- Q:Cylindrical roller bearings and needle roller bearings is the same thing?
- It's certainly not the same thing. Look at the mechanical manual. Top of it. See what you've got
- Q:What are the differences between cylindrical roller bearings and needle roller bearings?
- Back to the 2# plane thrust roller, there are also, such as K811, K812, K893, K894. The first two are single row roller, K893 and K894 are double row roller, these are thrust bearings, INA code name, you can scroll down the directory
- 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: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?
- With the same diameter, the needle roller bearings have smaller radial sizes and smaller carrying capacity.
- 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 is the bearing capacity of needle bearing and copper sleeve?
- The copper sleeve and the shaft are surface contact, and the bearing capacity is large;The needle roller of needle roller bearing is several line contact, and it has less bearing capacity than copper sleeve;The sliding friction, friction force is large, suitable for low speed and heavy load, preferably with good lubrication, in static pressure under the condition of high speed, such as grinding machine is of high speed and heavy load static and vibration resistance than good bearing;The latter is rolling friction, and the transmission efficiency is higher, suitable for medium speed.
- 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: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.
