Drawn Cup Needle Roller Bearing :
The outer ring of drawn cup needle roller bearing is punched with the high-quality steel sheet. The outer ring has thin wall.The drawn cup needle roller bearing has the characterstics of small radial section area, large load carring capacity ,less inertia and economic manufacture. It is suitable for small section heght, or when the housing bore isnot used for raceway , this type is recommended to use .The bearing is assembled into the housing bore under a certain pressure without fu rther axial location.
The draw up needle roller bearing generally takes its shaft diameter as the internal raceway .However , the proper LR type inner ring can be used in accordance with application condition.

- Q: This may seem like a stupid question as I am just learning to skateboard.I bought a brand new complete board with abec 5 bearings and they seem quite stiff. Am I suppose to oil them before I ride or do they eventually loosen up as I ride? Also I took the riser pads off because I heard it makes it easier to learn to ollie, will this help me? I have 51mm wheels so I dont think they will rub against the board.Thanks for your help.
- The boards do could desire to interrupt in in the previous you get the optimal sense of it. as far because of the fact the turning is going, you are able to attempt and regulate the tightness of the autos if it would not be sure over the years. The wheels will extremely get greater desirable over the years.
- Q: My car has no oil pressure and they said I need a pump and main and rod bearings. Can I just replace the pump? Or can you tell the bearings are shot by just hearing it?
- That is serious work you're talking about, if you do that you might as well have the entire engine rebuilt. And if you've run the engine at all without any oil pressure there's probably other damage already done to the engine. Overall you're better getting a rebuilt engine or having a junk yard engine and having it rebuilt. That's only if you really like the car. Otherwise it might be time to look for something newer. There's nothing wrong with putting a lot of money into an old car if you really like the car. If you have a connection with the car it's definitely worth it. But if it's just a means of transportation to you, it makes more sense to just get something newer. A bad rod bearing usually is accompanied with type of clicking or clattering sound in correlation to engine speed. You'll have to go off the word of your mechanic. Failure of rod bearings eventually leads to the destruction of the engine sometimes immediate and catastrophic if not taken care of. Good luck.
- Q: I have 8 bearings like any other skateboard. all 8 are crappy because my bro takes it out in the rain. Damn. And one of the 8 is all smashed up(long story). So im riding to school and when at fast speed it starts to wobble ALOT even on flat smooth ground. Would buying new red bone bearings fix this?thanks
- The bad bearing could be causing a vibration, but probably won't cause the board to wobble. Usually bad bearings make noise and don't roll freely. It sounds like you might be getting speed wobble. This is caused by loose trucks at high speed. You can try tightening up the trucks when you go fast, but be sure to loosen them up for other riding. You might want to check for a blown bushing as this could be causing the wobble problem as well. You can also change your position on the board as well when riding at high speeds. Smaller, narrower boards are more prone to speed wobble than longer wider ones.
- Q: are these above, just consumable type things ,that need replacing after time, how many miles for each generally speaking would they need to get replacedwhat are signs that track rod ends have excessive playwhat are signs that wheel bearings have excessive play, and what exactly do they do
- its really tuff to say it just depends on the Quality of the part
- Q: I just bought the sector 9 bambino 26.5 and I was wondering what would be better for it. Im trying to decide between the bones swiss labyrinth would bones super swiss 6. What would be better for my board-thanks.
- Bones Swiss Labyrinth. With the extra $4 you pay you will cruise longer. I have some on a 27 inch Gravity and they are great.
- Q: Some folks say that using them to go through or under the rubber cover on a tie rod end doesn't get grease into the joint itself. Sound reasonable?Many ball joints these days don't seem to be greasable with them at all -- am I missing something?Can the needles lubricate sealed bearings, and if so, what's the technique? Thanks much
- If a unit is a sealed unit, it is not meant to be greased, it is greased for life. The grease used is a little different then grease used in greasable joints. The grease has chemicals added so the grease does not wear down as fast. It is not practle to use this type of grease in greasable bearings, as they are not fully sealed and tend to seap gread from around seals and seams. Since they shoudl be greased every oil change (as a rule of thumb) they tend to keep grease this way. Sealed units don't need to be greased as they are sealed so the grease has no where to go, chemicals are added to keep the grease from breaking down as fast so it lasts longer. You should not have to use a needle through the boot or seam to grease these, if they are leaking or seaping grease, they should be replaced. Sealed units are, in a sence, superior to non-sealed units as they are maintance free and tend to last just as lone, or longer then non-sealed units. Sealed bearings are the same way, the grease that is in the unit is there for the life of the unit and does not need to be changed, and grease does not need to be added. Do no puncture or break seals to any sealed unit , even to grease, this will create a place where grease will start to seap, or it can actually damage the unit, and it will actually, decrease the life of the unit. A sealed unit is sealed for a reason, It is sealed from the elements, and from comtamanents, non-sealed units need greasing because since they are non-sealed dirt and debris can enter the unit and cause wear, greasing these non-sealed units is how the contamants are removed or reduced from the unit. Long story short, non-sealed units, greasing is good for the unit, sealed uints, greasing is bad and can cause damage to the unit.
- Q: So i took my bearings out of my skateboard to clean, and now i can't get them back in! I know that pounding it dents it, because i tried it before and i ruined my bearings. but its too hard to push them back in with my thumbs, i have the hard wheels. Somebody help me!
- Thumbs up for big thats how you should always install your bearings, make sure to press as straight as you can and they'll pop in better.
- Q: i was planning to buy a new bearing, but do they have different sizes? (sure answer pls......)
- Lets see... For a good deck I'd check out Plan B, ZooYork, or Zero they're all 3 pretty good brands. For trucks u have either Silver or Independent, I think Silver is better but that's my opinion. For bearings I'd go with either Bones or FKD saw blade. For wheels Bones would be a good buy as for grip tape u can either check out mob or check out Torey Pudwill's new brand called Grizzly Grip but it just came out recently so it may be hard to find in stores!
- Q: examples.
- Axle wheels on PWC trailer.
- Q: On skateboard bearings what's the ABEC letters mean?
- ABEC stands for Annular Bearing Engineers' Committee. Does ABEC affect the speed of your skates? No. Not unless you are skating at 330 mph. That's based on a 608 bearing limiting speed of 32,000 rpm. Only in extremely high speed applications like ultra high speed motors and precision measuring instruments can bearings above ABEC 1 affect performance. Regardless of how fast you plan to go, speed is affected first and foremost by the choice of lubricant. If we're going to talk about tolerances, the fit of your wheels and axles have a much greater effect on performance than ABEC rating. Wheels and axles for inline skates have extremely loose fits that allow you to press the bearings into the wheel by hand. This masks the benefits of a higher precision bearing by allowing it to slip on the axle or in the wheel. Slippage between the mating parts results in energy loss. Lost energy is lost speed.
