A deep groove ball bearing is a kind of precision machine part that can be purchased everywhere, but no matter how high-performance and good brand bearings are if they are not used properly, they will not have the expected effect or even shorten the bearing life:
1. Ensure the cleanliness of the individual bearing and the surrounding environment
Even tiny dust invisible to the naked eye entering the bearing will increase bearing wear, vibration, and noise. Bearings and their surrounding accessories should be kept clean, especially dust and dirt, and tools and the working environment must also be kept clean.
2. To install the bearing correctly
Strong punching is not allowed, the bearing is not allowed to be hit directly with a hammer, and pressure is not allowed to be transmitted through the rolling elements.
3. Use appropriate and accurate installation tools
Use special tools whenever possible, and try to avoid things like cloth and short fibers.
4. Prevent bearing corrosion
When taking the bearing directly by hand, fully wash off the sweat on your hands, and apply high-quality mineral oil before operating, especially in the rainy season and summer, pay special attention to rust prevention.
However, under certain special operating conditions, stainless steel needle roller bearings can achieve a longer life than traditional calculations, especially under light loads. These special operating conditions are when the rolling surfaces (tracks and rolling elements) are effectively separated by a lubricating film and limit contamination that may cause surface damage. In fact, under ideal conditions, so-called permanent bearing life is possible.
