1. INA bearings are precision parts, so they require a very cautious attitude when using them, that is, high-performance imported bearings and thrust ball bearings are used. Bearing damage.

Therefore, the use of imported bearings should pay attention to the following matters:

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

3. Imported bearings are not allowed to be punched strongly, not allowed to hit the bearing directly with a hammer, and not allowed to transmit pressure through the rolling elements.

4. It is hoped that the INA bearing package should be opened during installation. In general grease lubrication, the bearings are not cleaned, and grease is directly filled. When oil is lubricated, it is generally not necessary to clean it. However, for instruments or high-speed bearings, clean oil should be used to remove the rust inhibitor coated on the bearings. Bearings with rust inhibitor removed are easy to rust, so they cannot be placed arbitrarily.

5. Keep the imported bearing and its surrounding environment clean Even if the smiling dust invisible to the naked eye enters the plane thrust ball bearing, it will increase the wear, vibration and noise of the imported bearing.

6. Be careful when using and installing. Do not allow strong stamping, directly hit the imported bearing with a hammer, and do not allow pressure to be transmitted through the rolling elements.

7. Use suitable and accurate installation tools, try to use special tools, and try to avoid the use of cloth and short fibers.

8. Prevent the rust of the needle roller bearing. When taking the needle roller bearing directly by hand, it is necessary to fully wash off the sweat on the hands, and apply high-quality mineral oil before operating. In the rainy season and summer, special attention should be paid to rust prevention.

9. However, under certain special operating conditions, the life of INA imported bearings and thrust ball bearings can be longer than that of 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.

10. The life of an INA bearing is defined by the number of revolutions (or the number of hours of work at a certain speed): the bearing within this life should have initial fatigue damage (spalling or defect) on any bearing ring or rolling element. . However, whether in laboratory tests or in actual use, it can be clearly seen that the actual life of thrust ball bearings with the same appearance under the same working conditions is very different.

11. In addition, there are several different definitions of bearing "life", one of which is the so-called "working life", which means that the actual life that a bearing can achieve before damage is caused by wear, damage is usually not caused by fatigue, Instead, it is caused by wear, corrosion, seal damage, etc.
