Lubrication is important for imported bearings

Core Tip: In the article on checking the faults and treatment of imported bearings in operation, the importance of lubrication for imported bearings is mentioned. Now let's talk about the lubrication for imported bearings.
The importance of lubrication for imported bearings is mentioned in the article "Checking the faults and handling of imported bearings in operation". Now let's talk about the effects of lubrication on imported bearings. Whether the lubricant or lubrication method is correct or not will greatly affect the life of the imported bearings.

    The impact of lubrication on the performance of imported bearings can be divided into the following aspects:

    1. Firstly, lubricate the parts of the imported bearings to reduce the friction and wear of the imported bearings;

    2. The rolling contact surface of the imported bearing often forms an appropriate oil film to prolong the fatigue life of the imported bearing;

    3. The heat generated by friction or other reasons inside the imported bearing is removed by lubrication;

    4, through the lubrication can achieve the effect of rust and dust on the imported bearings.

    The two main lubrication methods for imported bearings are grease lubrication and oil lubrication.

    Grease lubrication has a sealing method in which the sealed bearing is filled with grease in advance, and a filling and fat filling method in which the inside of the outer casing is filled with an appropriate amount of grease and replenished or replaced at intervals. In addition, for machines that require multiple bearings to be lubricated, a centralized grease supply method that connects the pipes to each lubrication location is also used. Grease lubrication can be used after filling the grease for a long time without replenishing, and the structure of the sealing device is relatively simple, so it is widely used. Oil lubrication is relatively simple. Regular lubrication can increase the service life of imported bearings.

Matters needing attention during the use of imported bearings

Core Tip: In addition to excellent quality, imported bearings are also very precise parts. They are high-performance imported bearings. If they are used improperly during use, they will not achieve the expected performance.
In addition to excellent quality, imported bearings are also very precise parts. They are high-performance imported bearings. If they are used improperly during use, they will not achieve the expected performance results, and it is easy to damage imported bearings. Everyone must have noticed. In addition to lubrication, in the use of imported bearings, there are those aspects that need attention, Xiaobian today and everyone to discuss.

    First, 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.

    Second, use appropriate and accurate installation tools

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

    Third, try to keep the imported bearings and their surroundings 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.

    Fourth, to prevent corrosion of imported bearings

    When taking the imported bearing directly by hand, wash the sweat on your hands thoroughly and apply it with high-quality mineral oil before handling. In the rainy season and summer, pay special attention to rust prevention.

    Under certain special operating conditions, imported bearings can achieve longer life than traditional 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 bearing life is possible.
