remove the sheilds from your bearing. next place the acetone in a cup. next place you bearings in a cup. stir or shake until the dirt is out. dry . reasemble
- Q: i have a 1994 toyota pick-up with the 3.0 engine 4wd. the main bearings went out and i called to see how much they would cost and the guy asked me what kind they were. and i had no idea. anyideas?
- If the crank has been previously turned, undersize bearings often has a designation on the back side of the shell, 20 being .020 undersize. If the bearings are in really bad shape, the crank may have been damaged and you'll either need to get it turned or see about getting one already reconditioned from an auto parts store. And like chris said, usually standard and undersize are all the same price. When you were asked what kind, were you clear that you needed main bearings or was he asking if you were talking about main or rod bearings?
- Q: My car has no oil pressure and they said I need a pump and main and rod bearings. Can I just replace the pump? Or can you tell the bearings are shot by just hearing it?
- It will probably cost more to repair the T-bird than it is worth. I own a 2001, Jeep Grand Cherokee Laredo and recently had both transmission bearings replaced. It cost me $886; had a CO2 sensor replaced and it cost me $330. Auto repairs are extremely expensive. I agree with the first answer.
- 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: can i make my own ball bearings for hubs, bottom bracket, etc. from a ceramic mug or the like? if its possible, what tools do i need? can i get it done at a machine shop? i would only do this if its cheaper than buying them pre-made, which in case you didnt know, can cost several hundred dollars for a full set.
- oh man I hope you're kidding. for the time and effort you spend trying to get a complete functional set of ceramic bearings (which aren't the same stuff as a coffee mug anyway) you could get a second job at McD's and afford 3 real sets.
- Q: How to clean your skateboard bearings ????
- take it to the mechanic or you'll loosen up the housing
- Q: and are fast as hell bearingsgood?
- The quality and condition of the surfaces in which the bearings ride is equally as important. This is where you'll find a lot of the cost of expensive hubs and bottom brackets. A good A grade stainless ball is fine used with machined, ground, and polished races and a very minimum of lubricant... just enough to cover the races and bearings. Putting high end bearings into average races will bring you no benefits other than bragging rights.
- Q: i dont understand much about cars so can u explain it so i can understand
- the bearings are the attachment points for spinning parts. they allow virtually frictionless rotation with oil lubrication. think of a hand held pinwheel. the propellor is turning on a shaft. this is an example of a bearing on a shaft.
- Q: i heard people said it makes it stronger. but i dont know if they meant only to put the wheels inside to make the wheels stronger. because i dont want to break my bearings.thankz.
- Well i find putting any skate part in the freezer doesnt work i shred thro wheels in like 2 months. But if you want to try dont put bearings in the freezer also. Goooooood wheels - ricta's last forever and if you want to make your bearing work well i even use cleaner for bike chains in my bearings that works amazingly well
