Q:Do you must clean the abec bearings in your scooter? And if so when do you clean them?
The preferences are based on what works for you. For cleaning the bearings, I use lamp oil (desented kerosene) because it cleans out anything. I then wash it out with denatured alcohol which also dries the bearings. If you use a water based cleaner like citrus cleaners, do not soak them overnight since it can damage the bearings. Almost anything works for lubricants. Super light things like the sprays don't last very long. Some people spray them every time they go out. Oils roll quickly right away but are not as waterproof as greases or last very long. Greases are slower at the start but will last a lot longer. Use very little. A drop or two of oil or a few pin head sized blobs of grease.
Q:Bones reds vs stock bearings?
bones reds and independent
Q:what types of bearings are used on a 225kW wind turbine?
External bearings are usually long life types and may be sealed or not, usually tapered roller bearings designed for angled loads. Internal bearings can be of several types used in different places. In some cases, bushings, rather than bearings, are used in part or for the whole thing. It all depends on the manufacturer.
Q:Cylindrical roller bearings and needle roller bearings is the same thing?
It's certainly not the same thing. Look at the mechanical manual. Top of it. See what you've got
Q:out of the three skateboard bearings which was is the fastest?
I have skated may bearings in my day and by the far the most bang for your buck is bone swiss chinese reds. They're super fast, durable and easy to clean I have had the pair I am using now for over a year and a half and I skate at least 3 times a week. The best part is they are only about 20 bucks.
Q:Can anyone explain me bearings?
Here's a video explaining bearings. Did you have a specific question regarding bearings?
Q:How often should a cyclist grease their wheel bearings if riding 100 miles a week?
If they feel rough, it is too late. Plan to do it once a year, more often if you ride a lot in the rain and dust. I ride 2-3k miles a year. If the ball or cones are pitted, replace them for a few bucks before the hubs get damaged. If you are not very concerned with top notch performance of your bike you can wait longer but a buck of grease can save you lots of grief.
Q:Can I put X-TRA HEAVY DUTY GREASE on bearings?
You can, but it would be a bad idea. Bearings require lubricants based on their use. Grease is used where the temperature is high enough to liquify the grease to the proper viscosity. Also, if your skateboard has exposed ball bearings, the grease will collect and hold dirt, which will then act as a grinding compound and wear them out. If the bearing are sealed, no lubrication is necessary.
Q:How do you pack trailer bearings with grease?

Q:what trucks, wheels, bearings should i get for my skateboard?
i have bones red bearings and they've always been as good as when i first got it.it depends if you ride loose or tight trucks. if loose, i suggest venture because there naturally loose and that's how i ride. if you ride tight trucks you should get silver trucks.if you want speed you should get pig wheels or spitfire. if you want grip you should get ricta or pig.
