SSIC Ceramic Sliding Bearing for Pump Sleeve Thermal Expansion Difference Compensation

Description of Sliding Bearing Sleeve:

Overview

The silicon carbide (SiC) sleeve is precision-engineered from high-purity SiC material, offering exceptional wear resistance, corrosion resistance and high-temperature stability. Widely used in rotating equipment across chemical, mechanical and energy industries, it is particularly suitable for long-term operation under harsh conditions including high speed, strong corrosion and extreme temperatures.

Material Properties

Silicon carbide ceramics exhibit outstanding mechanical properties at room temperature, including high strength, hardness, and elastic modulus. They also demonstrate excellent thermal stability with high thermal conductivity, low thermal expansion coefficient, as well as remarkable specific stiffness and optical machining characteristics.

Key Features

• Superior Wear Resistance: Mohs hardness 9.5, 5-10x lifespan vs metal sleeves
• Excellent Corrosion Resistance: Withstands strong acids/alkalis
• High-Temperature Stability: Maintains performance up to 1650°C
• Low Friction: Precision polished surface 
• Lightweight: 1/3 density of steel reduces operational load

Technical Specifications

Typical Applications

• Mechanical seals for chemical process pumps
• Rotary components in semiconductor equipment
• Bearing assemblies for molten salt pumps
• Specialized nuclear industry equipment
