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.
The draw up needle roller bearing has two structures-with retainer and with full of needles. They are are divided intoopenend type and close-end type. The structure with retainer has the single seal ring and double seal ring .The structure with full of needles has a large load carrying capacity.

- Q: I went and had my local bike shop put a new freewheel on my bike today. While he had the wheel off he wiggled the rear axle, told me it was loose, and offered to adjust the bearings. Now my back axle makes a pinging noise while I'm riding. The noise is gone when the bike is on the stand with no weight on the axle. Can this be fixed and how much will it cost?
- 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: For my college engineering design project my team is basically designing a mousetrap car that has to travel a minimum distance of 3 meters and the dimensions are 20cm X 10cm X 10cm. The car will rely on its coasting phase to travel the majority of this distance so the reduction of friction between the axle and body needs to be at a minimum. I was thinking of using ball bearings for high quality rc cars but the only problem I face is how to keep them in the body which is basically a sheet of aluminum with two 1 cm edges bent 90 degrees downward with an 8 cm hole drilled through each side for the axles (od of bearings is 8 cm). I was thinking of using epoxy to keep them in but id like to hear other opinions.
- but it may overcomplicate it, unless you can use the complete wheels with the axle. .
- Q: Recently started getting alot of noise coming from the front of our truck. The sound is like a high pit ch noise the gets louder as the truck picks up speed. I would best describe it as a high pitch or like the sound of really big 4x4 tires as they drive by you on the freeway. I did the standard wheel bearing check. Jacked up the truck and pushed and pulled on the wheel. I get no shake or looseness. I can say that the passenger front doesn't roll as smooth as the driver front. I pulled the hub off and did a close visual and i can see nothing wrong. No leaking, scaring, or looseness. Just the lack of rolling smoothness like the other side. Could this be a bad bearing?
- It could be but it can also be dry bearings. Did you grease the bearings while you had the hubs off? If not grease them if the problem doesn't go away I would then replace the bearings. Bearings are fairly cheap so for your own peace of mind you will know they are OK. I hope I have helped you.
- Q: I got a frame. But it looks like it uses a different size than an easter bike
- You may need to be more specific with the question but i assume that you are talking about the bottom bracket bearings. In BMX there are various BB (bottom bracket) sizes there are, Euro BB, Spanish BB, American BB and Mid BB. The most commonly used BB is the Mid which most BMX frames use now days, the American BB is quite old and dated the other BB that you may see is the Spanish BB which is used by various companies one being Fly Bikes (being a spanish company). You may find that your Hoffman frame has a Mid BB and the Eastern frame you own has a Spanish BB the most common difference is the Mid is larger than the Spanish, unless you provide some more information i suggest that you go to your local bike shop and ask for their opinion or help. Good luck!
- Q: i have removed the rear wheel and centre cap do i need to remove the drum
- yes, and chances are you will need to remove your axles and use a slide hammer to knock your wheel bearings out if this is a solid rear axle vehicle. when your remove the axles make sure they are not grooved where the axle rides and that the axles tubes aren't full of metal material.
- Q: I have a 1992 Camaro RS, LO3 305 TBI V8, Automatic, 125k miles. It had the oil changed awhile ago, not sure what they put in it, but when I picked it up, the engine was ticking (sounded like a lifter or failing oil pump). I've driven it a few thousand miles and it runs good and strong, but I've always noticed that the oil pressure guage reads low, between 5-25 psi. I'm concerned my bearings are shot. It normally starts up at 25psi and after driving 10-20 minutes, it reads 5-10 psi, and the ticking becomes slower. The engine never kills though. Could it just be a case of a bad sending unit, with to light of a weight of oil, or bad bearings? What are some common signs of bad bearing? The motor does not knock.
- if your bearings are bad your engine would be knocking and would soon stop. it sounds like your bearings are worn which would give you low oil pressure. I would run the oil made for older engines that have wear like yours.and by the way try not to beat it to much it'll last a little longer
- Q: I need to get my honda aquatrax trailer's bearings greased up and I'm no handy man. I don't know if the PWC (jet ski) dealer (also a motorcycle dealer) would be willing to do it or if i have to go to a car mechanic.
- your marine service shop should be up to the task of maintaining your marine trailer too. if they arent, you shouldnt be going to that shop to begin with. any normal car mechanic should be able to handle it too. its actually a very easy job, if you dont mind getting grease on your hands. wheel bearings are wheel bearins are wheel bearings..... and there are also places that deal more specifically with trailers. they would be able to handle your marine trailer maintence too. i would suggest you add a set of bearing buddy caps to your shopping list for parts. they have a fitting on them that allows you to pump grease into them without popping them off. and a spring that forces the grease through the bearings and out the wheel seal (if over pumped you will ruin the wheel seal). just pull off a little plastic cap, check that the spring is half compressed and you will have no bearing worries ever again. if the spring is ever getting relaxed, pull out the grease gun and give it a few pumps. bearing buddy caps claim to be a final solution to keeping the bearings full of grease and working properly. IF used properly and kept full, that claim is true.
- Q: I have a 2001 Nissan Maxima Se, when i jack tha car up (on the driver side) my wheel is loose, obvisouly with the lug nuts screwed all tha way in, i talked to a few people, but they sed it could be my Wheel Hub or my bearings, i don't know, i just don't wanna get robed blind, wat would be a reasonable amount of money + labor to fix either tha hubs or tha bearings on tha one side???
- Well I am not too sure about nissan but I know for certain on the newer chevy vehicles. the wheel bearing is in a hub assembly and the whole hub has to be replaced, probably why people have told you both, cause on newer cars it is the same thing. Best bet you could call a parts store and tell them you need to price front wheel bearing for your vehicle. that will at least give you an idea for the parts end of it. Mind you labor is about 100 to 150 an hour depending on the shop. GOOD LUCK,
- Q: What is the best deck, bearings so on so on. I am a begginger. Also what addvice do you have to me.
- listen up kiddo cuz i know what im talking about. First off, there are two good beginer's boards. Zero, which is my personal favorite, and Alien Workshop, which I've heard a lot of good things about. Alien Workshops are over all good boards, and zero is good for street skating and getting high ollies. The next thing, is trucks. I think that the top trucks brands are Krux, Grind King, and Phantom 2. But really, all the trucks are virtually the same. You can ask anyone, Zero Black Widdow Bearings are the best.... Spitfire wheels are the best wheels... Stay away from brands like Blind [which cracks easily] and Birdhouse [They are designed for vert skating, and are VERY VERY hard to ollie with because they are really heavy.] Also element are generally cheap and flimsy. Shoes are all the same, just pick whatever looks good. ^__^ If you already know how to ollie, thats great [Push down with your backfoot on the tail of the board, and slide your front foot up the board and jump]. But it takes a while to ollie, so you really need to keep practicing as much as possible [It took me around 2 months to finally ollie], and watch as many skate videos. If you follow those two things, you will be ollie-ing in no time. good luck.
- Q: how do u clean skateboard bearings?
- you take s socket wrench and loosen the nut and take it off and take off the washer , than the wheel than the other washer . Don't lose ur washers !!! Do this to each wheel . Take about 8 Qtips or more or less depending on how dirty ur bearings are , take the Q tip and rub the dirt off of the bearing . Each side and in the insides .
