The use of high temperature often means that the full complement cylindrical roller bearing has been in an abnormal condition. High temperatures are also detrimental to bearing lubricants. Occasional bearing overheating can be attributed to the lubricant of the bearing. If the bearing is continuously rotated at a temperature exceeding 125°C, the bearing life will be reduced. The reasons for causing high temperature bearings include: insufficient lubrication or excessive lubrication, impurities in the bearing raceway, high limit speed, and permanent overload operation of the bearing. In normal applications, the touch is sensitive to bearing damage, and spalling, indentation, rust, cracks, wear, etc. will all be reflected in the bearing vibration measurement. Therefore, by using an additional bearing vibration measurer (frequency analyzer, etc.), the magnitude of the vibration can be measured, and the very specific situation can be inferred through the frequency distribution. The measured values ​​vary due to the application conditions of the bearing or the placement of the sensor, so it is necessary to analyze and compare the measured values ​​of each machine in advance to determine the calibration specification. The selection of full complement cylindrical roller bearings is quick and easy to provide, and the resultant radial load on the fixed load load is exposed from the local ring raceway fixed ring and transmitted to the corresponding shaft or bearing local. The characteristic of this load is that the radial load vector is a relatively static composite and ring. Bearing the load ring can be applied relatively loosely. The torsional load is the resultant radial load of the full complement cylindrical roller bearing ring on the roller that is twisted in the circumferential direction, and each side of the rotation, such as the torsion load, is caused by the resultant vector phase ring radial load torsion, the load . The torsional load ring is carefully combined, and in exceptional cases, the load, if selected, is light or heavy, the load at low speed is only unintentional, the bearing uses hard materials and the surface roughness is high, and the torsional load is subjected to the ring Can also be used looser. The third load swinging load or non-biased load, the combined deflection of the radial load of the load ring is uncertain, the characteristic of the bearing in the full complement cylindrical roller bearing manufacturer is that the radial load vector of the synthetic ring is the advantage of the ring raceway, in the inevitable The impact load, vibration, and load in the area are inclined to swing, and the rollers have to bear a certain area, or preferably the load of the bearing, and the load value changes from time to time. To bear the load-bearing swing, the outer ring and circumference, the bearing, and the hole should be used carefully. 1. The roller and the raceway are in line contact or trimmed line contact, and the radial bearing capacity is large, which is suitable for heavy loads and impact loads. 2. The conflict coefficient is small, suitable for high speed, and the limit speed is close to the deep groove ball bearing. 3. N type and NU type can be moved axially, which can adapt to the change of the relative position of the shaft and the shell caused by thermal expansion or installation error, and can be used as free end support. 4. The processing requirements for the shaft or seat hole are high. After the bearing is placed, the relative deflection of the outer ring axis should be strictly controlled to avoid intensive contact stress. 5. The inner or outer ring can be separated for easy placement and destruction.
