The influencing factors of bearing damage

Bearing belongs to the precision parts, so when use requires a fairly cautious attitude, so is the use of the high performance bearing, if use undeserved, also cannot achieve the expected performance effect, and easy to make the bearing damage. So, the use of the bearing should be paid attention to the following: a, keep the bearing and the surrounding environment clean dust into the bearing even invisible to the naked eye smile, also can increase the bearing wear, vibration and noise. Second, use the installation should be careful when not allowed powerful punch, are not allowed to use hammer percussion bearing directly, don't allow through the transfer roller pressure. Three, using appropriate and accurate installation tools use a special tool, as far as possible to avoid use cloth class and short fiber, things like that. Four, to prevent rusting of the bearings directly with the hand take bearing, to fully wash hands sweat, and again after coated with high quality mineral oils, especially in the rainy season and summer to pay attention to rust. However, in some special operating conditions, bearing can get more than the life of the traditional computing, especially in the case of light load. These special operating conditions is, when the rolling surface ( Track and rolling piece) Can be separated by a lubricating oil film effectively and the surface of the limit of pollutants may cause damage. In fact, under ideal conditions, the so-called permanent bearing life is possible. Five, the bearing life so when calculating the bearing size, the word 'life' must have a more clear definition. Generally provided all the information about the basic dynamic load rating, which is based on a large enough number of identical bearing on the surface, can reach more than 90% of life as the basis. Different definitions of bearing life. One of them is 'working life,' said bearing under the condition of actual work, life actually reached before failure. Must pay attention to, the life of the individual bearing only through statistical method to forecast. Life calculation is just for the reliability of the bearing group and a certain program, about 90%. There was a fault in the actual use is usually not caused by fatigue, more is caused by pollution, corrosion, wear, right, or cage, lubricants or seal failure. Another 'life' is the life 'the agreement' shall be formulated by the lawsuit party departments or institutions designated industry standards, and based on some assumed load and speed for the working conditions. This is basically all the basic rating life of bearing, are generally according to the experience of similar application.
