- Q: What bearings should a beginner have on their skateboard?
- For a beginner you should just stick with the ones the board comes with
- Q: I need to buy bearings but I dont want to get the wrong one
- 608 STANDARD The most common bearing size is the “608.” Characterized by an 8mm core, a 22mm outer diameter and a 7mm width, these bearings are the industry standard and match up with nearly every skate wheel out there. There are also mini-bearings that can be used with the standard 608 bearing hub, but they require a sleeve to make them compatible.
- Q: idk if yhe bearings will fit or is it like all lonboard bearings are universal and can fit in any longboard wheel. also can you show me some bearings that fit in theselinks WHEELS
- all bearings are universally sized. any longboard bearings you get will fit the wheels fine
- Q: I need to clean my skateboard bearings but im not sure what type of liquid i should use to clean them?Acetone or Mineral/White spirits?
- No bro! NEVER! EVER! Use WD-40! Maybe just a 5 sec dip BUT NEVER USE WD 40 ON BEARINGS! It'll eat right through it! Use maybe acetone.. its less acid but is still a bit hard.. I usually clean mine by rubbing them with tissue, then put some oil on the tissue and slightly pass it throught.. not to get the liquid stuck in between..
- Q: the bearings are abec 3's and they just dont seem to go as fast as they used to. any suggestions on how to make them go faster?
- Get some bones bearing lube. Take the sheilds off the bearing if they have rubber sheilds you can just use a pin or something small. If they have metal sheilds dont try to take them off just wash them from the side without the sheild. Wash the bearings out with water and spin them a bit while you wash them. After that get a cup put some water in it and put any kind of cleaner in it and swish it around a bit then leave them soaking in it for like 10 minutes. After your take them out of the cleaner wash them in water one more time get all the cleaner out then leave them to dry 100%. After that put 1 or 2 drops of bearing lube in each bearing and put the sheild back on and your ready to go.
- Q: How much speed can the needle bearing of inner bore 17mm bear?
- This depends on the lubrication, lubricating oil viscosity, pressure is different, allowing the speed is also different
- Q: What exactly is the difference between sealed bearings and regular bearings and sealed pedals and regular pedals.
- Sealed bearings require no service. Once they are installed, you use them until it's time to replace them. Regular bearings should be disassembled and repacked with grease from time to time. Sealed pedals have sealed bearings. Regular pedals have regular bearings. HTH
- Q: A ship is sailing through the water i the English Channel with a velocity of 2 knots along a bearing of 157 degrees. The current has a velocity along a bearing of 213 degrees. The actual velocity of the ship is the vector sum of the ship's velocity and the water's velocity. Find the actual velocity.Ok so i understand how to do the actual problem, I just have no idea how to convert the bearing degrees into standard form so i can do the problem. I looked at my teacher's review and she gave the standard form for the bearing of 157 degrees as 293 degrees, and the 213 degree bearing as 237 degrees. Well I looked at them and found that the both add up to 450 degrees which i thought might be the solution, but I looked at another problem that had a bearing of 60 degrees and standard position of 30 degrees. Thanks for any help in advance.
- true bearing is a navigational angle. it is oriented such that 000 is at due north, and it increases clockwise. a mathematical angle is oriented so that 0 is at due east and it increase counter-clockwise. as a result, the relationship between the true bearing and a mathematical angle is A1 = 90 degrees - A2 where if A1 is the navigational angle, then A2 must be the mathematical angle, or if A1 is the mathematical angle, then A2 must be the navigational angle. That's why bearing 157 degrees = 90 - 157 = -67 degrees = -67+360 = 293 degrees and bearing 213 degrees = 90 - 213 = -117 deg = -117+360 = 237 degrees === so as long as you convert bearings into mathematical angles, then you can resolve vectors into (x,y) coordinates using the standard transformation x = r cos(t) y = r sin(t) where r is the magnitude of the vector and t is the mathematical angle. otherwise,you have to use x = r cos(90-t) = r sin(t) y = r sin(90-t) = r cos(t) where t is the bearing
- Q: I had found out bones reds are one of the most best bearings for the money, and lots of mates have them so I bought some bones red's from Trademe (the New Zealand version of ebay) and they were real and all. as soon as I got them I rode them all around. but after about a week they were worse than my abec 3's. So I changed Back to them. While I was at the skate park People were saying that bones reds just need wearing into. so I cleaned them by soaking them in turps then putting speed cream on them. I have been skating heaps this month. but still not beta...???So any advice or help of what im doing wrong would be appreciated
- Don't buy anything from anyone you don't know. Never buy from Trademe or eBay because somehting might be wrong with it. If you're going ot buy online then go to a trusted skatesite or a skateshop. Your Reds are probably dented causing more friction. Just pick up some FDK's ($10 abec 3's) or some new Reds.
- Q: what is the diffrence between thrust and radial bearings?do redial bearing allow motion along the axis of the bearing?don't thrust bearing allow radial forces?i am confused, and i need some insight
- I okorder /... which turn out to just be what I think of as normal or traditional ball bearings. No, radial bearings do not allow motion along the axis - normally there is a stop on the shaft to prevent this and continuous movement would damage the inner surface of the race or the shaft. Depending on the type of race, having any significant axial force would damage the bearing, as would occur in moving the shaft axially. Thrust bearings in theory are entirely for taking thrush along the axis and properly positioned radial bearings handle the radial forces of belts, chains, wheels, etc. A roller bearing or taper bearing would be used to handle both in one location. In practice, a thrust bearing with a ball race of the right shape will handle radial forces of a significant fraction of the rated thrust.
