they are rather basic. abec is a well known brand for mediocre but usable berings.
the rating system is a way of categorizing the quality of their barings out of the manufacturing plant and the quality of the grease used in them.
the scale is 3,5,7,9,11
but 3,5,7 are the most common and 5 is the middle of the road for that. i ride abec 9's and I could never get anything lower because I would feel slow
Carbon, hydrogen, oxygen, nitrogen, and sulfur. The same as in your own proteins - except for the excess of carbon.
the 5 types of fossils are: 1.petrified fossil 2.carbon films 3.trace fossil 4.perserved remains 5.mold and cast
Plants need the following to make food 1-Water 2-Light 3-Soil 4-Carbon dioxide 5-Nutrients
5 examples of gases found in the normal home environment include; oxygen (air), nitrogen (most abundant element found in the air), carbon dioxide (air and the bubbles in fizzy drinks), argon in air and finally, methane if there is a gas supply, or propane or butane in fuel gas bottles. Carbon monoxide and SO2. are present in polluted air. You might have helium in a balloon.
acid rain, wind, tidal, water on surface & chemical
On the ABEC scale 7 is better but 5 is not the lowest. The scale numbers are 1, 3, 5, 7, and 9, so a five would still be a good choice.
abec 5 or 7
I have reds bones on my almost setup and they are abec 5's
Yes: the amount of revolutions matters depending on how much friction is present in the bearings between the trucks. Abec 5, Abec 7, and Bones Swiss are all good for speed
I have a Christine Skateboard and it works ok. I changed the bearings to abec 5 and to 54mm wheels it works just fine
Well I Usually skate abec 5 for fliptricks flatgroud and grinds but a 7-swiss ceramics on my vert setup and for stairs and gaps
I've never had a good set of abec 3's. They are fast for about a day and they're shot. I would highly recommend blowing the money on some Bones Swiss. They last around 5 times longer than the best abec 3's. Just stay away from water, mud, thick dirt, or anything that may gunk up your bearings.
Some people may not think that Abec 13 bearings are real but they really are, you probably don't know 'cause they have only recently been brought out. And for the people that don't know this, all Abec bearings are ranked with numbers so 1 is worst 2 is better than 1 and so on. Another fact is that the only Abec waterproof bearings are 7 or 5 I'm not that sure!
I just got myself some of those n they're not bad, quite fast im thinkn they'd be around abec 5? N they look slick
I don't doubt the quality of bones but as for abec9, abec7 etc, most of them are not abec9, abec7... Abec 9 bearings are used in critical aerospace and instrument applications. There are not many bearing manufacturers in the world that can make Abec 9 as most do not have the equipment and yet you see Abec 9 bearings readily available in skate shops at low prices. A real Abec 9 bearing would cost 30 to 40 US Dollars or more. I leave you to decide!! Have a look at http://www.smbbearings.com/Framesets/Skate_Frame.htm for useful info about skate bearings. #1 bones Swiss #2 bones reds #3 speed demon #4 blind #5 abec 9 #6 abec 7 #7 abec 5 #8 abec 3 #9 abec 1 #10 jc (walmart sold skateboards) *bones ceramics are much faster than bones Swiss but they can shatter*
depends on if there clean oiled and not rusty if theyr new usually 30 secs
These bearings are better value than Reds.I have Abec -5 amphetamine bearings and my 50mm wheels spin for three minutes flat.They are really cheap, and i expect the gold and silver to be alot better. I'd recommend
