INA bearing called preventive maintenance or planned maintenance means: INA bearing device after a certain period of time to cloudy sky, regular replacement. The preventive maintenance for is still a large number of plants so far performed. The most significant disadvantage, preventive repair, replacement and repair cycle, to make sure they tend to rely on subjective judgment and statistical methods to estimate indirect and statistical methods to estimate indirect components such as INA bearing life, with blindness, some so, add in a certain life bearing type powder from a part of the am am, blind forces of nature is more prominent, and alone or with the human sensory organs equipment state simple detection tools (such as a hammer hand, auscultation stick, thermometer etc..) To check, is difficult to capture the feeling of failure, and check the internal signal equipment failure or human organ will not judge, especially personalized in determining the lack of quantitative, easily lead to wrong judgment,. Therefore, strictly speaking, preventive maintenance, unable to adapt to the modern equipment. Preventive maintenance is another question: can not make full use of INA bearing INA bearing life, lead to excessive consumption, the formation of "excess" state of repair.
INA bearing check failed, mainly is the outside diameter, inside diameter, width, etc.. The inner diameter, outer diameter of precision bearings, the main quality indicators of performance, will cause the bearing fault of large diameter, size precision of discrete, ultra difference phenomenon is more serious.
The inner diameter, outer diameter of common problem is INA bearing bore, excircle machining size does not conform to the standard value, dispersed, diameter and width excessively, resulting in bearing and assembly, the Council did not even affect the bearing use. Found that the quality supervision and inspection for seven categories of products bearing the provincial product problems, inspection department should be in accordance with the relevant laws, regulations, take effective measures, supervise the unqualified products production, distribution enterprises seriously rectification, the implementation of post processing.
