1.The drawn cup needle roller bearings are needle roller bearings with the deep drawn, thin-walled outer ring with either an open end or closed end.

2. The bearings are characterized by a very low sectional height and high load carrying capacity

3. The bearings are typically used in applications where the housing bore can not be used as a raceway for a needle roller and cage assembly but where a very compact and ecnomical bearing arrangement is required.

4. Typically, drawn cup needle roller bearings have a single row of rollers. However, wide sizes incorporate two needle roller and cage assemblies immediately asjacent to each other with a lubrication hole in the outer ring.


Product Applications: 


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

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 is the needle roller bearing model with outer diameter 21 and inner diameter 16?
The needle roller bearing model with an outer diameter of 21 and an inner diameter of 16 does not exist.The needle bearing type with an outer diameter of 21 and an inner diameter of 15 is BK1512 or BK1516.The needle bearing type with an outer diameter of 22 and an inner diameter of 16 is BK1612 or BK1616.
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: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?
Q:Needle roller bearing is also called cam bearing?
According to the ball bearings, there are ball bearings, cylindrical roller bearings, tapered roller bearings, needle roller bearings belong to cylindrical roller bearingsIt seems that the cam bearings have not been heard
Q:What are the differences between needle roller bearings and cylindrical roller bearings?
With the same diameter, the needle roller bearings have smaller radial sizes and smaller carrying capacity.
Q:Cylindrical roller bearings and needle roller bearings is the same thing?
Cylindrical roller bearings, rolling bodies are cylindrical roller bearings. Cylindrical roller and raceway are line contact bearings. Load capacity, mainly bear radial load. The friction between the rolling body and the ring block is small and suitable for high speed rotation. According to the ring has no edge, can be divided into NU, NJ, NUP, N, NF and other single row bearings, and NNU, NN and other double row bearings. Needle roller bearings are cylindrical roller bearings, relative to their diameter, the roller is thin and long. This roller is called needle roller. Although it has a small section, the load bearing capacity of the bearing is still high, with thin and long needle bearing roller (roller diameter of D = 5mm, L/D = 2.5, L roller length), so the radial structure is compact, the minimum diameter of the diameter and load capacity and other types of bearings, bearing the same, especially for the structure in radial installation size limited. According to the use of different occasions, can choose the inner ring of the bearing or needle roller and cage assembly, the shaft neck surface and the surface of shell holes matched with a bearing directly as the bearing inner and outer rolling surface, in order to ensure the load capacity and operating performance and have the same ring bearing, shaft or housing bore raceway surface hardness the machining precision and the surface quality of bearing ring raceway and similar. This kind of bearing can only bear radial load.
Q:The difference between NK type and NKI type in needle roller bearings
Hello, I am a professional sales of bearings, NK40/20 bearings with inner ring called NKI35/20, NKI35/20 went to the inner ring is NK40/20. in the industry just code in different ways, the other the same, the difference is an inner ring with a ring. A thing, of course can be generic, the quality difference is negotiable. As you mentioned inside the needle is not the same, that is for sure, because the internal structure of each of the manufacturers are not the same, sometimes the size of the needles of different lengths is very normal, especially domestic generally not unified. If this bearing higher requirements with the best inlet of the "INA" or "IKO" two brands of domestic use. "FYB" is a German.INA company, now belong to the Schaeffler Group.IKO is Japan's Tom Xun.FYB Corporation is domestic Zhenjiang Feiya bearing company.INA is the ancestor of the needle bearing company, IKO is then introduced INA technology and products Do the products with the INA series, the material will be worse, the accuracy of FYB is similar to the imported INA production line, the needle roller bearing is currently doing the best, although the price is cheaper than Japan, but the quality is not to say, to be roughly the same small Japan.
Q:Many one-way needle roller bearings have small holes in the inner and outer rings. What's the function of these small holes?
It should be the oil storage hole, whose main function is to store grease and lubricate the needle roller.
Q:Dimensions of needle roller bearings
Needle roller bearings are cylindrical roller bearings, the roller is slender, the cross-section is smaller, and the bearing capacity of the load is higher, so it is suitable for radial installation size limited supporting effect. Needle roller bearings are equipped with a thin and long roller (roller length is 3~10 times the diameter, generally less than 5mm diameter), radial structure is compact.A complete bearing code is composed of the basic code number plus one or more supplementary codes. All standard bearing SKF have certain basic types, there are usually three, four or five numbers, or letters and numbers, the first number or the first letters said bearing type, followed by two digits identifies the size of ISO series.Because the model of needle roller bearings is relatively complex, only a few specific classification and model control of needle roller bearings are introduced here:1, centripetal needle roller and cage assembly (type K)2, outer ring with double lock ring needle roller bearings (NA, NKI, RNA, NK)3. Single row needle roller bearings with double retaining rings (NA, NKI, RNA, NK)4. Double row needle roller bearings with double retaining rings (NA, RNA)5, stamping outer ring needle roller bearings (HK type, BK type)The bearing has low cost and large carrying capacity, and is suitable for the supporting structure with limited size of installation.
