Zhejiang 6208 / HR11TN bearing little knowledge

Zhejiang 6208 / HR11TN bearing little knowledge source: bearing | last updated: - 2020 06 - 12, 6208 / zhejiang HR11TN bearing small knowledge bearing is representative of the rolling bearing. They are widely used to bear radial load and two-way axial load. They apply to high speed and low noise and low vibration required. Dust cover and rubber sealing ring sealed bearing has filled with grease in advance, outer ring with a snap ring or flange bearing is not only easy to axial positioning, and is easy to install in the shell. Bearing heavy load bearing and the size of the standard is the same, but the inner ring and outer ring is equipped with a groove, this will increase the number of balls and increase load rating. Biaxial bearing in the shaft diameter to direct contact with the bushing directly with preventing adhesion and boundary lubrication performance. Factors influencing the friction pair of friction compatibility of materials including: ( 1) Metallurgy of alloy formed as auxiliary material. （ 2) The affinity of material and lubricant. （ 3) The lubrication state of friction coefficient of secondary materials. （ 4) The material microstructure. （ 5) The thermal conductivity of the material. （ 6) The size of the material surface energy and the characteristics of the oxide film. Oil pump through the nozzle of high pressure oil injection bearing, injection of bearing oil through a bearing on the other side of the tank. When bearing at high speed, rolling element and cage also with relatively high rotation speed form the air flow around. In general it is hard to lubricant to the bearing lubrication method. At this point, you must use the high pressure injection method for lubricating oil spray into the double row bearings, the position of the nozzle should be between inner ring and maintains a center.
