Product Description
Silicon Carbide - Stainless Steel Thrust Disc
The Silicon Carbide-Stainless Steel Thrust Disc is a high-performance component designed for face sealing and axial positioning applications. Its advanced composite structure combines a wear-resistant Silicon Carbide face with a high-strength Stainless Steel substrate, delivering exceptional wear resistance and structural integrity in demanding operating conditions.
Material and Properties
Face Material: Pressureless Sintered Silicon Carbide
- Extreme Hardness & Wear Resistance: Second only to diamond and CBN in hardness, providing excellent resistance to abrasive media and erosion.
- Excellent Chemical Inertness: Resists corrosion from strong acids, alkalis, and oxidizers, outperforming most metallic materials.
- High Thermal Conductivity: Rapidly dissipates frictional heat, preventing localized overheating and ensuring operational stability.
- Low Friction Coefficient: Performs exceptionally well against counterparts like carbon and ceramics, reducing starting and running torque.
Substrate/Backing: Stainless Steel
- Outstanding Mechanical Strength: Provides robust structural support, capable of withstanding high axial loads and installation stresses.
- Good Toughness: Prevents brittle fracture of the component during assembly and under pressure shock.
- General Corrosion Resistance: The stainless steel substrate (typically 304 or 316) offers fundamental rust and corrosion protection.
Composite Advantage: This combination leverages the strengths of both materials: Silicon Carbide handles the harsh frictional and chemical environment, while the Stainless Steel ensures structural integrity and ease of installation, achieving optimal performance.
Working Principle
The thrust disc serves two primary functions in equipment: Axial Load Bearing and Face Sealing.
- Axial Load Bearing: As a core component in thrust bearings, it carries and transmits axial loads while limiting shaft movement.
- Face Sealing: In mechanical seals, it forms a friction pair with another smooth face to prevent medium leakage and achieve dynamic sealing.
- Synergistic Operation: The SiC face maintains minimal wear and stable sealing performance, while the stainless steel substrate prevents deformation and ensures even pressure distribution.
