Every so often I all saw some people in used the ntn bearing the time life all not to use up have replaced, like this is wastes very much today gives everybody in this me to introduce could let the Roller bearing life biggest method, before we had also said chose the high accuracy the bearing method, all bearings before installment all should preserve in their original packing.They need to remain cleanly, do not have the moisture, in the relative constant temperature environment.The hoop bearing should be far away the dust, the water and the corrosive chemical substance.
Imports the bearing the installment is whether correct, is affecting the precision, the life, the performance.Therefore, the design and the assembly department must study fully regarding the Roller bearing installment.The hope must defer to the work standard to carry on the installment.Work standard project usual as follows:
(1) cleans the bearing and the bearing correlation part;
(2) inspection correlation part size and precision work situation;
(3) installment;
(4) installs the good ntn bearing the inspection;
(5) supplies lubricant.
Before once the detailed understanding sifted pulls the bearing some questions, knew spread in advance has the fat (or seal) the bearing needs specially carefully, after because the fat passed through the long time memory the density to be able to change.When like this bearing first use, can have certain degree rotation noise.Therefore, this kind of ntn bearing placement time should according to the principle which advanced leaves first control.
We should know are the bearing collar plane of rotation and the trundle part surface roughness usually are 1/10 μm, the so smooth surface the damage which creates to the pollutant is extremely sensitive.Between the plane of rotation lubricant film usually is 0.2~1 μm, but is bigger than the lubricant particle size the pellet impurity to be able to receive the trundle part the over-rolling to have the local pressure in the bearing steel, finally can cause the permanent fatigue of materials.The profession experts estimated that, in the premature Roller bearing expiration situation 16% is as a result of not the correct installment, this is the ntn bearing life display greatly biggest only method.
