Bearing cleaning: often used in gasoline, kerosene as an ordinary detergent. Dismantled ntn bearing maintenance, for the first time to record the appearance of the bearings, make sure to start a wash bearing residual lubricant, lubricant sampling amount. Coarse, fine cleaning cleaning cleaning points, respectively, on the container, first put the net at the bottom of the metal, so spherical bearing no direct contact with the dirt of the container.
1, bearing vibration
Vibration bearings ntn bearing damage is very sensitive, such as spalling, indentation, rust, cracks, wear and tear and will be reflected in the bearing vibration measurement, therefore, measurable through the use of special bearing vibration measurement (frequency analyzer) the size of the vibration frequency can not infer that the unusual specific circumstances. The measured values ??due to different conditions of use spherical bearings or sensor installation location, determine the criteria for judging prior to the measured value of each machine.
2, the bearing temperature
Bearing temperature, generally have bearings outside the room temperature can be inferred, if the hole can be measured directly in the spherical bearing outer ring temperature more appropriate bit.
Typically, ntn bearing with the bearing operating temperature slowly began to rise 1-2 hours to reach steady state. The normal temperature of the bearing due to the heat capacity of the machine, heat dissipation, speed and load. Lubrication, suitable mounting part, abrupt bearing temperature will rise, there will be unusually high temperatures, then have to stop running, take the necessary precautions.
Using the thermal sensor can at any time to monitor the operating temperature of spherical bearings, and automatic alarm or stop to prevent the burning shaft accident occurred when the temperature exceeds the specified value.
: To determine the bearing to be removed can be used to check the clean-up after bearing ntn bearing maintenance and judgment.
Maintenance include: monitoring of working conditions, to supplement and replace the lubricant on a regular basis demolition inspection, it is best to maintain a regular and appropriate working conditions of the operating standard machine. Maintenance operations, a spinning sound, vibration, temperature, lubrication conditions, the spherical bearing separation-shaped bearing, you can scroll through the body, the outer ring raceway was examined.
Check the raceway, the raceway, cage wear surface state, the spherical bearing gap increases, and the unusual size did not undermine the accuracy of decline. Non-separation of the ball ntn bearings, on the one hand, the inner level of support to confirm the smooth rotating bezel.

ntn bearing repair, maintenance, to ensure operational reliability, increase productivity, the economy, in order to prevent accidents placed in the first place, to ensure the reliability of operation, increase productivity, economic, and can ensure favorable conditions for the long-term, spherical bearings to maintain the original the performance.Bearing cleaning: often used in gasoline, kerosene as an ordinary detergent. Dismantled ntn bearing maintenance, for the first time to record the appearance of the bearings, make sure to start a wash bearing residual lubricant, lubricant sampling amount. Coarse, fine cleaning cleaning cleaning points, respectively, on the container, first put the net at the bottom of the metal, so spherical bearing no direct contact with the dirt of the container.
