Rolling bearings are precision components, it used to be careful. No matter how high performance of NSK bearings, if used incorrectly, you will not get the expected performance. Caution the bearing units are as follows.
First, keep the bearings and the surrounding environment clean
Even invisible micro dust entering the NSK bearings, also increase the bearing wear, vibration and noise. NSK bearings as well as its surrounding annexes should be kept clean, particularly the dust and dirt, tools and working environment must be kept clean.
B, used when installing to carefully
Powerful punching is not allowed, not allowed with a hammer, percussion bearing directly, by passing rolling pressure is not allowed.
Third, the use of appropriate and accurate installation tools
Using special tools as much as possible, avoid using things like cloth and fiber.
Four, the prevention of bearing corrosion
Direct hand when taking bearings, to wash away the sweat in the hands of fully, and coated with high quality mineral oil before action, paying particular attention to rust in the rainy season and summer. However, in a special operation conditions, NSK bearings can be obtained relatively longer than the traditional calculation of life, especially under light load conditions. These special conditions are, when the scroll surface (rail and scroll) are separated by a lubricant film effectively and limit the pollutants may cause surface damage. In fact, under ideal conditions, the so-called permanent bearing life is possible.
NSK bearings to move, take the outer ring of the inner ring raceway surface, because taking the rolling is rolling contact, so running track for the dark side, running track is not on the Raceway surface tends to be, this change can be seen load assumption, so being removed bearing environments, bearing seal what type?. Please pay strict attention and look at the Raceway surface running track. If a careful look at the running track, you will learn that only take radial loads, bear large axial loads, moments of endurance load, or unequal is no extreme rigidity on bearing boxes.
Enable the confiscation of the NSK bearing can be combined with the ominous can load and remove errors, and so on, and becomes the escape check clue to cause of bearing damage done.
If no free selection error and perhaps the exact use, prior to bearing life, but for a long time, is that such an environment, damaging form of split. The other hand, tooling design and realization of management system of the bearing. Also later raised no unexpected damage, and stand up to use advanced damage, as the damage reasons of late, considering non-use and lubrication is insufficient, in turn without intrusion, NSK bearings remove errors and deflections of the shafts, shaft and housing research, such as inadequate.
