NSK bearing field, most applications of this grease, total quantity of fat 70%. Because this type of grease made of fiber is soft, easy to filter the lithium SOAP thickener, use mineral oil as the base oil, it is easy to meet the requirements of middle and low vibration value stainless steel bearings. Another advantage is that it has a good pump, whether machinery greasing, are hand-painted resin, are simple. Moreover, the low price of the grease can greatly reduce the cost of bearing.
First of all, it should be pointed out is that keeping stainless steel bearings are lubricated and clean is very important. So when we went to check the bearings, you should clean the NSK bearing surface and perimeter of the disassembling bearing parts. We should note that oil seals are very fragile parts, inspection and dismantling need to be especially careful when to use excessive force, so as to avoid the damage of parts. Then carefully check the bearing oil seals and adjacent parts, if you have bad symptoms, be sure to replace the bad oil seals will result in damage to, bearing clouds caused by abnormal equipment downtime.
Secondly, we also check NSK bearings lubricant. Lubrication is very important, not just for bearings, bearings for all. But please note that the bearing should not add too much grease. On checking method for the bearing lubricant is: got little bit of lubricant on the friction between the two, if the presence of pollutants, is feeling left out; or spread a thin layer of lubricant on the back, and then proceed to rays. Then replace stainless steel bearing lubricant. After the purging old engine oil, oil lubrication of the bearings, and, if possible, should be grouted with fresh engine oil and make the machine at low speed of rotation for a few minutes. Residual oil as much as possible to collect pollutants and diarrhea in addition to these oils. Note: engine oil before use, it is best to filter. NSK bearings using grease lubrication grease is replaced, use Joe should be avoided with cotton corners to any part of the bearing. Fiber because these residues may be wedged in between the rolling and cause damage, especially small bearing application should pay attention to this issue.
In order to extend the life of stainless steel bearings, installation is a step that cannot be ignored, how to provide the installation accuracy will directly affect the bearing life, so before installing NSK bearings, first of all to the precision of the determination of bearing, and then not found means increases.
To properly preload the NSK bearing spindle, speed gradually increased to around speed, to apply bearing "break-in" effect can increase the cycles of spindle running accuracy.
