Thrust Ball Bearings Ambient temperature
The ambient temperature at the time of measurement is specified as 20 ° C, where the temperature of the NTN bearing, gauge block, standard part and measuring instrument must be the same. The above method of placing them on the same metal plate can achieve the necessary temperature balance as quickly as possible, Otherwise it will take hours or even days to achieve such a balance. We have to check the NTN bearing lubricant. Lubrication is very important, not only for bearings, but also for all NTN bearings. However, please note that the bearing should not add too much grease.
As far as possible so that the oil to collect residual pollutants, and then diarrhea in addition to these oils. Note: The oil is preferably filtered before use. Flow NTN bearings If used in harsh environments, NTN bearing seals and enclosures are essential because they prevent dirt from penetrating and extend NTN bearing life. Usually the shaft and bearing box almost always continue to use, NTN bearings are often to continue to use. Therefore, the structural design should take into account the removal of bearings, not to damage the bearings, shafts, bearing boxes and other parts, but also to prepare the appropriate removal tool.
Sealing method using surface contact instead of wire contact, whether it is running process, or static process, the surface contact hole seal has a good sealing characteristics. Therefore, the new ultra-capacity sealed clean roller neck NTN bearings than the traditional sealed roller neck NTN bearings have a higher reliability.
INA spherical bearings in addition to excellent quality, but also belong to very sophisticated parts, both high-performance INA spherical bearings, if used in the course of improper use, not only achieve the desired performance results, and it is easy to make INA spherical bearings Damage, in terms of lubrication we must have been noted. In addition to lubrication, INA spherical bearings in the use of the process, there are those areas need attention, Xiao Bian today and everyone to explore.
First, the use of the installation should be careful not to allow strong stamping, the motor bearing bad phenomenon solution does not allow hammer directly hit the INA spherical bearings, do not allow the transfer of pressure through the rolling body.
Second, the use of appropriate and accurate installation tools as far as possible the use of special tools, try to avoid the use of cloth and short fibers and the like.
Third, try to keep the INA spherical bearings and its surrounding environment, clean motor bearings generally use sodium-based grease even if the naked eye can not see the smile dust into the INA spherical bearings, will increase INA spherical bearings wear, vibration and noise.
Fourth, to prevent the corrosion of INA spherical bearings directly by hand to take INA spherical bearings, to wash away the sweat on hand, and coated with high-quality mineral oil and then operate in the rainy season and summer, especially pay attention to rust. In some special operating conditions, INA spherical bearings can be obtained longer than the traditional calculation of life, especially in the case of light load. INA Spherical Bearing Box Labyrinth Seal Mechanism and Influencing Factors Analysis These special operating conditions are when the rolling surfaces (rails and rolling elements) are effectively separated by a lubricating oil film and limit the surface damage that may be caused by contaminants.
In fact, under ideal conditions, the so-called permanent INA spherical bearing life is possible
