The defect of the bearing is expensive!

SKF hybrid ceramic bearing is a bearing steel ring and silicon nitride ( Si3N3) Made of a combination of rolling body. This kind of bearing in addition to have good electrical insulating properties, and also to operate at a higher speed to, in the big local applications, service life is longer than the traditional bearing steel bearing. Hybrid ceramic bearing hybrid ceramic bearing to further improve the electrical insulation properties, especially about the application of high frequency inverter. SKF hybrid ceramic bearing has the following outstanding performance, enable it to in ultra high speed fine much-loved equipment and frequency conversion motor, etc. Low insulation performance. The conductive silicon nitride rolling element bearing does not have a current through the maintenance, so as to prolong the life of the use of the bearing, due to the destructive nature of the bearing current will soon be shorten its use life. Low density is low. Bearing grade silicon nitride than the density of the same size of the roller bearing steel rolling body low 60%, this means that the light weight, small inertia, superior performance, rapid start-up speed is higher. Low friction coefficient is low. Silicon nitride rolling body density low, coupled with the low friction coefficient, can greatly reduce the bearing temperature in high speed. Temperature operation can prolong the using life of bearing and smooth agent. Low hardness and elastic modulus is high. Silicon nitride roller hardness can progress bearing abrasion resistance, stiffness in the environmental pollution and using life. Steel rolling body excessive rolling solid pollutants, due to plastic deformation, will be on the raceway and rolling body composition has a bump on the edge of the indentation. Due to continuous excessive rolling roller convex edge, part of the higher stress will cause peeling off, causing premature failure of the bearing. However, hybrid ceramic bearing on excessive rolling response to different damaged area. Because of the silicon nitride high hardness, grasp the bulge of the indentation rolling edge smooth, until the raceway restore smooth, this will reduce the part of the stress and the timing of the peeling, thus significantly extend the using life of bearing. Low resistance to pseudo brinell indentation. When the bearing is in a stationary state, due to the vibration, the risk of hair faking brinell indentation. Pseudo brinell indentation is produced on the rolling path mark, will eventually cause premature bearing failure. Ceramic roller to replace steel rolling body, pseudo brinell indentation will be significantly reduced. Low silicon nitride and the adhesion between steel appearance wear risk reduction. Even in a smooth condition not abundant condition, silicon nitride and the adhesion between steel appearance wear risk is low. This makes the application of hybrid ceramic bearing in high speed and high acceleration place or lack of dynamic pressure oil film application is running time will be longer. Low thermal shrinkage coefficient is low. Silicon nitride heat shrinkable coefficient of rolling body is lower than the same size of the bearing steel roller. This means that within the bearing on temperature gradient less sensitive, can more accurately control of pre-load and clearance. Low fat smooth long service life. Hybrid ceramic bearing friction heat produced less than all of the same size steel bearing, especially under the condition of high speed. Lower bearing operating temperature for increasing the using life of the bearing and complementary smooth time distance has the beneficial effects. According to the application site and operating conditions, the use of smooth fat can prolong life for at least two times. SKF hybrid ceramic bearing so many excellent performance is very worth for use, the only defect is a bit expensive! So the hybrid ceramic bearing only on high speed precision equipment, high voltage variable frequency motor and generator equipment use. Is no other, in the middle of the bearing can't deal with by the hybrid ceramic bearing to bear.
