Rolling SKF bearing maintenance problems

Rolling bearings are a lot of mechanical parts produced, and the manufacturing precision is very strict, and the level of specialization of skills is very high. Therefore, for the types of SKF bearings that are easily bought, it is more cost-effective to purchase than to repair. Next, I thought about the repair problem of SKF bearings, namely:
(1) Many SKF bearings of the same type used in large-scale construction sites are mainly subjected to rolling wear, euphemism or fretting abrasion, especially for damaged parts, which are mostly brackets or rolling elements, while ferrules or washers are still Have repair value;
(2) Some types of SKF bearings that are difficult to purchase, have no spare parts after the failure, and have to be repaired, especially SKF bearings;
(3) SKF bearings have minor damage, such as the slight rust that occurs during the inventory period, and the slight fretting abrasions that occur during the transportation process.
(4) Large and extra large SKF bearings, which are not damaged or have been damaged, but the parts have not been seriously damaged, or valuable SKF bearings must try to extend their useful period of use;
In addition to economics, the repair of SKF bearings also has its skills, which requires repairers to fully investigate the technical requirements of SKF bearing response, and the structural, technical and data characteristics of SKF bearings and their parts, otherwise it is difficult The repair of the SKF bearing has the required results.
First, the economic benefits of SKF bearing repair:
In general, SKF bearings are small in number and large in number, and the price of a single SKF bearing is high, or the structure of the SKF bearing is simple. Large size, the lower the cost of repair, the higher the economic efficiency.
In addition, the operation status of SKF bearings is monitored, and there are plans to repair the SKF bearings in a fall, and you can get twice the result with half the effort. Compliance with sound processes, efficient repair equipment and things, and assistance from professional SKF bearing plants can help improve economic efficiency.

NTN bearing operation and maintenance

     1 Check the operating temperature of the NTN bearing, which is required to be below 65 degrees.
     2 Check the inside and outside of the NTN bearing for pitting, check the pits, cracks and other defects of the NTN bearing.
3 Check the axial movement of the moving parts. Mainly whether the clearance of the NTN bearing meets the requirements.
Reliable maintenance work is the main means to ensure long-term operation of NTN bearings. When the equipment is running for a period of time, professional technicians should be inspected and maintained in time, mainly in the following aspects:
4 Lubricating oil or grease lubrication, should be replaced or added in time, but not too much, requiring one-third to one-half of the lubricating oil, one-third of the grease.
