Product Description
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
Product Configurations
| Type | Roller | Ring | Application |
|---|---|---|---|
| Hybrid Ceramic Bearing | Si₃N₄ Roller | Steel (GCr15) | High speed, electrical insulation, moderate load |
| All-Ceramic Bearing | Si₃N₄ Roller | Si₃N₄ Ring | High temperature, strong corrosion, non-magnetic environment |
Available Bearing Types
- Silicon nitride cylindrical roller bearings
- Silicon nitride tapered roller bearings
- Silicon nitride spherical roller bearings
- Custom dimensions and precision grades (P0 / P6 / P5 / P4)
Typical Applications
- High-speed spindles (machine tools, PCB drilling machines)
- EV drive motors
- Aero-engine accessory drives
- Chemical pumps, vacuum pumps, semiconductor equipment
- Wind turbine gearboxes
- Medical equipment (e.g., CT scanner high-speed rotating parts)
