Full Ceramic Zirconia deep groove ball bearing 6204 2rs with high quality
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 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.
Advantages of Ceramic Bearings
uessentially increased life time
uhigh stiffness because of high Young’s modulus,lower vibration
uwear resistance and cost effective lubrication
uelectrical insulation and non-magnetism
uhigh temperature resistance up to 1000oC
uhigh corrosion resistance to most acids and alkalies
