The outer and inner ring of the Hybrid Ceramic Bearing is made from special steel, including high carbon chromium bearings steel. Cage can be made of metallic material, resin or composite material depending on the intended operating conditions of the bearing.

Features
• Ceramic Silicon Nitride (Si3N4) Roller
• Suitable for high speeds
• provide maximum resistance against the passage of electric current
•less friction
•less heat
•Increased maintenance intervals due to longer rating life of the grease

Applications
Electric motors, especially traction motors, and in applications running under severe operating conditions
