What are the reasons for linear bearing damage? (1)

Bearings are precision parts, so they require considerable caution when using them, that is, high-performance bearings are used. If they are used improperly, the expected performance will not be achieved, and the bearings are likely to be damaged. Therefore, pay attention to the following matters when using bearings:

1. Keep the bearing and its surrounding environment clean

   Even if tiny dust invisible to the naked eye enters the bearing, it will increase bearing wear, vibration and noise.


2. Be careful when using and installing

   Strong punching is not allowed, hammers are not allowed to directly strike the bearing, and pressure is not allowed to pass through the rolling elements.


3. Use appropriate and accurate installation tools

   Try to use special tools and try to avoid using cloth and short fibers.


Fourth, prevent the corrosion of the bearing

   When picking up the bearing directly by hand, wash away the sweat from your hands and apply high-quality mineral oil before proceeding. Pay special attention to rust prevention during the rainy season and summer.

   However, under certain special operating conditions, the bearing can obtain a longer life than traditional calculations, especially under light load conditions. These special operating conditions are when the rolling surfaces (tracks and rolling elements) are effectively separated by a lubricating oil film and limit contaminants that may cause surface damage. In fact, under ideal conditions, the so-called permanent bearing life is possible.
