Ceramic bearings and steel bearings have those little advantages

 Kunshan Bearings: In recent years, the country, both inside and outside of the ceramic bearings in research, development has achieved fruitful results and substantial progress. In machine tools, chemicals, aerospace and other fields has been applied and play a magical effect.
       Compared with steel Stainless steel slewing bearing with ceramic bearings as magical advantages:
       1, high speed and acceleration - can dn value over 3 million operating conditions, and the skid, wear and heat can be reduced;
       2, long life, resistance to wear - full ceramic bearing fatigue life expected to be 10-50 times longer than steel bearings, hybrid ceramic bearings, steel bearing life than the life of a high 3-5 times;
       3, the required minimal lubrication - low coefficient of friction ceramic materials, ceramic bearings lubricated by oil, the lubricating oil or depleted thinning cases, the lubricating ability is still lower than the conventional steel bearing lubricants commonly used;
       4, abrasion - since the ceramic material is an inert material, it is more resistant to corrosion and abrasion;
       5, rigidity, - ceramic materials because of high modulus of elasticity, rigidity than ordinary steel bearings Large 15-20%;
       6, high temperature - full ceramic bearings can work at temperatures above 500C;
       7, the torque low - according to the structure, ceramic bearing torque decreases by about 1/3;
       8, non-magnetic non-conductive - ceramic bearings are not subject to magnetic, electrical damage.
       With further research and a lot of breakthroughs in manufacturing technology, ceramic bearings in high-speed, high temperature, corrosion and other areas of applications will be very considerable.Take a clean white filter paper, drip a few drops on the filter paper until the oil leak, if the surface has black powder, a resistive touch astringent sense, then the lubricant inside has a lot of impurities, good no lubricant powder, hand feels dry and smooth, and yellow marks.
3 oil flow observation
Kunshan Bearings: Take two measuring cups, one containing the lubricating oil to be checked, the other empty on the table, will be filled with oil cup held high 30-40 cm away from your desk and tilt, allow oil flow slowly to the empty cup to observe the flow of good quality lubricating oil flow should be slender, uniform, continuous, if there is oil flow unsteadiness, sometimes with large shed, then say oil has gone.
