Q:how can i make my skateboard bearings cleaner and faster?
graphite okorder.com)
Q:2001 ford escape wheel bearings? (rear)?
Do not buy cheap mechanical parts...you will pay dearly for those cheap parts.
Q:Does the Firedog yoyo have bearings?
Yoyo's have bearings? Then they don't work like when I was growing up - how would a bearing unit grab the string to climb it.
Q:Ford F150 Repair Question. Transmission/Bearings?
Also, you never said what the problem was that you had with the truck. My psychic powers are not working today. Sorry. lol Take it to some small shops and get an estimate and also to see what is wrong.
Q:Is Dragon bearings good?
i've never heard of dragon bearings but some really good quality bearings are china reds. and they arent to expensive. personally, i dont think element is a good brand. my friend had one and the board was horrible. it had no concave at all (a flat peice of wood) and it broke really easy. me and my friend both have enjoi boards currently and he says its way better than his old element board. i suggest Enjoi
Q:bearing spacers on my Rollerblade spark makes removing bearings difficult.?
He changes a lot of wheels when he sets up a booth at events and can pull bearings much faster than explaining how. Use a bearing tool or other object that fits inside the bearing. Just put it in as far as the bearing and lean it to a side to put force on the bearing. Make a rolling motion around a circle with your hand and the bearing will walk out of the wheel. A cruder, brute force, method is to take a screwdriver handle from a 1/4 socket set and put it into the bearing hole (it will just fit). Then twist sideways until the bearing pops out. Most better quality skates have gone to the 8mm axles and the rolling motion is a good method to learn.
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 are wear limits on bearings determined?
General ideas only. In the case of journal bearings with forced lubrication (oil pressure), increasing clearance results in oil pressure drop. Ideally, journal bearings hold an oil film which supports the rotating shaft and minimizes metal/metal contact. Automobile engines run for hundreds of thousands of miles using this strategy. Radial ball bearings will tolerate excess clearance (depending on the load) but the shafts they support often will not. In cases where oil seals are used, excess shaft play damages seals and permits leaking. In the case of motor or pump shafts, bearing slack permits rotor/stator contact or impeller/involute contact. Rotating masses are never perfectly balanced or axially aligned. Bearing slack multiplies unbalanced force and consequent load.
Q:Which skateboard bearings shall I get?
I used to skate before my knees gave out and I would have to say Bones Reds or Swiss if you can afford them.
Q:i have a question about skateboarding bearings?
Abec 3 is no good, just get bones redz. They skate good and theyre like 15 dollars
