Reasonable to determine the bearing life bearing in terms of the application by a very important thing.NTN bearig
Therefore, in determining the service life of bearing, corresponding to the mechanical category and a variety of wor king conditions and reliability requirements and other

factors to be a comprehensive assessment to determine.double row bearing

Conditions can not be used as follows:

Infrequently used instruments and equipment recommended by the life of 300-3000

Short-term or intermittent use, the middle of usage does not lead to serious consequences for the machine, such as manual machinery, installation crane, automatically sent to

the service life of materials and devices recommended 3000-8000

Intermittent use, interrupt the use of machinery will lead to serious consequences, such as the recommended service life of power plant auxiliary equipment, assembly line gear,

belt conveyor, workshop crane 8000-12000

8 hours a day, but do not often work at full load the machine, such as the recommended service life of motor, gear, crushers, cranes and general machinery 10000-25000

8 hours a day, the full load of machinery, such as the recommended service life of machine tools, engineering machinery, centrifuge, 20000-30000
