shenxing ceramic high precision solid rod part machined ceramic shaft for rotor

Ceramic rotor is a high-performance rotating component made from advanced ceramic materials (predominantly alumina, zirconia, or silicon nitride). It integrates exceptional wear resistance, corrosion resistance, and high-speed stability, replacing traditional metal rotors in precision and harsh working environments.

 

 

  • Shape: Cylindrical, impeller-shaped, or custom-designed (matching equipment rotation requirements).

 

  • Size Range: Diameter 5–200 mm, length 10–300 mm (micro-rotors for precision devices to large rotors for industrial pumps).

 

  • Precision Tolerance: Dimensional tolerance up to ±0.003 mm, concentricity ≤0.005 mm, ensuring smooth high-speed rotation.

 

  • Surface Finish: Ra ≤ 0.2 μm, with optional coating (e.g., PTFE) for enhanced lubricity in specific applications.



  • Superior Wear & Abrasion Resistance: Mohs hardness 8–9 (depending on material), resisting particle erosion and mechanical friction during long-term rotation.

 

  • Corrosion Immunity: Unaffected by acids, alkalis, saltwater, and chemical media, suitable for marine, chemical, and wastewater treatment equipment.

 

  • High-Speed Stability: Low density (30%–50% lighter than metal) and high rigidity, enabling stable operation at ultra-high speeds (up to 10,000+ rpm) with minimal vibration.

 

  • Temperature Adaptability: Maintains structural integrity from -200℃ to 1200℃ (varies by material), avoiding deformation under extreme temperature fluctuations.

 

  • Non-Magnetic & Insulating: Non-conductive and non-magnetic, suitable for electronic, medical, and aerospace equipment sensitive to electromagnetic interference.
