What is tolerance of bearing: nj314 bearing bearing

Rubber seal bearing dustproof and sealing how said: dustproof expressed in Z, sealing with S ( Felt ring seal with FS said; LS in rubber seal) 。 Bearing temperature rise shall not exceed the ambient temperature shall not exceed ℃ JB/T - high temperature , single row bearing sin - Methyl amino acetonitrile glerowbearin - Methyl amino acetonitrile g has a column of rolling element bearing. Metal substrate in the process of friction for the most part bear the load, the development of high temperature and overloading, complex conditions, such as low speed, including lining and corrosive self-lubricating bearing materials is a priority. Moving cone is an important part in cone crusher, need to match the assembling bolt, spherical bearing, and coordinates with the upper and lower bushings, hard to avoid in the production will be affected by wear and tear, this article mainly introduces the dynamic cone cone break the cause of the damage, and how to reduce the wear to prolong the service life of moving cone. % ~, it should be pointed out, has the fine carbide dispersion distribution of the original tissue, quenching heat insulation, not dissolve tiny carbides would gather to grow up, make its coarsening. Sieve plate thin frame fracture there are likely to be thin, sieve plate, the better way to solve this problem is more appropriate side panel, or the vibrator side panel near the local increase of plate to enhance the whole screen body rigidity, it is not easy to tremble and fracture screen box. & emsp; & emsp; Was looking at these too professional, but we just have to deal with their products, that is electrical insulation bearing. Which shows that the evaluation of bearing over-current risk grade of a reliable principle is calculated through the current density of bearings, in other words, the effective amps were divided by the rolling element and the inner ring and outer ring raceway contact area. The formation of lubrication film is the basic condition of sliding bearing can work normally, factors affecting the formation of lubrication film lubrication way; Relative speed of motion pair; The physical properties of lubricant and the roughness of the surface, etc. Mounted on the shaft bearing cleaning, relied on pour oil or oil injection method, wash oil with kerosene after first use gasoline; Difficult to clean off the oil, use first - ℃ hot oil leaching or oil injection, and then clean with gasoline. When the oil level in oil the scribed line, the actual measurement, bearing the low row ball has just come into contact with the oil level, only when the oil level is shown in the calibration on line, to meet the needs of the operation. Cylindrical roller bearing inner ring remove can take advantage of the induction heating method, device is inappropriate: cut too early about % off effect of the bearing is disapproved by the device and realize the accurate device has provoked.
