   Deep groove ball bearing structure is simple, easy to reach compared with other types of manufacturing high precision, so easily into a series of mass production, and lower manufacturing costs, the use of very common. In addition to the basic type deep groove ball bearings, there are all kinds of variations of structures, such as: deep groove ball bearings with dust cover, with rubber ring of deep groove ball bearings with snap groove deep groove ball bearings, have installed ball gap large load capacity of deep groove ball bearings, double row deep groove ball bearings.
   We recommend the following models: TAM3520 Bearing 7204CD / DB bearing bearing NUP2204 NF307ECP bearing 6017 bearing M249749 / 10 Bearing 7213C / DF bearings SCH1614-P bearing CF30-2UUR bearing 24072RHAW33 bearing 32236J2 / DF bearings SL014960 bearing NSK 6921 bearing

   nsk bearing vibration
   nsk bearing vibration of the bearing damage is very sensitive, such as peeling, indentation, corrosion, cracks, wear, etc. will be reflected in the bearing vibration measurement, therefore, through the use of special bearing vibration measuring device (frequency analyzer, etc.) measurable the size of the vibration frequency points can not be inferred unusual circumstances. The measured values due to the conditions of use or the sensor mounting position of the bearing, etc., and thus requires prior measurement of each machine will be determined after the analysis and comparison criteria.
