Q:How can i clean my skateboard bearings?
just get an hot wet towel and wash it off.
Q:What is the bearing capacity of needle bearing and copper sleeve?
What do you mean?Needle roller bearings or rolling friction, copper sleeve is a sliding friction, copper is a set of friction is normalAs for other forces, I don't know what the difference is
Q:changed rod bearings can affect timing? plus a timing memory refresh?
why did you touch the timeing to put bigends in,if you didnt it wouldnt change by itself
Q:How do take apart RollerBlade Bearings?
You don't need to ask the same question in three areas, two of which aren't appropriate. Are you asking how to take the bearings out of the wheel to replace them or how to open them up to clean or oil them? Unlike a couple of people have said, inline skate bearings are NOT sealed. Sealed bearings have way too much drag for inline skate or skateboard use. The method of removing from the wheel that one of them posted is just as wrong. Please clarify your question. If you want to remove them from the wheel, are the axles 6mm (1/4) or 8mm (5/16)? If you want to open them up, do the shields have a rubbery surface or metal surface? If they have a metal surface, are there a row of visible notches around the outside of the shield? Then I can tell you what you need.
Q:How do you take out a front rim bearings?
You'll need a tool called a slide hammer and the proper associated fittings to remove rim bearings. Personally, I wouldn't reuse bearings that were removed. These are often cheap enough to just purchase new without worry that soon you'll be replacing them soon. Since you're dealing with bicycle bearings, they're going to be pretty cheap. Industrial and vehicle related bearings will cost more. The slide hammer attachement basically grabs the bearing pack from the inside diameter where the shaft would slide through. the attachment is connected to the slide hammer. you hold the rim down and slide the hammer weight towards you or upwards in a fast motion.
Q:How does a jet engine remain lubricated it its main bearings?
Oil lubrication is done by dry sump - Dry sump for jet engines (separate oil tank) - Typical oil tank capacity of a JT9D engine is 25 liters - On jet engines - oil is prayed on main bearings then scavenged back to the oil tank - Oil in jet engines is cooled by a fuel heat exchanger (radiator) - Jet engines only use synthetic type oils - such as Mobil II or Esso/Exxon 2380 - Note to Piero - As you know, main bearings leak oil when engine failed and is windmilling - In case of absence of bleed air pressure -.
Q:Can i clean my Skateboard Bearings with Hair Clipper oil?
Q:Do you ever need to clean your bearings on your skateboard? If you do, then do you need to put oil on it?
i've had the same bearings for about 5 years and the only reason why is because of my bearing protectors. i have never cleaned them but i need new ones now. i dont think you should clean them. you should probably buy bearing protectors and you'll be fine. my board has been waterlogged about 3 times and my bearings still survived because of the protectors. well gl skating
Q:Are car wheel bearings actually part of the wheel, or are they part of the axle?
most bearings are a sealed unit . its the hub and bearing together the part is behing where the lug nut studs are if noise was in the front you rotate the tires and still hear the noise its going to be the hub bearing. also notice if the pitch of the sound changes when you turn if it does another indication the hub bearing is bad
Q:Do i need to clean my bearings?
Oooo guy, cleansing bearings is a tricky interest. ok 1st, dont pour a answer/water/something liquid on them. it can cause them to rust up and that wouldnt be relaxing. in case you pick to bathe the exterior of them whilst their nevertheless interior the wheel, what i do is take a toothpick and in basic terms scrape off the airborne dirt and dirt and grim. it works surprisingly darn nicely.
