 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.


Product Applications:


Needle roller bearings are mainly used in car engines, transmissions, compressors, cranes, etc.

Q:Needle roller bearing is also called cam bearing?
Seems not.Cam bearings are also called roller bearings and bolt bearings.
Q:Dimensions of needle roller bearings
There isn't such a strong needle roller. But look at the picture. It's likeHave not seen in kind, in terms of size, there is a support roller meet, estimate and reference it, not necessarily accurateBrand: Germany INA NATR30 if the seal is: NATR30UUThe following diagram: small d:30 D:62 C:28 B:29Cheaper to use in Japan, IKO, model is: NART30
Q:What are the differences between cylindrical roller bearings and needle roller bearings?
What are the differences between cylindrical roller bearings and needle roller bearings? In particular, if the roller and needle diameter is about the same, cylindrical roller bearings and inner ring needle roller bearings seem to be difficult to identify it
Q:The difference between NK type and NKI type in needle roller bearings
NK and NKI are light series needle roller bearings. The difference is that one with inner ring and one without inner ring. The following problems are shown. Relevant technical data of the model are compared. Are they in line with your requirements?:INA needle roller bearing NK40/20-TVLight seriesFw 40, mmD 50, mmC 20, mmRmin 0,3 mmM 78 g qualityCr 26000 N basic rated dynamic load radialC0r 47000 N basic rated static load radialCur 6700 N fatigue limit load, radialNG 10900 1/min limit speedNB 6400 1/min reference speedINA needle roller bearing NKI35/20-TVLight seriesD 35, mmD 50, mmB 20, mmF 40, mmRmin 0,3 mmS, 0,5, mm axial displacement distanceM 122 g qualityCr 33500 N basic rated dynamic load radialC0r 56000 N basic rated static load radialCur 9800 N fatigue limit load, radialNG 11500 1/min limit speedNB 6200 1/min reference speed
Q:Roller needle roller bearings can be used directly as a wheel?
Yes, but it is not recommended.I. cost valueThe KR58 driven roller bearings are of great value. The purpose of the design is to maximize the effect with minimal cost, and the cost of the bearing is undoubtedly high. For example: ordinary 6306 bearings, a single bearing can withstand 1500 kilograms of weight, with 10 can be, the value of KR58 is much smaller.Two 、 operation flexibility and endurancePlain ball bearings are much more flexible than roller bearings. They are easy to purchase on the market, and it is easy to solve the problem of poor working conditions with bearings with sealed coversSome of the printing equipment is had to use this kind of bearing, the car to do this, put fine timber to petty use!!
Q:How much speed can the needle bearing of inner bore 17mm bear?
There are many kinds of needle roller bearings, which do you think?
Q:Which method should be used for axial fixing of needle roller bearing in stamping outer ring?
For the shaft, the bearing seat is fixed in the case, if the load direction remains unchanged, then take the shaft and cone fitting, the bearing seat and the outer loose. But the press pin of the outer ring is different. The outer ring and the bearing seat of the outer ring needle roller bearing must be tightly matched, or interference fit, because the roundness of the raceway of the outer ring can be ensured. However, another function of interference fit is to a certain degree of fixed outer ring. For needle rollers, most of them are sufficient. Do not forget the characteristics of needle roller bearings - they do not bear axial force. Then, when installing, can I use the seat block to limit the position? The answer was No. Please note the stamping of the outer ring bearing, both sides are asymmetrical. In order to fit the needle and cage, one lip of the outer ring needs annealing so it is very soft. Because it is very soft, so the installation of this side can not be pressed to the end cap or shoulder and so on. The correct installation method is the installation tool and do a simple calculation of some, there is no longer enough.
Q:Needle roller bearings are how to process the needle, so smooth finish?
The process of needle: blank forming, deburring, heat treatment, coarse and fine grinding, end rolling surface, super finishing rolling surface polishing or sawdust.For flat head or taper head needle roller, such as blank forming, it is difficult to guarantee the length and size tolerance, and the grinding double end process can be increased. If the convex generatrix rolling surface is needed, it can be carried out directly in the process of super finishing, rolling or channeling.
Q:Working principle of one-way needle roller bearings
The main structure of the unidirectional bearing EG unidirectional roller bearing EG-- | stamping outer ring needle roller clutch (one-way bearing) can be used as a converter, a non-return device, overrunning clutch. HF (needle roller clutch): composed of stamping outer ring and plastic cage. The cage can be provided with plastic spring or stainless steel leaf, guide roller, roller, roller and needle on outer ring as locking device. HFL (clutch and bearing assembly): support bearings are mounted on both sides of the needle clutch and bear radial loads. The needle bearings and plastic cage assemblies are used as supporting bearings
Q:What are the needle roller bearings with an inner diameter of 14, an outer diameter of 20 and a width of 20?
Is the needle roller and cage assembly? Or with stamping outer ring needle roller bearings?
