Product Description
Silica Ceramic Roller is made of high-purity silica ceramic, which is resistant to high temperature and wear. It is used for supporting and transporting materials in industrial furnaces and high-temperature conveying systems.
Features
High-temperature resistance
Made from high-purity silicon, the sintered material boasts a dense microcrystalline structure, ensuring stable shape even at high temperatures.
Wear resistance
The surface undergoes precision polishing and high-temperature sintering, resulting in high friction resistance. It maintains a smooth surface even during long periods of continuous conveying of heavy workpieces.
High dimensional accuracy
Utilizing advanced ceramic molding technology and precision grinding processes, dimensional tolerances are controlled within ±0.05mm, ensuring a stable and reliable rolling process.
Customization range
Dimensions: Diameter, width, bore size, cylindrical, or other special shapes.
Material: Adjustable silica purity and ceramic formulation.
Surface treatment: Polishing, sandblasting, coating, etc.
Structural design: Single roller, bearing combination, or multi-section assembly.
