Precautions for the use of bearings

Rolling bearings are precision components, and their use must be carried out with corresponding care. No matter how high performance bearings are used, if they are not used properly, the expected high performance will not be obtained. Notes on the use of bearings are as follows.

1、Keep the bearing and its surrounding environment clean

Even if the tiny dust invisible to the naked eye enters the bearing, it will increase the wear, vibration and noise of the bearing. Bearings and their surrounding accessories should be kept clean, especially dust and dirt, and tools and working environment must also be kept clean.

2、Use the installation carefully

Do not allow strong stamping, direct hammering on the bearing, or pressure transmission through the rolling body.

3、Use suitable and accurate installation tools

Try to use special tools, strongly avoid the use of cloth and short fiber and other things.

4、Prevent the bearing from rusting

When picking up the bearings directly by hand, fully wash away the sweat on your hands and apply high quality mineral oil before operation, and pay particular attention to rust prevention in the rainy season and summer. However, under certain special operating conditions, bearings can obtain a longer life than conventionally calculated, especially under light loads. These special operating conditions are when the rolling surfaces (tracks and rolling elements) are effectively separated by a lubricant film and the possible surface damage caused by contaminants is limited. In fact, under ideal conditions, so-called permanent bearing life is possible.
