Hybrid Silicon Nitride Roller Bearings Have High Speed And Electrically Insulating And Maintenance-Free
Product Overview

Our silicon nitride roller bearings use ceramic rollers combined with steel rings (hybrid type) or full ceramic rings (all-ceramic type), designed for high-reliability rotating equipment under extreme operating conditions.

Key Advantages
  • High-Speed Capability - Low density (3.2 g/cm³) reduces centrifugal force, increasing speed limit by 30%-50% compared to steel bearings
  • High Temperature Resistance - Operating range -200°C to +1200°C (all-ceramic type), no hardness loss at elevated temperatures
  • Electrical Insulation - Prevents electric pitting, ideal for inverter motors, generators, railway traction motors
  • Corrosion Resistance - Resists acids, alkalis, seawater, chemical solvents
  • Low Friction & Self-Lubricating - Reduces heat generation, enables long-term operation with minimal or no lubrication
  • High Rigidity & Low Thermal Expansion - Maintains precision positioning, better thermal stability than bearing steel
