Running the importance of linear motion bearings in the maintenance of life

Linear motion bearings if get good lubrication, and cut off the right moisture and debris, said oil seal should not wear. However, best when open the bearing box, check the bearing and periodically check the oil seal. Check of the condition of the near the bearing oil seal, in order to ensure that they are enough to prevent hot liquid along the axis of infiltration or corrosive liquid or gas bearing, oil seal if already wear should be replaced as soon as possible. High temperature often said bearing is in abnormal situation. High temperature also harmful to within the bearing lubricant. Sometimes bearing overheating can be attributed to bearing lubricant. If the linear motion bearings in more than 125 degrees Celsius temperature operation for a long time, will reduce the bearing life. The causes of high temperature bearing include: insufficient lubrication or excessive lubrication, lubricants containing magazine, heavy load, bearing damage, clearance, and the oil seal of high temperature and friction and so on. Check the status of the operation of the machine, monitoring, lest cause the equipment downtime. A, bearing selection stage, need to consider many factors, Example: load, hardness, running environment, etc. ) First of all, a good linear motion bearings design will make bearing reaches its maximum life span of the two, correct storage, linear motion bearings before installing the best shall be kept in their original packaging. Need to stay clean, no moisture, relatively constant temperature environment. Shaking and vibration may be forever on the mechanical properties of the damaged bearing, therefore in the process of processing and storage should avoid vibration. General bearing should be kept level, some of the heavier bearing long upright, will be deformation due to its own weight! Also, coated with grease, Or sealed) Linear motion bearings need to be careful, because the grease will change after long time storage density. When the bearing is used for the first time, there will be a certain degree of rotation noise. So, this kind of bearing on time should be to control according to the principle of first in first out! Three, clean, it is very important to bearing. The rotation of the linear motion bearing ring surface is very smooth, is sensitive to damage caused by pollutants. Impurity particles are influenced by the excessive rolling rolling element and partial pressure in the bearing, eventually lead to permanent material fatigue. Four, comprehensive equipment installation again, linear motion bearings should use the right tools carefully install and remove. Should choose the right tools! Industry experts estimate that premature bearing failure, 16% were caused by incorrect installation. Generally a large number of installation, generally take appropriate bearing installation of equipment.
