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: I have these skateboard wheels with bearings that have been used for FOREVER, they have probably been in these wheels for more than two years. And this skateboard has been left out in the open all of the time, so the bearings are really really dirty but not too rusted so I am going to try to use them in some different wheels. I have tried to get them out with a screwdriver and using the axel on one of my trucks, but it is so stuck in there with dirt probably that it makes it really difficult to get out, even when I apply a lot of pressure. I don't think it is physically possible for me to get it out with just human force, or maybe it's just me, idk, I have tried and tried and I've already broken one nail trying to get these stupid bearings out and I just want an easier way. What other things can I try to get them out of the wheels? I think they are still usable, probably they just need cleaning.
- If you are going to wash the bearings properally then try putting the wheel and bearing in boiling water to soften the wheel, then get a bolt with a head that fits over the bearing but inside the wheel and hit it with a hammer, WD-40 helps to loosten them too, ideally you would need a press.....but i dun think you've got that. when pressing the bearing try to put the pressure on the innner race (the inner circle bit) as not to warp them. if they have been out in the weather for too long they might be buggered, soak them in some petrol for a while, and exercise them (spin them round) a bit, blow some air through them if you can, then oil them up with a really thin oil, there is also other stuff you can use to clean them, there might even be proper cleaning solutions, but petrol works well, or even turps. wear some gloves but, cos it can sting ya hands and it's not good for you.Just persist with the bearing mate, try not to twist it side to side in the wheel, cos that could get it stuck. Hope that helps.
- Q: Well i recently bought a pro scooter and bout ABEC 11 bearings. I want to know if the higher number is better or the lower number?
- ABEC numbers are nonsense for skates, boards, or scooters. It is a number for vibration in high speed industrial equipment at speeds that would be past 200mph on a board. It can actually be detrimental since the smaller tolerances that are required for the higher numbers by the spec can mean more friction. Bearing friction is way less than the drag caused by rolling wheels. The top of the line bearings actually do not have an ABEC rating since the companies are designing them specificaly for human powered motion and have opened up some of the specs to reduce friction while keeping other parts tight.
- Q: or witch hazel? im just looking through my cabinet and seeing what i have....
- my god, both people just told you to use wd40.... jesus christ... do NOT use wd40!!!!!!!!!!!!! ideal way to have your bearings get ruined. 50% alcohol is a little low, could have impurities which can ruin the bearings as well. your best bet is 70%+ isopropyl alcohol (preferably 96% or higher). it really only costs 3-4 bucks. also gasoline works to clean the bearings. then once they have soaked in there for a long time buy some bones speed cream, and apply one drop to each side. never, ever use wd-40 on your bearings. they will speed up temporarily and then get wrecked.
- Q: I want pro bearings that would be kinda cheap and i found these
- Kyle Take off the wheel Look at the bearing, there should be a 4 digit number like 6008 That's your bearing size If there's no number you have to measure the outside and inside diameter with a vernier caliper and plug the size into google to get which bearings you need. But probably standard skateboard bearings most likely.
- Q: what year did they come out with them? i know swiss came out in 83
- Bones Swiss bearings came out in 88. There were other Swiss bearings on the market, though. Reds are much newer, coming to market in the early 2000s
- Q: ive been skateboardoing for about 1 year and my wheels are kinds slow so i would be pleased if you teach me how to clean bearings ty!
- If the bearings aren't sealed, blast the insides where all the little ball bearings are with a degreaser spray, or WD-40 if you have no degreaser. Repack the bearings with some white lithium grease. You can get that in a small tube for a couple bucks--plenty to do all your bearings with.
- Q: How do i change the wheel bearings on a four-wheel drive 96 jeep grand cherokee?
- pull the wheels first, then you will have to remove the caps on the axles ( front ones ) , there is a tool to remove the nut that holds the wheel bearings in place , you have to remove that, the brake calipers and rotors will have to come off too, the rotor has the wheel bearings inside of it, the outter and inner, , use new bearings -they usually are under 30 bucks for the front bearings, and about the same for the rear bearings, the rear bearings are on the drive axle, so you will have to pull the axles to have the rear bearings removed, and they are pressed on, so you will need to take them to a shop with a press for r/r of the wheel bearings
- Q: how to replace front wheel bearings on AWD vehicles?
- Depends on the make. You have to remove the steering knuckle then depending on the make remove the screws that hold the hub assembly and change it. Though some you have the have the hub pressed out, then the bearing pressed out, then pressed back in one then the other,
- Q: Okay so I wanna clean out my bearings, but I dont have any rubbing alcohol, but I do have hydrogen peroxide...I was wondering if it works and how to use it. Plz tell me asap!!! also, does sewing machine lube work to lubricate the bearings?
- first of all NEVER use things like hyd. peroxide or sewing machine lube or WD-40. it clots up, collects more dirt and actually can cause more friction between the ball bearings and the shell. and absoloutly never use water, unless you want rusted shackles. only use actual skateboard lubricants, top kind out there right now is Speadcream by Bones.
- Q: i heard people said it makes it stronger. but i dont know if they meant only to put the wheels inside to make the wheels stronger. because i dont want to break my bearings.thankz.
- yeah i put my wheels in the freezer every time i get a new pair, i would recomend putting the bearings in but when i freeze my wheels i freeze them in a solid block of ice for a month. i dont know if it works but ill take any advantage i can get
