Bearing maintenance cycle
How often should the bearings be serviced? Bearings can theoretically be used for 20,000 to 80,000 hours, but the specific life depends on wear and work intensity during use.
Dry the cleaned bearing with a dry rag, and then soak it in anti-rust oil. In this process, the bearing should be completely in contact with the anti-rust oil, and the bearing should be rotated continuously, so that the oil film formed by the anti-rust oil can cover the surface of the bearing to achieve the purpose of anti-rust.
Next, use lithium-based grease and butter, which should be evenly coated on the surface of the bearing, including the inner and outer rings, wheels, and cage, and rotate the bearing while wiping, so that the butter can really enter the inside of the bearing and play a full lubricating role. First, put the bearing in gasoline to clean it, wipe off the sludge and dust remaining on the bearing, and gently wipe and polish the bearing with metallographic sandpaper until there is no roughness by hand.
The final process is packaging. In order to save costs, we "turn waste into treasure", cut the cement packaging bags scrapped in the warehouse into packaging bags of suitable size, wrap the bearings tightly, package them well, label the specifications and models of the bearings, and put them back on the shelves for storage.How to maintain the bearing
In order to give full play to the bearing and maintain its proper performance for a long time, it is necessary to do regular maintenance (regular inspection). Early detection of failures and prevention of accidents through appropriate periodic inspections are important for improving productivity and economy. Storage Bearings are coated with an appropriate amount of anti-rust oil and packed with anti-rust paper when leaving the factory. As long as the packaging is not damaged, the quality of the bearings will be guaranteed. However, for long-term storage, it is advisable to store it on a shelf 30cm above the ground when the humidity is lower than 65% and the temperature is about 20°C. In addition, the storage place should avoid direct sunlight or contact with cold walls. In addition, when removing the bearing for inspection, first make a record of the appearance by means of photography or the like. Also, confirm the amount of remaining lubricant and sample the lubricant before cleaning the bearing.Bearing maintenance steps
1) Remove the wheel first, remember to put the screw away, it will be troublesome if it falls.
2) Remove the bearing. The core of some wheels is very tight, and the bearing is difficult to remove. Just use a hexagonal wrench (the one that removes the screw) to dig it out. Rest assured, the bearing is not easy to break.
3) First, use a toothbrush to brush off the dirt on the surface of the bearing. You can do without this step, no problem.
4) The side cover of some bearings is detachable, while others are not. First judge whether the bearing is detachable.
5) If it is detachable, it is very simple. Use a flat-blade precision screwdriver to pry up the C-ring at the notch of the C-ring, and then remove the side cover, just remove one side.
6) If it is not removable, it is more troublesome, and a destructive method should be used. Use a precision screwdriver to penetrate the seam of the side cover, and pry the side cover up hard, don't doubt, that's it, but the side cover can't be put back on. As long as one side is removed, it will be destroyed by removing both sides.
7) Remove one side cover of all the bearings, and you can start washing. Pour the stained oil into the bowl, throw the bearing down and stir it up.
