Product Description:

Specifications:


Needle Roller Bearings (needle bearing) is a cylindrical roller with roller

bearings, relative to its diameter, roller both thin and long. This is called needle

roller. Despite having a smaller cross-section, has a higher load bearing capacity

equipped with a thin and long needle bearing roller (roller diameter D≤5mm,

L / D≥2.5, L is the length of the roller), so radial structure is compact, its

diameter size and load capacity and other types of bearings, minimum diameter,especially for radial dimensions limited support structure.

Q:Where can I get carrier bearings for an 08 ford fusion without buying the whole drive shaft?
From Ford buying a new carrier might mean buying a driveshaft with it if they know it's an issue and they think the driveshaft is causing it. I really don't know. The bearings might be available from an auto parts store by themselves. You can get used carrier assemblies with the bearings in them from a salvage yard or Ebay. The carriers fit multiple popular Ford vehicles so they're everywhere. Call around and ask. BTW it's a little odd that a 2008 vehicle would need axle carrier bearings already. That's not a part that fails with any frequency at all. Unless you put on about 200k miles or drive it hard I wouldn't expect them to go bad. I'd file a complaint with safercar.gov just to cover yourself since if they were to lock up or toss the driveshaft it could cause an accident. You can call Ford(main headquarters) directly and tell them it's unusual for this to happen and see if they'll pay for all or part of the repair.

Q:How long do you soak bearings in gas? ?
Fred, You should never soak any type of bearing sealed or otherwise in gasoline. Bearings and their races are very hard. Without some kind of lubrication they would be ruined in minutes. For you're skateboard the hot ticket for ultimate speed would be an aerosol spray can with suspended Teflon. You must repeat this after a day's use. It's still available although a bit hard to find. I recently found some on line. Just type in: Teflon spray. The next best item for load carrying bearings would be lithium spray grease. It may not be as fast but ambient temperature doesn't thicken this type of lube. It also would give you more protection over a longer period of weeks.
Q:The guy at the auto shop said my wheel bearings have 'play'?
You didn't say what kind of car. If front wheel drive, it is unlikely you have play unless it has lots of miles. If rear wheel drive, you can have play, but almost anybody can grease and tighten them. So it depends.
Q:Did the bike shop screw up my bearings?
The tech really should have looked further. My guess is that the reason your axle was loose is because either your axle is bent, the bearings are toast or your hub is shot. Unfortunately, these things often go hand in hand. Here's the progression in a worst case scenario... 1) The bike is ridden in a manner that causes the axle to bend; 2) With the axle bent, the bearing cones are compressing some of the bearings and crack one or 2 of them; 3) The pieces of the cracked bearings get jammed between the good bearings and also crack those, plus they jam themselves into the races of the hub destroying the bearing surfaces. Yuck.
Q:Cost of replacing wheel bearings?
Mine were looking to be 205 a piece but mine were on a suv to. But a a sable I bet your lookin about 125-150 a piece. As for the response above he is talkin about a c-v joint not a u joint. a u joint is in the drive shaft not anywhere near the wheel. I would suggest getting the bearings and c-v joint check as it could be eaither or
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:tandem axel trailor bearings?
If the heat was caused by the bearings, they should be slightly discolored. On my tandem axle car hauler, I installed grease caps with zerk fittings on them. Before each long trip, I get out the grease gun and give each about 15 pumps. Since yours gets exposed to water, I would pull all and repack, looking for signs of corrosion, pitting or rust, and discoloration. Replace as necessary with new seals. Get the greasable caps.
Q:How much is a good set of spark plug return bearings? ?
Where I live, the car-owner is not obliged to patronise any particular shop. Go to the next one if you are not satisfied
Q:What kind of bearings and wheels should i get for my new skateboard?
Depends what you want to use the board for. Just riding around the neighborhood you want larger wheels because they ride smoother. For jumps and tricks spitfire wheels are awesome. For bearings i love my ventures.
