Precautions for the use of SKF outer spherical bearings during use

SKF outer spherical bearings are precision parts, except for the lubrication and attention, and the use of SKF outer spherical bearings must be very cautious. It is a high-performance SKF outer spherical bearing. If it is used improperly during use, it will not achieve the expected performance, and it will easily damage the SKF outer spherical bearing and cause unnecessary loss.

So, in order to avoid unnecessary losses,

We should pay attention to the following points when using SKF outer spherical bearings:

First, try to keep the SKF outer spherical bearing and its surrounding environment clean

Even if the smiling dust that is invisible to the naked eye enters the bearing, it will increase the wear, vibration and noise of the bearing.

Second, use the installation carefully

Strong stamping is not allowed. It is not allowed to directly hit the bearing with a hammer. It is not allowed to transmit pressure through the rolling elements.

Third, use appropriate and accurate installation tools

Try to use special tools and try to avoid using cloth and short fibers.

Fourth, to prevent the corrosion of SKF outer spherical bearings

When taking SKF outer spherical bearings directly by hand, wash the sweat on your hands and apply high-quality mineral oil before handling. Pay special attention to rust prevention during the rainy season and summer.

However, under certain special operating conditions, SKF outer spherical bearings can achieve longer life than conventional calculations, especially at light loads. These special operating conditions are when the rolling surfaces (tracks and rolling elements) are effectively separated by a lubricant film and the surface damage caused by contaminants is limited. In fact, under ideal conditions, the so-called permanent SKF outer spherical bearing life is possible.

Analysis affects the life of KOYO needle roller bearings for maintenance and maintenance

In order to make the KOYO needle roller bearing parts have a large compressive stress on the surface after quenching and tempering, a carburizing or nitriding atmosphere may be introduced during quenching heating to perform surface carburizing or nitriding for a short time. Since the actual austenite carbon content is not high when the steel is quenched and heated, it is much lower than the equilibrium concentration shown on the phase diagram, so carbon (or nitrogen) can be absorbed. Depending on the application, it is necessary to select bearings for special requirements in terms of precision, clearance, cage structure, grease, etc. However, there is no certain order for selecting bearings. Rules, priority should be given to the conditions, performance, and related matters required by KOYO needle roller bearings, especially for practical use.

In order to fully utilize KOYO needle roller bearings and maintain their proper performance for a long time, regular maintenance (regular inspection) must be performed. Through proper periodic inspections, early detection of failures and prevention of accidents are important to improve productivity and economy. Lubrication method: KOYO needle roller bearing lubrication method, divided into grease lubrication and oil lubrication. In order to make the bearing function well, first, choose a lubrication method that suits the conditions of use and the purpose of use. Lubricity of oil lubrication predominates if only lubrication is considered. However, grease lubrication can simplify the structure of the KOYO needle roller bearing structure, and compare the advantages and disadvantages of grease lubrication and oil lubrication.

When the original microstructure in the steel is constant, the carbon content of the quenched martensite (that is, the austenite carbon content after quenching heating), the amount of retained austenite and the amount of undissolved carbide mainly depend on the quenching heating temperature and the holding time. As the quenching heating temperature increases (time is constant), the amount of undissolved carbides in the steel decreases (the carbon content of the quenched martensite increases), the amount of retained austenite increases, and the hardness first increases as the quenching temperature increases. After reaching the peak, it decreases as the temperature increases.

As long as the bearings in order to maintain the original performance as intact, maintain, maintain, and put in the first place to prevent accidents, ensure operational reliability, improve productivity, and economy. Corresponding mechanical operation and maintenance work standards, regular, best conditions. This includes monitoring the operating status, replenishing or replacing the lubricant, and checking it regularly. As a problem of maintenance operation, KOYO needle roller bearing have been rotated, vibrated, temperature, lubricated, and so on.
