Silicon Carbide Ceramic Sleeve Assembly: Precision Industrial Wear-Resistant Sleeve and Core Rod Solution

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.
