Load Ratings of 6902 Ceramic Bearing

Therefore, the contact stress between rolling elements and races of ceramic bearing would be significantly higher than that of steel bearing, under the same amount of load. The following table shows the evaluation of load ratings of ceramic bearings versus steel bearings.

The load capacity of ceramic bearings is accordingly decreasing when working temperature is increasing. HSC suggests choosing a larger load rating capacity bearing when using a full ceramic bearing for your application.

Due to the brittleness of ceramics, full ceramic bearings are not capabale of withstanding too much impact load. The outer races or inner races will generate cracks or even suddenly break under a certain amount of impact load.

characteristics of 6902 ceramic bearing

Detailed introduction to 6902 ceramic bearing:

         We supply a comprehensive range of ceramic bearings.

          Ceramic bearings usually weigh 40% less than ball bearings and roller bearings for its size and material.

          Ceramic bearings are typically constructed with a ferrous inner and outer ring with ceramic balls in stead of steel.

           They takes many advantages over steel bearings, such as higher speed and acceleration capability, increased stiffness, lower friction and more.

           Ceramic bearings are available in all standard industry categories such as angular contact bearings, thrust bearing, pillow block bearing, needle roller bearings and other roller bearings.

          Ceramic bearings are made from Si3N4 which have greater hardness than steel.

Ceramic bearing balls have smoother surface than most steel bearings balls.

They require less lubricant and exhibit lubrication degradation, which results in increased bearing life.

          Ceramic bearings are applied on high temperature, high speed, friction, semiconductor and food processing and so on.
