Product Description
Precision Silicon Nitride Ceramic Guide Rail – Lightweight, Electrically Insulating & Built For Extreme Heat
Product Overview
This silicon nitride ceramic I-beam guide rail is manufactured using hot pressing sintering technology, featuring a uniform dark gray matte texture with a precision ground surface. The innovative I-beam symmetrical structure combines an elongated main body with vertical rectangular protrusions at both ends and the middle to form a stable three-support point structure. This design ensures sufficient structural strength while achieving precise guide positioning functionality, making it particularly suitable for high-precision automated equipment applications.
Primary Applications
- High-Temperature Equipment: Heat treatment furnace conveying guide rails, sintering furnace bearing tracks
- Precision Machinery: CNC machine tool linear guide rails, precision measuring instrument guide components
- Automated Equipment: Robotic arm positioning tracks, automated production line conveying guide rails
- Semiconductor Manufacturing: Wafer transfer guide rails, vacuum equipment guide components
- Special Equipment: High-temperature spraying equipment guide rails, laser processing machine guide mechanisms
Product Advantages
- Ultra-high Structural Strength: Compressive strength ≥2400 MPa, flexural strength ≥720 MPa
- Exceptional Wear Resistance: Vickers hardness ≥1580 HV, wear life 8 times longer than alloy guide rails
- Excellent Thermal Stability: Continuous operating temperature -60℃～1380℃
- Low Friction Coefficient: Dynamic friction coefficient ≤0.15, no additional lubrication required
- Precise Dimensional Stability: Thermal expansion coefficient 3.1*10⁻⁶/℃, ensuring high-temperature accuracy
