SKF bearings shown in the use of its strong regularities, and repeatability is very good. Normal quality bearings (bearing) when it is used at the beginning, vibration and noise are small, but some spectrum mess, amplitude is smaller, perhaps because of some defects in the manufacturing process, such as Burr on the surface.
Movement after a period of time, to maintain a certain level of vibration and noise, spectrum very homogeneous, formed the Yi、erbei frequency only. Little formed more than three times the frequency spectrum, spherical bearings are very messy, entered a period of chaos.
FAG bearings run into use late, bearing vibration and noise starts to build, sometimes formed the abnormal noise, vibration increases more slowly, however, at this time, bearing kurtosis value Keran reaches a certain value. In our view, when the bearing is characterized by early failures.
In good condition, for as long as possible to maintain the function of bearing, maintenance, inspection, with a view to preventing accidents, it is imperative to ensure operational reliability, produced of sexual, economic progress. The measure maintains the best machinery operating premise, on schedule. Includes monitoring operation, addition or replacement of lubricants, the scheduled removal of the inspection. As a matter of running test, with spherical roller bearings of rotating tones, vibration, temperature, lubricant, and so on.
NSK bearings cleaning removed bearing tests, first documented appearance of the spherical bearings, confirm that the residual amount of lubricant, after checking the lubricant used for sampling, wash bearings. As a cleaning agent, ordinary gasoline, kerosene.
Remove bearing cleaning, heavy cleaning and light cleaning in a separate container, put metal mesh on the bottom so that bearing has no contact with the dirt container. Coarse cleaning, rotate the bearing with dirt, can damage the spherical bearings to move, should take note. Coarse cleaning oil, use a brush to remove grease, adhesive material, after a generally clean, fine wash.
Intensive wash, is in cleaning oil side the bearing rotation and careful cleaning. In addition, cleaning oils to keep clean.
