NTN bearing lubrication is best in the plan during the stop equipment, and regularly for supplement, at the same time, the old oil remove or through oil free relief will be old oil out. Add the fresh oil in before will note nozzle should be wiped clean. If thrust ball bearings bearing box no note nozzle, should be open bearing box or cover, to take out the old oil, to clean up after the same type of fresh oil added.

In order to guarantee the normal operation of NTN bearing, we need to periodically to check the oil and oil level of the oily, usually, normal oil level should be a window or mark oil equipment of a third-two-thirds range. Oil compensating for the way oil cup, the display of oil to represent only a fill oil ability, and bearing a box of oil is to satisfy the requirements of the operation, a less than its Chinese oil cup a quarter of the total volume can consider to fill oil.

1, low temperature high-speed bearing grease

At present, the use of thrust ball bearings equipment is fine, prompting bearing grease used must have the following properties:

(1) has the same operation and bearing life, try to prolong maintenance cycle, shorten the down time, improve the productivity of Labour.

(2) the dn > 5 x 105 of the high speed to ensure that the low temperature of the motor, don't jilt oil, so as to reduce power consumption, protect the motor.

(3) the impurity content in certain standards under control, the most the earth reducing equipment noise pollution to the environment.

(4) in turn working conditions starting and operation of the guarantee bearing flexibility, guarantee minimum power output.
 
2, general low noise motor bearing grease
In NTN bearing industry, the largest of the grease YingYongLiang, accounting for about 70% of the total amount with fat. Because this kind of grease choose the fiber soft, easy to filter of lithium soap do thickener, the use of mineral oil for base oil, it is easy to meet low-standard thrust ball bearings reduce vibration value requirements.
 
Another advantage is that good pumping sex, whether mechanical fatliquoring, or manual besmear fat, easy to operate.

3 the long life, high temperature and low noise bearing grease
Under the environment of high temperature in the use of the grease should have the following characteristics:

(1) under high temperature is not lost, that in 180 ℃ about keeping a certain temperature consistency, not soften.

(2) less oil leakage. When grease in bearing under high frequency of shear and a lot of centrifugal force and effect, lubrication can promptly back into the groove don't throw.

(3) has certain mute effect, because high temperature lubricating greases fiber is general hardness is bigger, so in the thrust ball bearings noise test the mute performance than lithium base grease.

(4) this kind of grease should have certain service life of high temperature and under high temperature has good oxidation resistance, so as to extend NTN bearings and related equipment life.
Use oil bath type lubrication system, if the oil temperature in the 60 ℃ (140 ° F) the following, and oil is intact, the replacement of a lubricating oil in a can. If the oil temperature in 60-100 ℃ (140-210 ° F), is a year need to replace four lubricating oil. If the oil temperature in the 100-120 ℃ (210-250 ° F), the need to change a lubricating oil per month. If the oil temperature in 120 ℃ (250 ° F) above, the weekly need to replace a lubricating oil.

The correct installation and maintenance is NTN bearing the normal operation of the important factors, meanwhile, must pay attention to maintain the purity of the thrust ball bearings. Bearing must protect from pollutants and moisture pollution, must have the correct installation and lubrication. In addition, bearing with the design of the listed the condition,, oil seal lubricants and forms of change cycle and special maintenance also played an important role, must pay attention on them.
