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:How much speed can the needle bearing of inner bore 17mm bear?
The needle bearings with an inner diameter of 17mm have various forms.1. needle roller and cage assembly2. press outer ring needle roller bearing3. solid needle roller bearingsPermissible rotation speed of needle and cage assemblies:Grease lubrication: 16000rpmOil lubrication: 26000rpmAllowable speed of needle roller bearing for stamping outer ring:Grease lubrication: 12000rpmOil lubrication: 19000rpmAllowable rotational speed of solid needle roller bearings:Grease lubrication: 13000rpmOil lubrication: 20000rpm
Q:What is the bearing capacity of needle bearing and copper sleeve?
The bearing capacity of plain bearings with copper sleeve is large. However, the speed of the shaft has a certain requirement, the speed is too low, too high, can not establish oil film, will soon wear.
Q:Needle roller bearing model NK what does it mean?
Outer ring double block (or double lock ring) with cage, needle roller bearings NA, NKI, NA and NKI bearings without inner ring, that is, RNA, NK needle roller bearings
Q:What is the needle roller bearing model with outer diameter 21 and inner diameter 16?
The outer diameter of 21 needle bearings with 16, the market is not available.The outer diameter of 21 needle roller bearings through 15, some models are hk1512.
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.Needle roller bearing (needlebearing) is a roller bearing with cylindrical roller, relative to its 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 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. The needle roller bearing for stamping outer ring is needle roller bearing with thin stamping forming outer ring.
Q:What are the needle roller bearings with an inner diameter of 14, an outer diameter of 20 and a width of 20?
Only know the inside diameter, the outside diameter and the height. There are many kinds of needle roller bearings!!
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: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: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
