Features
- extremely durable by high hardness and corrosion resistance
- extremely high surface quality by greater rigidity
- better emergency running characteristics compared to steel ball bearings
- low tare weight, circa 40% lighter than bearings made of rolling bearing steel
- suitable for high-temperature applications
- suitable for dry run
- current-insulating, low thermical conductivity
- non-magnetic
- extremely corrosion resistant
- extremely resistant to chemicals
- suitable for foodstuff-applications
- material: ZRO2 - zirconia (rings, balls), PEEK - polyetheretherketone (cage)
- manufacturers of bearings, such as FAG, KOYO, NSK, SKF, SNR, etc. assign different suffixes for their characteristics, for better orientation take note of the comparison table of bearings (see further information)
