In a given operating conditions, SKF bearings can be obtained relatively longer than the traditional calculation of life, particularly in the light of circumstances. These special conditions is that when scrolling (rail and scroll) were effectively separated by a lubricating oil film and limit the pollutants may cause surface damage. In fact, under ideal conditions, the so-called permanent life of SKF bearings are possible.
SKF bearing lubrication purposes:
Lubrication of rolling bearings in order to reduce internal friction bearings and friction losses, preventing the burning stick, the lubrication effectiveness is as follows.
(1), reduced friction and friction losses.
Forming the SKF bearing rings and rolling elements and cage of mutual contacts to prevent metal contact, reducing friction and wear.
(2), longer fatigue life.
Fatigue life of rolling bearings, rotating, rolling contact surfaces lubricated well, is extended. In contrast, low oil viscosity, oil film thickness is not good, is shortened.
(3) the friction heat, cooling, foul.
Circulating oil discharges can be used, such as the oil law by friction heat, or by an external heat coming from cooling. Prevent bearing overheating to prevent ageing of the oil itself.
(4), other
Also to prevent foreign bodies penetrated bearing, or prevent rust, corrosion effects.
Methods of lubrication:
SKF bearing lubrication method, there are grease lubrication and oil lubrication. In order to make it better play function for SKF bearings, first of all, to select suitable for conditions of use, use of methods of lubrication. If only lubrication, oil lubrication of lubrication-dominated. However, grease lubrication can be simplified bearing structure like that around, compare the advantages and disadvantages of grease lubrication and oil lubrication.
