- Q:i want which provides us about bearings that means i have seminar on ISO standards--Roller elements bearings
- I have seminar too. So I want that which means seminar ISO standards Journal Bearings, so that makes it OK.
- Q:can skateboard bearings fit in scooter wheels
- yes skateboard bearings fit into scooter wheels to but i prefer to get swiss bearings cause they go on forever
- Q:And can u also tell me how to clean abec 9 bearings? and grease 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:ok ever one says bone swiss bearings spin for ever!!! well i just got a brand new. apsolotly fresh out of the case bones bearings and i put em on my board and they only spin for 12 seconds!! when i skate with them will that losen em up?? if you have bones bearings, how long do yours spin? and how do i make em faster
- 37 seconds after cleaning and re-lubing. Haven't been broken in yet. Make sure the shields are not dented. they should be flush with the outer race of the bearing. Test: setup Bones Swiss bearings Trucks: Indy Wheels Santa Cruz OG Road riders 75mm 79a I prefer Pig Swiss over Bones, had some that were cleaned and ready for a spare set.
- Q:Hi, the question is; A fish swims 2km from point A to point B at a bearing of 30 degrees (measured anticlockwise from due east). It then travels due east to point C for 1km.a) Determine the distance the fish is from its starting point.b) Write vector AB and BC using vector units i and jI drew a diagram, and am completely stumped! thank you in advance! guidance in the right direction is also fine! I just have no idea where to start!
- using compass bearings: (2,60°) + (1,90°) = (2.9093, 69.8961°) - - - - - - (2,60°) = (1.7321, 1) - - - - - - (1,90°) = (1, 0) - - - - - - (1.7321, 1) + (1, 0) = (2.7321, 1) - - - - - - so: a) 2.9093 km b) (1.7321, 1) and (1, 0)
- Q:im trying to lubircate my bearings. and all i have is some gear oil, or petrolium oil. will this work to lube my bearings?
- Your skateboard should have sealed bearings that you never oil. If the bearings are bad replace them, they are cheap.
- Q:nd which is betr bones reds bearings or minilogo bearings?
- BONES IS THE BEST. dont get anything else. theyre the fastest, longest lasting ones ever.
- Q:What bearings for inline skates are the best?
- A okorder ) 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:What skateboard wheels, bearings and trucks for my sons new pool skateboard?
- I assume you already have a board picked out. All my pool setups have Indy trucks (factory yellow bushings) they have great turning response. Trackers are good as well, but are less fluid in turning. Both brands have been around for 30+ years and are designed for grinding pool coping. Leave the trucks set at factory tightness, which is LOOSE. Pool skating is much more enjoyable and by far easier with loose trucks. Make sure to get the correct width trucks for the board. when in doubt, opt for a little wider. Get some risers to reduce wheel bite. As for bearings, Bones Reds are a great value. I know many riders who swear by these bearings. My favorite is Pig Swiss. They require less frequent servicing and roll faster. The wheel choice is really based on a rider's preference. The wheels on a pool board generally are 60-63 mm, as larger wheels are faster. The big choice is wheel hardness. the harder the wheel, the faster it goes; but it has less surface grip so it slides more. Softer wheels are grippier, but slower. They are also better on rough surfaces. My two favorite wheels right now are the Spitfire Jesse Lifer II 61mm 99a and the 60 mm Bullet Church Glass 95a wheels. Much of the pool skating crew rides Santa Cruz OJII or Bones SPF. I prefer the OJs for wooden ramps.
- Q:My last skateboard bearings got thrashed in no time. So i had to drop some more money on new ones so i want to no how to make them last as long as possible.
- Look it up on youtube and it will be easier to follow bc it is a visual video, Compared to writting on here.
