Product Description
advantage of ceramic bearing
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.
deep groove ball bearing
Deep groove ball bearing is suitable for Sustain radial,acial,or compasite load. Provide both high-running accuracy &high-speed operation , Can replace high speed angular contact ball bearings. Application : Power Tools,Fans,Washing Machines,Pumps,Electric Motors,Sport Apparaus,Textile Machined,Skateboard,Skates
