Product Description
Our thick-wall pressureless sintered silicon carbide (SSiC) roller
is engineered to overcome the limitations of conventional rollers,
which typically feature wall thicknesses of only 6–8mm. Available
in two standardized specifications—40mm OD × 20mm ID and 45mm OD ×
20mm ID—this roller delivers exceptional structural strength,
thermal stability, and wear resistance. Designed for extreme
industrial environments, it ensures reliable performance in
applications such as photovoltaic glass kilns, lithium battery
material sintering furnaces, and ceramic roller kilns.
Key Features & Advantages
Reinforced Structural Integrity: With a wall thickness of 10–12.5mm, the roller provides superior load-bearing capacity and resistance to mechanical stress, high-temperature scouring, and corrosive atmospheres.
Exceptional Thermal & Mechanical Properties: Combines high thermal conductivity (196 W/m·K at 20°C), outstanding thermal shock resistance (>350°C ΔT), and extreme hardness (2350 HV) to ensure longevity under cyclic heating and abrasive conditions.
Optimized Manufacturing Process: Produced via pressureless sintering, the roller achieves near-zero porosity (≈0%) and a dense, uniform microstructure for consistent performance.
Proven Industrial Validation: The 40mm OD variant is mass-produced and widely adopted, while the 45mm OD version is process-optimized and rigorously tested for enhanced durability.
