Q:are titanium ball bearings 100% titanium?
Our first year engineering student (above) is a bit off. All usable titanium parts are alloys. There is no such thing as pure Ti in commercial bearing use, and it has nothing to do with weight. In addition, Ti bearings must be hard coated to improve longevity since most Ti alloys are comparatively soft. Ti bearings will last longer and provide better corrosion resistance (if you tend to ignore regular maintenance) but they really won't increase performance... most bearings are too close to the center of the rotating object to add any inertial mass to it. In short, save the $30. Use high grade stainless steel balls and build your wheels carefully... whether you are riding your bike OR your board.
Q:The right bearings????
Bones Swiss Labyrinth. With the extra $4 you pay you will cruise longer. I have some on a 27 inch Gravity and they are great.
Q:How do you CHANGE WHEEL BEARINGS on a Suzuki Quad?
Always Go to - Tools - Pullers - Bearing Remover Sets
Q:are abec 5 good bearings?
Abec 5's are a good happy medium
Q:Could this have caused my alternator bearings to fail?
renewing a belt will often put a strain especially if over tensioned on a bearing set in an alternator. it may well be the initial belt failed due to bearings on way out and having a new belt simply hastened that effect. in either case the alternator is defunct. very unlikely ( impossible maybe) to show the new belt was overtightened. I would just wright it off as bad luck. the overheating will occur if you drive without a belt as most belts also drive the water pump ,hence no cooling.
Q:how are these skateboard bearings?
no, one cost way to much i've never paid over $40 for swiss bearings. They'll both feel and skate the same no point in getting the more expencive ones.
Q:What is a quick and effective way to clean your roller hockey skate bearings?
Nope, to clean your bearings don't use WD40. My dad once suggested to me to clean and soak them in kerosene or gas. clean all of the dirt/grease ect from the bearing and replace with some new. don't forget to clean your bearing casing. but yes cleanindividuallyy is a very effective!
Q:will petrolium oil lubricate my longboard bearings?
Your skateboard should have sealed bearings that you never oil. If the bearings are bad replace them, they are cheap.
Q:some good teaching MOTIVATION or VISUAL AID on "BEARINGS" (trigonometry)?
Visual Trigonometry
Q:which climate cause skateboard bearings to spin faster in the heat or in cold climate?Does heat cause bearings
It depends on the type of lubricant in the bearing. At higher temperatures the viscosity of the lubricant will be such that it moves through the medium faster. Higher temp, faster.
