Dark Gray Silicon Nitride Ceramic Slotted Bushing: High-Elasticity, High-Temperature Precision Positioning Component

Dark Gray Silicon Nitride Ceramic Slotted Bushing: High-Elasticity, High-Temperature Precision Positioning Component

Product Introduction
This product is manufactured from high-purity silicon nitride ceramic material, featuring a dark gray matte texture with a mirror-smooth surface achieved through precision polishing. Designed in a cylindrical structure, it innovatively incorporates a vertically through narrow slot at the top, forming a unique elastic structure. Leveraging the high strength, high elastic modulus, and excellent heat resistance of silicon nitride material, along with precision machining to ensure consistent slot dimensions, it provides reliable elastic positioning and cushioning solutions for high-precision equipment.

Core Advantages
• Exceptional Elastic Design: Slot structure provides uniform elastic deformation with a rebound rate of up to 95%
• Ultra-High Mechanical Performance: Compressive strength ≥2200 MPa, flexural strength ≥750 MPa
• Excellent Temperature Resistance: Long-term use temperature 1200°C, short-term up to 1450°C
• Extremely Low Thermal Expansion: Thermal expansion coefficient 3.2×10⁻⁶/°C, ensuring dimensional stability at high temperatures
• Outstanding Wear Resistance: Hardness HRA 90-92, wear rate below 8×10⁻⁷ mm³/N·m
