Needle roller bearing source: what are the advantages and disadvantages of this website the author: the administrator to release time: 2017 - 12 - 28 13:48:23 views: 0 needle roller bearing, what are the advantages and disadvantages of the current rapid economic development, the use of needle roller bearing is known to all play an important role in our life, is an indispensable part of our life. We used in production activities to the equipment becomes more and more, we all know that the equipment used in all walks of life are updated, if you don't keep up with market trends, probably will be eliminated. So then let authors led together and see what are the advantages and disadvantages of needle roller bearing, hope to be of help. Needle roller bearing: the advantages of small frictional resistance, small power consumption, high mechanical efficiency, easy to start. Size standardized and interchangeable, installation convenient disassembly, convenient maintenance. Compact structure, light weight, the axial size is more narrow. High precision, high speed, wear small, long service life. Part with automatic bearing performance, suitable for mass production, quality stable and reliable, high production efficiency. Transmission was much lower than the fluid dynamic bearing friction torque, so the friction temperature rise and low power consumption; Starting friction torque is only slightly higher than the rotating friction torque; Bearing the sensitivity of deformation to load change is less than the fluid dynamic bearing; Only need a small amount of lubricant can run normally, the runtime can provide lubricant for a long time; The axial size is smaller than traditional fluid dynamic bearing; Can bear radial and thrust load at the same time; In the large load - Speed range, the unique design can obtain excellent performance; Performance of the bearing load, speed and speed fluctuations relatively insensitive. Needle roller bearing faults: a big noise, and the structure of the bearing is more complex, high cost, and even good lubrication of the bearing installed correctly, dustproof moistureproof, operating normally, they will also because of the surface of the rolling contact fatigue failure. About the advantages and disadvantages of needle bearing we went first to speak to this, I believe you can look after a good understanding of needle roller bearing, they occupies a very important role in our life, so if you want to good use of it, is designated to select normal needle bearing factory, welcome to our consultation understand jiaxing needle bearing co. , LTD.
