Black Stepped Silicon Carbide Ceramic Sleeve: High-Strength Wear-Resistant Dual-Layer Cylindrical Component

Black Stepped Silicon Carbide Ceramic Sleeve: High-Strength Wear-Resistant Dual-Layer Cylindrical Component

Product Introduction
This product is a black stepped cylindrical structural component made using reaction-bonded silicon carbide. It features a unique double-layer stepped design with a mirror-finish surface achieved through precision grinding, and maintains extremely high concentricity in its central through-hole. The product fully utilizes the excellent high-temperature stability and wear resistance of silicon carbide material, achieving excellent mechanical sealing and guiding accuracy through rational structural design. Its balanced physical properties and outstanding chemical stability make it an ideal choice for high-speed and high-pressure operating conditions.

Core Advantages
• Exceptional Wear Resistance: Hardness up to HRA 92-94, wear resistance 5-8 times that of bearing steel
• Excellent Temperature Resistance: Maintains stable performance in high-temperature environments up to 1380°C
• Ultra-High Mechanical Strength: Compressive strength ≥2000 MPa, flexural strength ≥380 MPa
• Low Friction Coefficient: Friction coefficient ≤0.15, with self-lubricating properties
• Outstanding Chemical Stability: Resistant to acid and alkali corrosion, with excellent oxidation resistance
