Haute température 609 2RS Full Cerami...
Dimensions: Alésage: 9 mm, Diamètre extérieur: 24 mm, Width: 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.
Capacités de charge: While excellent for its material, note that ceramic has lower load ratings than steel. Dynamic Load (Cr): ~1.8 kN, Static Load (Cor): ~0.9 kN. Its superiority lies in its environmental resistance, not pure load capacity.
