Q:what does ABEC 7 Speedster bearings mean for roller blades?
It basically means nothing. The use of ABEC ratings was an accident in inline skating. It is about bearings used in machinery that runs at extremely high speeds. Nothing about rolling better under the weight load or speeds for inline skating. Some of the bearings used for the early inline skates were so poor that any ABEC rating guaranteed that the bearings were reasonable. Then the manufacturer's got their advertising people into the act by bragging about a number that isn't important or expensive.
Q:I have a Dynacraft Next Turbo bike,I have called on the cycle companies and said I would need to call the Next company.So I was wondering,what are the crank bearing sizes for the bike? Thanks!
Try okorder ( don't forget the dash in between the words )
Q:a boat sails on a bearing of N15E for 10 km then on a bearing of S85E until it is due east of starting point the distance from the starting point to the nearest km is thena. 10 kmb 38c. 110d. 113e.114
My answer is a. I plotted the bearings on a plane: starting point is (0,0) and got (15,10), and (85,0). This means the first distance traveled by the boat was the nearest distance to the starting point.
Q:About how much would it cost to hire a mechanic to change my pistons and or my piston bearings in my 1998 Pontiac Firebird 3.8L V6?????
there is more to it than that, first of all if you need pistons and bearings then more likely than not there will be excessive wear on the crankshaft, and also you are going that far, the heads should be rebuilt, because putting a new short block, with old worn out heads, invites more problems. Besides, it would be cheaper for you to buy a long block, and have it installed, than pull the motor and take it apart, add a few parts and put back together an undependable collection of old and new and worn parts. Personally I would put a later model 5.4 chevy small block engine, transmission with the wiring harness and computer. this will make a screaming quick firebird, with about the same fuel mileage.
Q:What are the differences between cylindrical roller bearings and needle roller bearings? In particular, if the roller and needle diameter is about the same, cylindrical roller bearings and inner ring needle roller bearings seem to be difficult to identify it
Back to the 2# plane thrust roller, there are also, such as K811, K812, K893, K894. The first two are single row roller, K893 and K894 are double row roller, these are thrust bearings, INA code name, you can scroll down the directory
Q:i am a beginner skateboarder and i am going to buy a skateboard and debating whether to buy cheap trucks and bearings and save money or to spend more on a little bit higher quality ones. i am just a beginner so i dont know whether i would even tell the difference. if you think i should get better ones can you recommend any to me?
Ok so first off don't buy cheap made trucks or bearings, I've had cheap bearings there slow, get dirty fast, and all my abecs fell out. And I've never had problems with trucks but I've heard of them snap and alot of other bad things. Secondly, buying better quality will last you a butt ton longer. Some brands of trucks are: Independent,Thunder,Theeve,Tensor,and Venture. Some bearing brands:Bones,Shake Junt,Spitfire,and Shorty's. P.S. get Bones Reds bearing their cheap but last at least a year or better and their really fast. Hope this helped.
Q:i have an 2001 ford ranger and it sounds like a bunch of rocks or marbles sound coming from my rear wheels. does that mean i need new bearings?
If the noise increases with speed yes, check your rear differential to see if its low on fluid and get the bearings changed out. Bearing seals also may be leaking diff oil over your rear brakes.
Q:I've been using just reds for a long time now and I think it's time to upgrade hah. Are bones swiss bearings much smoother and faster than just reds?
Just get the Bone swiss. As long as You movin you good! Btw My friend makes bearings faster then bone swiss. He sells em for around 30 bucks. He gave me a pair since i skate with him. If intrested PM me
Q:2002 mercury cougar wheel bearings need to be changed, what tools do I need? And I don't think it matters but it is a 2.5 liter.
This is not difficult but if you have never done it I would suggest having it done it would not be expensive. You have to know how to pack the bearings with greese before installing.
Q:this: http://www.narzedzia.pl/photoShopVariant/large/804_Szlifierka_k%C4%85towa_HSW_3125CE.jpgmodel hsw3125CE
if this is a family heirloom take it to a tool repair shop and get a bid, or take the bearing out and take it to a bearing shop for a price check.
