SKF bearing lubrication methods have several kinds, and various models of bearing and each type of bearing in use of lubrication all is not the same that favor SKF to maximize the service life of the bearings, is the performance of the mechanical equipment in the highest efficiency of the state.

1, solid lubrication
In some special use conditions, a solid lubricant grease to join in, such as join three to 5% of the no. 1 mos2 can reduce wear, improve the compressive heat-resisting ability, for high temperature, elegant, high vacuum, corrosion resistance, resistance to radiation, and extremely low temperature, and other special conditions, the solid lubricant to join engineering plastic or powder metallurgical materials, can be made with self-lubrication performance bearing parts, if use adhesive bonding solid lubricants roll in the way, and maintains a and roller forming lubrication film, to reduce the friction and wear a certain effect.

2, oil lubrication:
Viscosity is an important characteristic of lubricating oil, the size of the viscosity of oil directly influence the liquidity and formed between the friction surface of the oil film thickness, SKF bearing operating temperature lubricant viscosity is generally 12-15 CST. The GaoYingXuan speed low viscosity, the more heavy load rappel/abseil stations should be higher viscosity. Commonly used lubricating oil have JiXieYou, high speed JiXieYou, turbine oil, compression oil, transformer oil, cylinder oil etc.

Oil lubrication methods include:

A. bath lubrication oil
Oil bath lubrication is the most common lubrication method, suitable for low, medium speed bearings lubricated bearing part of the dip in the slot, by rotating bearing parts lubricant with on, and then come back to the oil tank face should be slightly lower than the minimum of the roller center.

B. drops of oil lubrication

Drops of oil lubrication is suitable for the need to supply quantitative lubricant SKF to bearing elements, dripping oil amount general every 3-8 seconds a advisable, too much oil amount will cause bearing temperature increased.

C. circulating oil lubrication

Be filtered with oil pump oil conveying to bearing parts, through the bearing of the lubricating oil filter again after cooling after use. Due to circulation oil can take away a certain quantity of heat, make bearing cooling, reason this law is applicable to the high speed bearings components.

D. spray lubrication

The compressed air with dry by spray and lubricating oil mix formation oil mist, jet bearing, the air can effectively make bearing cooling and prevent the impurities invasion. This method is suitable for high speed, high temperature bearing parts lubrication.

E. jet lubrication

With oil pump will be high pressure oil through the nozzle to shoot to bearing, into the oil in the bearing of the bearing the other end into the oil. SKF bearing in high speed rotating, rolling body and maintains a also with very high rotation speed around to air form air, using general lubrication methods, it is hard to lubricating oil to bearing, then must use the method of high pressure jet will lubricating oil spray to bearing, nozzle should be put in the position of the inner circle and maintains a center between.

SKF bearing kurtosis is not big, now use data collector is more common. But in practice to pay attention to the skills. For vibration is not big. The spectrum of the complex vibration signal, the scene is trouble-free situation hard to judge, will vibration signals back to the computer to carry on the precision analysis. At this time, first routine analysis, check the vibration velocity spectrum and bearing kurtosis is close to the standard, and then use power spectrum investigation vibration energy is overweight, if the power spectrum is not big, observation in the spectrum of the various frequency component. If the corresponding frequency power frequency spectrum line The Times, it should focus on the structure of fault search unit; If power frequency number times, appear more small digital frequency, it should focus on the search SKF bearing its frequency, if any, bearing fault exist, if not, rule out other parts fault should be cause for alarm after, strengthen the monitoring. The actual found that many vibration not to exceed bid, and appear bearing fault cases. Once appear bearing characteristic frequency or close to bearing a characteristic frequency spectrum, it should be judge bearing fault exist, then according to the size of the amplitude of the trend analysis or arrange maintenance.
