Hohe Temperatur 609 2RS Vollkeramik...
Abmessungen: Bore: 9 mm, Außendurchmesser: 24 mm, Breite: 7 mm.
Full Material: Silicon Nitride (Si3N4) for all components.
Seals: PEEK cage
Operating Temperature: Withstands continuous operation from -60°C to over 800°C without degrading performance or losing pre-load.
Belastungswerte: While excellent for its material, note that ceramic has lower load ratings than steel. Dynamic Load (Cr): ~1.8 kN, Static Load (Kor): ~0.9 kN. Its superiority lies in its environmental resistance, not pure load capacity.
