NSK bearings under the correct use, you can have a long life. If early injuries, most likely due to selection errors caused by improper use or poor lubrication.
Therefore, during the installation of NSK bearings, we need to record the machine type, install the part, using the conditions and tie around. Through research summarize the type of bearing damage, use environment when a problem occurs in order to avoid the recurrence of a similar situation.
Accurately control the concentration of cutting fluid, when machine downtime, and rinse machine with cutting fluid surface, but also to open the machine cover, to disperse the machine working area of moist air. To prevent corrosion, a waterproof layer of grease on the metal surface. And should enable the machine strictly grounded alone is not enough to ground the electrical cabinet, in order to avoid breeding and propagation of bacteria, you should regularly clean or replace the cutting fluid, clear cutting in a timely manner, and use soft water (pure water with low mineral content) cutting concentrated liquid dilution.
NSK bearings other than quality, is a very precise parts, is both a high-performance bearings, if used in the course of improperly, not only fall short of expected performance, and it is easy to make the NSK bearing damage, in terms of lubrication must have attention.
, Be careful when using installation does not allow strong punch, does not allow for vertical direct percussion NSK bearings, passed through the rolling pressure is not allowed.
Second, the use of appropriate and accurate installation tool using the special tool, avoid using things like cloth and fiber.
Three, as far as possible keep the bearings and the surrounding environment clean even when invisible smile dust entering the NSK bearings, also increase the bearing wear, vibration and noise.
Four, the prevention of corrosion of NSK bearings by hand when taking bearings directly, to fully wash hands of the liquid, and coated with high quality mineral oil before action, paying particular attention to rust in the rainy season and summer. In a special operating 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.
