Q:Working principle of one-way needle roller bearings
One way bearing is a type of bearing that can only be turned in one direction and locked in another direction.The metal shell of the one-way bearing, contains a lot of rollers (or needle ball), and the rolling block (acupoints) shape so that it can only roll in one direction, (because the installation direction of the rolling direction opposite spring, so spring is compressed). In another direction when the rolling direction and spring mounting same direction, not to cause the compression spring, up roller, roller to produce a lot of resistance in between the inner shell and outer shell (the so-called "one-way"), stop rolling bearing.
Q:How much speed can the needle bearing of inner bore 17mm bear?
This depends on the lubrication, lubricating oil viscosity, pressure is different, allowing the speed is also different
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: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: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: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:Roller needle roller bearings can be used directly as a wheel?
Under better working conditions, it can be used as a wheel. There may be problems in using the wheel as a poor condition;Bad conditions are high speed (high temperature), high load (no wheel is not related), rigid contact (accelerated external hub wear), high frequency vibration caused by uneven contact surface, high temperature environment.In general, the use of wheels can lead to higher speed and faster wear.
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?
General stamping ring needle roller bearings are the outer diameter and the hole is fit to the location, so for stamping ring bearings have a pressing force of the technical requirements. Here I put it in the production process: stamping, heat treatment (about carburizing layer to control, otherwise the last edge will open - Cases) left - lips - cast oxide annealing oxidation layer, the holder on the needle sleeve ring, stamping edge (technical requirements: the rolling head edge within the height, diameter, (note that both ends and in the middle to be consistent) and pressed into the ring after the gage qualified).
Q:Many one-way needle roller bearings have small holes in the inner and outer rings. What's the function of these small holes?
The basic structure and NU type cylindrical roller bearing inner ring bearing the same, but because of the needle, the volume can be reduced, and can bear large radial load to the bearing without inner ring shaft mounting surface with suitable precision and hardness as the raceway surface
