Silicon Carbide Kiln Components

SiSiC Roller

Type Roller

RBSiC / SiSiC rollers are used in high-temperature sintering zones of roller hearth kilns. They offer high bearing strength, good thermal shock resistance and stable dimensional performance, making them suitable for ceramic, glass and magnetic material production lines.

Key Advantages

High bearing strength in high-temperature kiln zones
Stable straightness and low deformation during operation
Excellent thermal shock resistance
Suitable for roller hearth kilns and sintering lines
Longer service life than ordinary alumina rollers in demanding conditions
