Ceramic Ball Bearing | Precision Bearing Sleeves, Lock Nuts & OEM Parts Supplier | Chin Sing Taiwan
Full ceramic ball bearings constructed entirely of ceramic material. Inner / outer races and balls are made of Silicon Nitride (Si3N4) or Zirconium Oxide (ZrO2). They are available as full complement (no cage) or with a cage made from PEEK or PTFE. Full ceramic bearings are for medium load and medium speed applications. It is not possible to achieve the inner and outer ring roundness that is found with precision steel bearings, so full ceramic bearings have lower speed ratings. Browse Chin Sing Precision's high-quality bearing sleeves, adapter sleeves, bushings, wear plates & more. Expert Taiwanese manufacturer providing custom & standard solutions for demanding applications.
Ceramic Ball Bearing
Full ceramic ball bearings constructed entirely of ceramic material. Inner / outer races and balls are made of Silicon Nitride (Si3N4) or Zirconium Oxide (ZrO2). They are available as full complement (no cage) or with a cage made from PEEK or PTFE. Full ceramic bearings are for medium load and medium speed applications. It is not possible to achieve the inner and outer ring roundness that is found with precision steel bearings, so full ceramic bearings have lower speed ratings.
Because it can be used in extreme badly environment and special situation, it applies to aviation, seafaring, petroleum, chemical industry, automobile, electronic equipment, metallurgy, electric power, textile, medical device, vacuum equipment and military affairs field.
Material
Inner / outer races => ZrO2, Si3N4
Balls => ZrO2, Si3N4, Glass
Cage => PEEK, PTFE, Bakelite, Nylon, Full complement (no cage)
Features List
- High temperature resistance, corrosion resistance, anti-magnetic, electrical insulation, vacuum, light specific gravity, lubrication-free (Sl3N4 3.2g/cm³) (ZrO2 6.2g/cm³) (bearing steel 7.85g/cm³).
- Higher hardness and better elasticity compare to standard steel bearings.
- Full ceramic bearings can be run completely dry.
- Excellent corrosion resistance allows them to run in concentrated acids, alkalis or submerged in seawater without corroding.
- More suitable for temperature variation.
- The life cycle of full ceramic bearings are much longer than steel bearings.
- Prevent electrical arcing. The natural insulating properties of ceramic material eliminate this type of damage.
