In 1984, for the first time in Japan, FYH succeeded in the production of total ceramic bearings from start-to-finish production of raw materials. Since that time, user feedback has confirmed that this series has proven itself as the ultimate choice for a multitude of special operating environments. After more than two decades of continual development, this series has been evaluated as "the most reliable maintenance-free bearing" for any industry, and it has evolved to include a variety of options to satisfy many specifi c needs.
The ceramic balls and precision inner and outer rings of the Ceraball bearing demonstrate excellent wear resistance and provide longevity and stable performance in applications where temperature extremes, high speed, torque, and corrosion are factors.

The Ceraball series exhibits extremely high anti-abrasion qualities and offers remarkably stable performance in the most severe environments.

Ceraball features

Reduced maintenance costs
Re-lubrication intervals can be significantly extended or eliminated altogether.
Green bearings
Excessive grease discharge can be eliminated thereby contributing to a cleaner environment.
Independent operation
Supplementary items such as cooling devices and automatic grease replenishment systems can be eliminated.
Low friction
Low friction operation reduces the amount of energy required thereby saving electricity and money.
High stress resistance
The threat of shattering from foreign matter incursion is greatly reduced which creates a safer working environment.
Non-conductive
Electric arcing is eliminated.

FYH silicon nitride ball production process
  
 
 
       
  FYH has established a superior production process from mixing ingredients to molding, sintering, and processing. Compared with silicon nitride balls produced by other manufacturers, we are proud of the overwhelming high strength of the Ceraball, and we can promise consistently high quality, better product performance, and longer life.

 

 

Maintenance cost reduction example on a heat-treatment furnace
 
Standard unit
Ceraball unit
The standard unit is re-lubricated with high-temperature grease every day and completely changed every six months.
The Ceraball unit operates for two years without re-lubrication.
