Q:is it good to have openings on your longboard bearings?
Providing you keep the shielding on the one side facing outwards. They should be fine like any other bearings, easy clean and lubing. However you'll have to service them more often. Buddy of mine has a similar case with the bones reds and they work superbly like any bearing out there. Either way your longboarding experience is not going to be affected by it in anyway.
Q:i have a question about skateboarding bearings?
Good bearings don't have an ABEC rating, just get Bones Reds or if you have money get Bones Swiss. They go hella fast and are way better than most bearings. If you have to get an ABEC bearing get 7s
Q:Longboard bearings question?
Little room i try to keep them even not to mcuh or your have troubel trunring snd axle slip
Q:Are Rush Bombers good skateboard bearings?
No the bearings to go with are red swiss bearings. They are sick and last forever.
Q:What are the symtoms of bad main vs rod bearings knock?
Yes, if your going to replace the rod bearings then change the main bearings as well. You can replace both of them without removing the engine if you know what your doing. Remove the main bearing cap and push the other half out by rolling it around the crank shaft. Easiest way to tell which it is, start engine and get noise to start. Pull spark plug wires one at a time, then reinstall. If the noise goes away at a certain cylinder then you found the bad rod bearing. If that doesn't work then it is most likely a main bearing. Only problem with replacing them in the car is you can't properly check bearing clearances on the crankshaft. Good luck
Q:Bones reds vs stock bearings?
bones reds and independent
Q:What is your favorite skateboard bearings and why?
Bones Swiss bearing are a good quality for skateboards. Good for you that you have that in your deck.
Q:What bearings for inline skates are the best?
A because he is local and I can get them in person. He has several levels of ZeroDrag bearings that compare well with anything on the market. If your wheels use the 688 micro bearings (only in common use on some roller hockey wheels) your choices will be very limited. The 688's were popular on fitness and racing skates a few years ago but were found to not have the promised advantages and people complained that they were not as durable when subjected to outdoor conditions than the traditional 608 bearings. Most companies quit making 688 wheels and bearings, except for hockey.
Q:Wheel Hub or Bearings??
Well I am not too sure about nissan but I know for certain on the newer chevy vehicles. the wheel bearing is in a hub assembly and the whole hub has to be replaced, probably why people have told you both, cause on newer cars it is the same thing. Best bet you could call a parts store and tell them you need to price front wheel bearing for your vehicle. that will at least give you an idea for the parts end of it. Mind you labor is about 100 to 150 an hour depending on the shop. GOOD LUCK,
Q:Roller blades with sand should I clean ball bearings with (nail polish remover)acetone? (chemistry)?
Absolutely none of the liquids you mention will react with SiO2 or dissolve it. There is nothing that will dissolve SiO2 that won't also dissolve your bearings. The point of the various bits of advice is that the acetone (or whatever organic solvent) will dissolve the lubricant in the bearings which is holding the sand grains there. Whether you use nail polish remover, or acetone (diluted or not) or gasoline or kerosene or maybe even alcohol doesn't much matter. (Although in all cases you need to observe the safety precautions about inhalation and fire hazards, and keep the solvent off of the upper parts of your roller blades.) Your goal is to remove all the oil (or whatever lubricates your bearings) then let the bearings dry completely. Then you should be able to remove any left over sand by brushing it out of the bearings with something like a soft brush or blowing it out with compressed air. After all the sand is removed, you need to re-lubricate your bearings. (I've been assuming all along that your bearings are metal. If they are not, you need to be careful about your choice of solvents, lest you dissolve your bearing too.) I doubt there is anything else you can do to remove sand from your bearings. In the long run it's probably easier to find a place to roller blade where there isn't so much sand.
