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.
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: my car recently (2 weeks ago started making a knocking noise like a chatter and i hear it coming from the engine. my mechanic said my main bearings are failing. he says the engine will last a couple years if i use a heavier weight oil. 2 years seems long. is that right?
- You can't guarantee anything when main bearings start to go bad. I bought main bearings for one of my cars and put off installing them for two weeks and the engine seized up solid. A truck had bad main bearings so I added Lucas Engine Treatment to see if it would last longer. (I had a spare engine to put in it) Well the engine was still running three years later. I would try the Lucas stuff for motor oil and price out the work with your mechanic. If you get them done soon you can avoid damage to the crankshaft.
- Q: The bearings on one of my longboard wheels got rusted. I feel like it's unnecessary to buy a whole new set of bearings when only two of them are messed up, but it's pretty noticeable. Any hope for fixing them?And don't suggest WD-40. It screws up your bearings.
- I heard that soaking them in Coca Cola will get rid of the rust (but you gotta clean them realllly good after). Otherwise, you can buy another set of bearings, then when some of them rest, mix and match and throw out old, rusted bearings as needed.
- Q: should i put a little grease inside the wheel so the bearings slide in easier? they really dont want to go in strait. should i lay the bearing in the hole and put the nut on and tighten the bearing into the wheel? Help....
- Do not put grease, grease will wreak your bearings. The best thing to do is buy a skate tool that can help you insert them. If you dont want to do that simply put the bearing on the wheel (where it needs to go) and put the wheel on the truck with the bearing still on the wheel facing the truck. Then just simply push down on the wheel and the bearing will pop into place.
- Q: please introduce me useful related web sites.
- a okorder ... they are not hydraulic bearing pullers, they are not hyd clutches, they are not hyd nuts.
- Q: how do i check the main bearings? on my chevy?
- Nick... it's evident from your previous question about the engine being locked up, that you have no engine building experience and this question confirms it. I assume that you have invested a lot of money in parts and machine work and it would be bad to mess all that up by a shoddy assembly job. I suggest that you find a competent mechanic and let him assemble the engine. BUT to answer your question.....you will need to find out the clearance specs for the main and rod bearings. Then purchase several sticks of the appropriate sized plastigage. Remove all the main bearing caps and clean all the oil or assembly lube off the bearing and crank. If you put any lube on the upper bearing half, then the crank needs to come out and that needs to be cleaned off. With crank in place and dry, lay a 1 strip of plastigage on each crank journal parallel with crankshaft and slightly off center. Install all main bearing caps and torque to spec. DO NOT rotate crankshaft while plastigage is in place. Remove caps and using the paper that the plastigage was in, measure the width of the crushed plastigage strip. If within specs, you're ok....if not...find out why. Do the rod bearings the same way, 2 at a time and dont rotate crank with the plastigage in place
- Q: It's an 81 ford mustang 2.3L everytime we run it. It melts the cam bearings. HELP
- serious lack of oil flow to the cam bearings, check your oil pressure. you want a MINIMUM of 10 psi for every 1000 rpm's of engine speed. check the pickup screen on the oil pump, make sure the screen is clean, worst case, the oil passages for the camshaft are plugged up, preventing proper oil flow. also... if the bearings are not installed properly where the holes on the bearing line up with the holes in the oil passages, the cam will starve.
- 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: 2001 ford escape wheel bearings? (rear)?
- Do not buy cheap mechanical parts...you will pay dearly for those cheap parts.
- Q: Why do so many large railroads (ie,class I) flat out refuse to let rolling stock that has friction bearings, from operating or (at the very least) being moved across their system(s), even if the equipment is maintained in a better condition than roller bearing items of the same type/vintage?I appreciate all insight, -- Thanks in advance!
- They don't want to be responsible for the car if the bearings fail. Consider the cost of repairs to the right of way if they were to fail on a main line. You could pursue a damage / loss waiver clause. It sounds like you want to move a vintage rail car to another site. I envy you, I work with HO scale while you run 1:1 scale.
- Q: I usually ride bones reds in my standard skateboards but i think it is time for a change .ALSO I AM BUYING A LONGBOARD to be exact im buying a coconut cosmic secter 9 longboard so im looking for the best bearings
- bones are the bearings most wanted, but people usually go with mhs or mini logos just because of price. as long as they spin, they will work. just don't go spend $150 on some bones swiss ceramic abec9 crap that are barely better than some random $10 bearings you can get in zumiez. btw for boards look at kracked skulls. you can find many 5% off discounts on line.
