Lubrication and cleaning of NSK imported bearings
Lubrication and cleanliness of NSK imported bearings are very important. Cleaning the surface of NSK imported bearings is what we must do before inspecting imported bearings, after which we disassemble the surrounding parts of the bearing. Everyone should pay attention to the fact that the oil seal is a very fragile part. You need to be extra careful when inspecting and disassembling. Do not use excessive force to avoid damage to the parts. Then carefully check the oil seal of the bearing and its surrounding parts, if it has shown bad symptoms, be sure to replace it, otherwise the bearing cloud will be abnormal and cause the equipment to stop.
Secondly, we have to check the lubricants of NSK imported bearings. Lubrication is very important, not only for imported bearings, but also for all imported bearings. But please note that too much grease should not be added to the bearing. The inspection method for imported bearing lubricants is: apply a little bit of lubricant and rub between the two fingers. If there are contaminants, it can be felt; or apply a thin layer of lubricant on the back of the hand, and then perform a light-sealing inspection . Then it is time to replace the lubricant of the bearing. After using oil-lubricated bearings, after purging and removing the old oil, if possible, fill in fresh oil and let the machine rotate for a few minutes at a low speed. Try to collect the remaining contaminants in the oil as much as possible, and then flush out the oil. Note: The oil is very well filtered before use. When replacing the grease with grease-lubricated bearings, the filter remover used should avoid any part of the imported bearing with cotton material attached to the corner. Because these residual fibers may be wedged between the rolling elements and cause damage, especially the application of small bearings should pay more attention to this problem.
Finally, it is necessary to pay attention to covering the exposed imported bearings. When inspecting the bearing, never expose the bearing to contaminants or moisture. If work is interrupted, the machine should be covered with greased paper plastic sheet or similar material. If the unmasked bearing is cleaned without disassembly and inspection may be performed, it should be cleaned with a paint brush moistened with petroleum solvent, and then dried with a lint-free cloth or dried with compressed air (be careful not to The bearing assembly starts to rotate). Use a small mirror or a probe similar to that used by dentists to inspect the bearing track surface, retainer and beads. Do not clean the sealed cover or dust-proof bearing; just wipe the outer surface. If the bearing is damaged, it needs to be replaced. It is much more economical to replace the bearings during the regular maintenance period than the loss caused by the sudden shutdown due to the damage of the bearing.
