Analysis on performance of NSK bearing lubrication method

When chromium steel and stainless steel as NSK bearing material is detected when the advantages of and found that they not only have Rust prevention role. Chromium was NSK bearings are the most common materials. It is harder than stainless steel, using a longer life. At higher temperatures, however, its performance is not up to much.
In 120C under high temperature, it will great deformation, load decreases. 150C high temperature it can withstand, but moments 150C or higher temperatures will reduce the life of NSK bearings. Heat treatment can make high temperature bearings are subjected to transient 170C.
NSK bearings designed to reduce internal friction of bearings of lubrication and friction loss, prevent burning viscosity, lubrication effectiveness as follows.
⑴. reduced friction and friction losses.
Constituted of NSK bearing rings, touching parts of the rolling element and cage to prevent the metal contact, reducing friction and wear.
⑵. extension of fatigue life.
Rolling fatigue life of bearings, rotating, rolling contact surfaces lubricated well, is extended. Conversely, low viscosity oil, lubricant film thickness is not good, is shortened.
⑶. draining friction heat, cooling
Circulation to the oil law can be discharged from friction heat with oil, or by an external heat from cooling. Prevent the bearings overheating, prevent lubricants's own aging.
⑷.
Also to prevent foreign bodies penetrated bearing internal, or prevent rust, corrosion effects.
Lubrication method:
NSK bearing's lubrication method, divided between grease lubrication and oil lubrication. For NSK bearing play function very well, first of all, to select the appropriate conditions of use, the use of the purpose of lubrication method. If only consider lubrication, oil lubrication of lubrication advantage. However, grease lubrication around bearing structure can be simplified like, compare the advantages and disadvantages of grease lubrication and oil lubrication.
