Product Description

Thick-Wall Pressureless Sintered Silicon Carbide Roller | High-Load Capacity & Thermal Stability

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.

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.
