At present, the economy is developing rapidly, and we all know that the use of needle roller bearings plays a very important role in our lives, and it is also an indispensable part of our lives. The equipment we use in production activities has become more and more. We all know that the equipment used in all walks of life is being updated. If you don't keep up with the market development trend, it is likely to be eliminated. So next let Xiaobian lead you to see the advantages and disadvantages of needle roller bearings. I hope it will be helpful to you. Advantages of needle roller bearings: low friction resistance, low power consumption, high mechanical efficiency, easy to start. Size standardization, interchangeability, easy installation and removal, easy maintenance. Compact structure, light weight, axial dimension is more reduced. High precision, high speed, small wear and long service life. Some bearings have the performance of automatic centering, suitable for mass production, stable and reliable quality, high production efficiency. The transmission friction torque is much lower than that of hydrodynamic bearings, so the friction temperature rise and power consumption are lower
