Full Ceramic Deep Groove Ball Bearing CE6306 Si3N4 PEEK open 30x72x19 mm


The all-ceramic deep groove ball bearing CE-6306-Si3N4-PEEK has ceramic bearing rings and rolling elements. It therefore has outstanding properties and meets even the highest demands, its main dimensions comply with DIN 625-1.


1. extremely durable by high hardness and corrosion resistance

2. extremely high surface quality by greater rigidity

3. better emergency running characteristics compared to steel ball bearings

4. low tare weight, circa 40% lighter than bearings made of rolling bearing steel

5. suitable for dry run

6. current-insulating, low thermical conductivity

7. non-magnetic

8. extremely corrosion resistant

9. extremely resistant to chemicals

10. suitable for foodstuff-applications

11.material: silicon nitride Si3N4 (rings, balls), PEEK - polyetheretherketone (cage)
