1 and in the process of using NTN bearing, regular cleaning is very first. How accurate cleaning bearing? First the bearing tear open next five, at first the way such as well with photography appearance record. In addition, to make sure the amount of residual lubricant and lubricant sampling, and then clean bearing.

2, bearing washing and cleaning points thick fine cleaning suspension, and can be used in the bottom of the container put metal grids.

3, crude washing, be in oil and grease or brush clear sticky content. If this time in oil migration change bearing, note blend for other foreign material, mutilate rolling face.

4, fine cleaning, slowly in the oil migration change bearing, must be hard suspended.

5 fill the clear, use for neutral no water diesel or oil, sometimes using temperature according to demand of the lye, etc. No matter use what kind of cleaning agents, want to often filter confrontation clean.

6, cleaning, immediately in NTN bearing on temporary antirust coating or fat.

Want to let more long import bearings for mechanical operation doing the service, the regular NTN bearing a routine testing is very be necessary, through the test can effectively detect mechanical operation of the problems, the solution of the problem to get good, effective increase the service life of the bearings.

In the detection of main observation bearing the rivet when head have skewed, relaxation welding position is correct. Maintains a good or bad of welding. Welding point is too small, a welding not firm, or welding excessive cause card problems such as the ball. Are all in the detection process of import bearings need special attention to place. There is also some problems need to be aware of.

On the bearing local detection. First of all in the environment of the import bearings examinations should have a light in the environment, had better be astigmatism, in order to better on the bearing external observer, look at the surface and no crack and other different. Such as machinery in the process of cloud wear, Nick, pressure touch, will lead to bearing device migration, lead to bad position device, cause flat load and stress concentration, the modelling of bearing the precision and the service life of reduced.

In addition working environment is special attention to have water or contaminants, these the most likely cause bearing rust, rust is cause NTN bearing installation is bad, the early wear, can lead to more serious bearing to direct scrap. So in use process waterproof special attention.
