Using NTN Bearing process due to improper operation, insufficient lubrication, rust and corrosion, and other factors such as current, exterior materials, causing eccentricity NTN greatly reduced bearing life. Therefore it is necessary in the course of using the NTN Bearing NTN Bearing precautions have sufficient knowledge and understanding.
     A. Bearing lubrication is not sufficient:
         NTN inadequate or improper lubrication oil may cause abrasions or serious element bearing deformation
         Preventive measures: improved lubrication system, timed appropriately supplement or replace the lubricant
     B. Bearing operation is not standardized:
         Bearing improper installation, operation, or disassembly may cause deformation or defect of cage
         Precautions: Use proper handling, installation and removal tools, and the use of authentic Beijing Federer America NTN bearings.
     C. Bearing rust and corrosion:
         Contact with water may cause pitting and rusting bearing elements. Bearing rust after injury at work may lead to spalling
         Precautions: Periodically check the seals to ensure a good seal, proper storage NTN Bearing
     D. Bearing currents:
         When rotation of the bearing grooves or power may cause nicks. When the bearing is stationary, electrically operated Improper grounding can cause minor burns
     Precautions: Before NTN Bearing components other than the solder connections to reduce or avoid the current through the bearing through proper grounding
     E. Bearing External material:
         Abrasive particle contamination and debris intrusion may cause NTN Bearing face wear, abrasions and depression
         Precautions: Clear invasive particles and debris, replace the lubricant, check the sealing system
     F. Bearing Eccentric:
         Eccentric, tilted or excessive load may cause geometric stress concentration or flaking
         Precautions: Use precise machining NTN bearing and retaining shoulder
You can always use heat sensors to monitor bearing temperature, and automatic alarm or stop to prevent burning shaft accident temperature exceeds a predetermined value. Often expressed by high-temperature bearings in unusual circumstances. High temperature is also harmful to the bearing lubricant. Sometimes overheated bearing can be attributed to the bearing lubricant. If the bearing temperature over 125 ℃ even move to reduce long bearing life. Causes high temperature bearings include: lack of lubrication or excessive lubrication, lubricant. Contains impurities, the load is too large, the bearing ring damage, lack of space, and high-friction seals and so on.
Therefore, continuous monitoring of the temperature of the bearing is necessary, NTN Bearing Bearing measurements either by itself or other important parts. If you are under the same operating conditions, any change in temperature may indicate a fault has occurred. Regular amount bearing temperature can be measured by means of a thermometer, such as digital thermometers, bearing temperature can be accurately measured and determined in accordance ℃ or Fahrenheit units.
    Bearing temperature, generally bearing chamber outside temperature can be inferred that if the use of the hole can directly measure the temperature of the bearing outer ring, NTN Bearing is more appropriate. Typically, bearing with the bearing operating temperature slowly began to rise 1-2 hours after reaching steady state. Normal temperature of the heat capacity of the bearing, heat capacity, speed and load of the machine to another. If lubrication, install the appropriate department, the bearing temperature will be rapid rise, there will be abnormally high, then you must stop running, take the necessary precautions.
