Q:Can you use bearings from skateboards for inline hockey skates?
Good point Brandon... and nice purple mohawk! You definitely will need more bearings.
Q:How do you change rear bearings on a 94 thunderbird?
rear bearings in the engine or the differential. the two are very different but either one would be a project. the engine, you would have to pull the engine out or pull the oil pan off and deal with it that way. pull all of the main bearing caps and replace them. the rear end is a bit more complex as you have to pull the axles out, pull the carrier and start from there.
Q:What kind of bearings in a haro bmx bike?
Does the bike still have it's original HARO splined bottom bracket axle? If so, it will have loose bearings in a race that run in the outer cups at each end of the axle. There's not much you can change about those other than maybe some heavier duty ones if you're hard on the bike. Best bottom brackets have sealed bearings and tend to run smoother for longer. Not sure what type the HARO has, as they were originally made in the US, I'd guess they have an American BB. Euro's are best in my opinion. If you need to alter the internal diameter of the BB shell, you can buy adaptor kits.
Q:i need to know how to measure ball bearings? The bore size is simply five times the third and fourth digits together. 0 through 3, however, are different: 00 10mm 01 12mm 02 15mm 03 17mm See links below. Good luck with your engine! Bill
Q:What are good set of wheels, bearings and spacers for outdoor rollerblading?
If they should b able to help you
Q:how are these skateboard bearings?
Q:How fast are the Abec 3 bearings for skateboards?
ABEC ratings have nothing to do with speed or anything else to do with skateboards or skates. Actually, the higher ratings could be slower. The ABEC rating is for smaller gaps between the parts so that they do not vibrate in high speed machines. You won't be into the range that the specs relate to until you are over 200 mph. Some of the top makers of skate bearings (Zero Drag, Twin Cam, Bones) have designed their best bearings to have larger gaps in critical areas to roll faster but the gaps mean that they don't even meet the ABEC 1 standard. The lubricant used in a bearing will have more effect on it's speed than anything else. Light oil is fast but you need to add it more often. Grease will last for years but is sluggish if more than a tiny amount is used. Gels are in between. Unless you have extremely different bearings (like oil vs over greased), your wheels will have a much larger effect on your speed than the bearings.
Q:bearings on 2001 jetta?
NO! We don't know what bearings you are talking about. There are many rotating parts in a car. Don't you think they would all have bearings? Wheel bearings, axle bearings, cam bearings, crank bearings, water pump bearings, alternator bearings, power steering pump bearings.......What ones would you like to know about?
Q:Could this have caused my alternator bearings to fail?
Q:what is the typical repair cost for front wheel bearings in a 1990 toyota 4runner?
front wheel bearings? disc brakes? rotor replacement and new bearings (don't forget to pack the bearings w/ GREASE!) cost me almost 100 bux (for the parts)and a 12 pack for my buddy to do the work.. for both front wheel bearings/rotors..
