INA needle bearing preload of the cause of the damage

INA bearings belong to precision parts, so when use requires a fairly cautious attitude, even if the use of high performance bearing, if use undeserved, also cannot achieve the expected performance effect, and easy to make the bearing damage. With modern rolling bearing structure of China's most ancient rudiment of bearing but now the real meaning from the start, attaches great importance to product quality, technology development and market development as a result, examine the needle roller bearing damage, can be found in most cases it may be the result, generally speaking, a third of the INA bearing damage resulting from the fatigue damage, a third of the other resulting from poor lubrication, a third of the other resulting from pollutants into the bearing improper handling or installation. Use special tools as far as possible, avoid using cloth class and short fiber, things like that. Dust into the bearing even invisible to the naked eye smile, also can increase the bearing wear, vibration and noise. Directly with the hand take bearing, want to wash hands fully the sweat, and again after coated with high quality mineral oils, especially in the rainy season and summer to pay attention to rust. 1. Keep the INA bearings and the surrounding environment clean even tiny dust into the bearing of invisible to the naked eye, also will increase the wear of bearings, vibration and noise. In fact, under ideal conditions, the so-called permanent bearing life is possible. 2. Use when installation should careful not allowed powerful punch, are not allowed to use hammer percussion bearing directly, not allowed by transfer roller pressure. 3. 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. INA bearings but now the real meaning in any test in the laboratory or in actual use, can be clearly seen, under the same working conditions for the appearance of the same needle roller bearing, real life was very different.
