Bearings are precision parts, and thus require fairly cautious attitude that change is the use of high-performance bearings, if used improperly, they can not achieve the expected performance results, and easy to bearing damage when used. Therefore, the use of bearings should note the following:
I. To maintain of bearing its surrounding environment clean
Even if the the invisible smile dust entering the bearing, and also increase the bearing wear, vibration and noise.
Second, using the installation to be carefully
Not allow powerful punch, does not allow a direct hit with a hammer pressure bearing, and not allowed to pass through the rolling.
Third, the use of appropriate and accurate installation tool
To make use of a special tool, and tried to avoid using something like cloth and short fiber.
Fourth, to prevent corrosion of the bearings
The Handle directly bearing to fully wash away the sweat in hand, and coated with high quality mineral oil and then operate it rust, especially during the rainy season and summer.
However, in some special operating conditions, the bearings can get longer in the life of the conventional calculation, especially in the case of a light load. These special operating condition is that, when the rolling surface (track and the rolling member) by a lubricant film effectively separated and limit the pollutants may cause surface damage. In fact, in the ideal conditions, the so-called permanent bearing life is possible.
