CS Ceramic Ball Bearings | High-Temperature & Corrosion Resistant Bearings | Taiwan Manufacturer
CS manufactures premium ceramic ball bearings made from Silicon Nitride (Si3N4) or Zirconium Oxide (ZrO2) for extreme environments. Our full ceramic bearings offer superior corrosion resistance, high-temperature performance, and electrical insulation for semiconductor, chemical, and pharmaceutical equipment 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.

How can ceramic ball bearings improve semiconductor equipment reliability in high-temperature processes?
Our Silicon Nitride ceramic bearings maintain dimensional stability up to 800°C, significantly outperforming steel bearings in semiconductor wafer processing equipment. This exceptional thermal resistance prevents bearing failure during high-temperature manufacturing processes, eliminates electrical arcing that can damage sensitive components, and extends maintenance intervals. Request specifications to see how our ceramic bearings can reduce downtime in your semiconductor manufacturing line.
Our ceramic ball bearings deliver exceptional performance in extreme operating conditions, making them ideal for semiconductor manufacturing, pharmaceutical equipment, chemical processing, TFT-LCD production, and vacuum applications. With significantly longer service life than steel bearings, our products offer outstanding dimensional stability, low friction in dry-running conditions, and complete resistance to electrical arcing. Chin Sing's ceramic bearings are available in multiple series including 6000, 6200/6300, 6800, 6900, and specialized micro ball bearing configurations to meet diverse industrial requirements across Taiwan and global markets.
