How to solve the heating problem of SKF bearings

Maintaining the bearing is a prerequisite for bearing operation, and the common maintenance method is to lubricate the bearing. How to choose the lubrication method of the bearing, on the premise of understanding the lubrication method of the bearing, it is also necessary to have an understanding of the maintenance of the bearing system. The following analysis how to carry out the lubrication maintenance of SKF bearings.
 
Keep the bearings clean
Before inspecting SKF bearings, the surface of the bearing should be cleaned, and then the oil seal of the bearing and its surrounding parts should be carefully inspected. If a bad symptom appears, it must be replaced. A bad oil seal will cause damage and make the bearing cloud-like. Normally causing equipment downtime.
 
Check bearing lubricant
Lubricant is very important not only for bearings, but also for all SKF bearings. But please note that it is not advisable to add too much grease to Japanese bearings. Then it is time to replace the lubricant of the bearing. Bearings lubricated with engine oil, after purging and removing the old engine oil, if possible, fill in fresh engine oil and let the machine rotate for a few minutes at a low speed. Try to make the oil collect the remaining contaminants, and then remove the oil. When replacing the grease with grease-lubricated bearings, the filter remover used should avoid any part of the bearing with cotton material coming into contact with it. Because these residual fibers may be wedged between the rolling elements and cause damage, especially bearing applications should pay attention to this problem.
 
Pay attention to covering exposed bearings
When inspecting the bearing, do not 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 disassembling and inspection is possible, it should be cleaned with a coating brush moistened with petroleum solvent, and then dried with a lint-free cloth or dried with compressed air.
 
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 bearing during the regular maintenance period than the loss of a sudden shutdown due to a series of bearing damage.
