Product Description

ZYS wheel bearing 6903 Ceramic Ball Bearing High Precision Full Ceramic ZrO2 Bearing 17x30x7mm Hybrid Ceramic Bearing
Product Description

Full ceramic bearings are used in extreme environments (such as high temperatures, corrosive chemicals, steam and strong vacuum). These cereamic bearings have both the inner and outer rings in addition to the rolling elements manufactured from ceramic material. Like hybrid bearings, the bearing balls in full ceramic bearings are usually made of silicon nitride Si3N4 or zirconia ZrO2. The cage in an full ceramic bearing is usually made of high-performance plastic (such as PEEK or PTFE).

Advantages Of Full Ceramic Bearings:

  • resistant to acid, salt and water, and blood
  • non-magnetic
  • lower friction coefficient 
  • resistant to electricity
  • corrosion-resistant
  • lighter, smoother and stiffer

Applications For Full Ceramic Bearings:

  • MRI equipment
  • vacuum environments
  • semiconductor manufacturing
  • radiotherapy
  • food processing industrie
  • any extreme environment requiring non-corrosive, non-conductive or non-magnetic bearings
