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
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.
Q:Roller needle roller bearings can be used directly as a wheel?
Yes, it's the roller itself. However, as the use of wheels is not so good control, because the surface of the bearing itself after finishing processing, very smooth, friction will be very small.
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:Which method should be used for axial fixing of needle roller bearing in stamping outer ring?
One end of the needle roller bearing in the stamping outer ring can take the bearing end cover and fix the outer ring in axial direction. How can the other end be fixed?
Q:What are the differences between needle roller bearings and cylindrical roller bearings?
Mainly the difference between rolling bodiesThe needle length and diameter ratio (aspect ratio) is greater than 3, less than 5 mm in diameterThe cylindrical length and diameter ratio (aspect ratio) is less than 3, greater than 5 mm in diameter
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:Needle roller bearing model NK what does it mean?
Light series needle roller bearing without inner ring
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: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!!
