Maintaining the SKF bearings is a necessary condition for bearing operation, the typical maintenance is for bearing lubrication. Under the premise of understanding the bearing lubrication method, it is also essential to know the maintenance of the bearing system. Now we learn how to perform SKF bearing lubrication maintenance.
The grease used in the bearings must have an antirust effect, and the antirust agent is preferably insoluble in water. Grease should have excellent adhesion to form an oil film on the surface of the steel, even if the grease is full of water.
1. Keep SKF Bearings Clean
Bearings must be protected from contamination by pollutants and moisture, it must be properly installed and lubricated. The design of the bearing arrangement, the condition of the oil seal, the type of lubricants, and the lubrication cycle, also the special maintenance, all play the same important role.
Keep the bearings clean. Before inspecting SKF bearings, you should clean the surface of the bearings, and then carefully check the oil seals and surrounding parts of the bearings. If there are symptoms, be sure to replace them. Poor oil seals will cause damage. The bearing cloud shape is abnormal, which causes the equipment to stop.
2. Check The SKF Bearing Lubricants
Lubricants are very important not only for bearings but also for all SKF bearings. However, please note that it is not appropriate to add too much grease to Japanese bearings, and then it is time to replace the bearing lubricant. Oil-lubricated bearings should be refilled with fresh oil and allowed the machine to rotate at low speed for several minutes after draining the old oil, if possible.
Let the engine oil collects as many residual contaminants, and then the oil is drained. For grease-lubricated bearings, the grease remover should be used to prevent any cotton from coming into contact with any part of the bearing. Due to these residual fibers may be wedged between the rolling elements and it will cause damage, especially in bearing applications, this problem should be paid more attention to.
3. Cover The Exposed Bearings
Do not expose the bearings to contaminants or moisture when inspecting the bearings. If work is interrupted, the machine should be covered with a greased plastic sheet or similar material. If the unshielded bearing is to be cleaned without disassembling and inspection may be performed, it should be cleaned with a brush applied with a petroleum solvent and then wiped with a lint-free cloth or blown with compressed air.
Use a small mirror together with a probe similar to that used by dentists to inspect the bearings' track surface, retainer, and beads. Do not clean bearings with sealed caps or dust; you can just wipe the outer surface. If the bearings are damaged, it needs to be replaced. It is far more economical to replace the bearings during the period of regular downtime maintenance than the loss of sudden downtime due to damage to the bearing.
Through these three steps, you can well maintain your bearings, significantly increase their service life, and save your running costs. Not only the surface quality of SKF bearing workpieces is not good, but the resistance to corrosion of the workpieces is reduced. When the SKF bearing workpiece is severely overheated, the crystal grains are coarse, and at the same time, the amount of the eight iron wire in the steel is increased, which may cause the workpiece's hot workability to deteriorate. lcrl8Ni9Ti stainless steel accessory or flange parts are prone to produce orange peel-like surface defects when overheating occurs.
