Product Introduction
The silicon carbide ceramic sleeve assembly is a high-performance industrial component consisting of a high-precision silicon carbide ceramic sleeve and a matching core rod. The sleeve features a unique multi-hole distribution design with uniformly arranged circular holes on the end face and a precision through shaft hole at the center. The assembly is made of reaction-bonded silicon carbide material, presenting a dark gray matte texture with a uniform and dense microstructure. This special design ensures both the structural strength of the component and provides optimized channels for fluid passage and heat exchange.
Main Applications
High-temperature pump and valve mechanical seal systems
Corrosion-resistant bushings for chemical equipment
Semiconductor wafer handling rollers
Photovoltaic silicon wafer sintering fixtures
Wear-resistant bearing bushings for machinery
Transmission components for high-temperature furnaces
Guide components for precision instruments
Automotive water pump mechanical seals
Product Advantages
Exceptional Wear Resistance: Hardness up to 2800HV, wear resistance is 10 times that of steel
