INA bearings are fine parts, so it is requested to be quite cautious when using, that is, high-performance thrust ball bearings are used, and if they are not used properly, they cannot achieve the expected performance effect, and it is easy to damage the bearing. Therefore, the use of bearings should pay attention to the following matters:
Even invisible smile dust entering the bearing can increase bearing wear, vibration and noise.
It is not allowed to press strongly, it is not allowed to strike the bearing directly with a hammer, and it is not allowed to transmit pressure through the rolling elements. I hope to open the INA bearing package again when the device is installed. When the ordinary grease is smooth, the bearing is not cleaned, and the smooth grease is directly filled. When the oil is smooth, it is not necessary to clean it normally, but for instruments or high-speed bearings, etc., clean oil should be used to remove the rust inhibitor applied to the bearing. The bearing with the rust inhibitor removed is easy to rust, so it cannot be placed arbitrarily.
First, adhere to the cleanliness of the bearing and its surrounding environment, even if the invisible smile dust enters the thrust ball bearing, it will increase the wear, vibration and noise of the bearing.
Second, when using the device, it is necessary to seriously and seriously not allow strong stamping, do not allow direct hammering of the bearing, and do not allow the pressure to be transmitted through the rolling elements.
Third, use appropriate and precise equipment tools as much as possible to use special tools, and try to prevent the use of cloth and staple fibers and other things.
Fourth, to avoid the rust of the bearing, when holding the bearing directly by hand, it is necessary to wash off the sweat on the hands and apply high-quality mineral oil before stopping the operation, and pay special attention to rust prevention in the rainy season and summer.
However, under certain special operating conditions, thrust ball bearings can achieve a life that is better than traditional calculations, especially under light loads. These special operating conditions are when the rolling surface (track and rolling part) is effectively separated by a smooth oil film and limits the appearance that may be caused by contaminants. In fact, under ideal conditions, so-called permanent bearing life is possible.
The life of an INA bearing is defined in revolutions (or hours of operation at a certain speed) that a bearing within this life shall have initial fatigue damage (spalling or defect) on any of its rings or rolling elements. However, whether in laboratory experiments or practical applications, it can be clearly seen that the appearance of the same thrust ball bearings under the same working conditions has a very different practical life. There are also several different definitions of bearing "life", one of which is the so-called "working life", which indicates that the achievable practical life of a bearing before it is damaged is caused by wear, which is usually not caused by fatigue, but by wear, corrosion, seal damage, etc.
