IKO roller bearing quality problem of using operation

IKO bearing raceway and roller contact surface appear uneven pits, states that cause plastic deformation of the roller bearing is bearing in large under static load or shock loading, working on the surface of the local stress exceed the material yield limit, this kind of situation usually happened in the low-speed rotation of the bearing. Rolling bearing is precision components, and its use should be measured accordingly. No matter how high performance using IKO bearings, if use undeserved, will not get the desired performance. About the use of the roller bearing matters needing attention are as follows. One, keep the bearing 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. Bearings and its surrounding accessories should be kept clean, especially the dust and dirt, tools and working environment must be clean. Second, use the installation should be careful when not allowed powerful punch, are not allowed to use hammer, tap on a roller 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 take IKO bearings, with the hand 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. However, in some special operating conditions, roller 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. The causes of high temperature IKO bearings include: insufficient lubrication or excessive lubrication, lubricants containing magazine, the load is too large, roller bearing damage, clearance, and the oil seal of high temperature and friction and so on. Bearing roller and the inner and outer ring raceway surface under the role of the periodic pulse load, resulting in a periodic change of contact stress when stress cycles after reaching a certain value, the rolling element bearings, their work within or on the surface will produce fatigue spalling if the bearing load is too big, can make the fatigue is increasing also, bearing installation is not straight, shaft bending, also can produce raceway flaking off IKO bearing raceway fatigue spalling can reduce the running accuracy of shaft vibration and noise in the organization. Burns of the roller bearing on the raceway and rolling body heat tint burn is usually the cause of insufficient lubrication, lubricating oil quality does not conform to the requirements or deterioration, and IKO bearing assembly too tight.
