Thick-Wall Pressureless Sintered Silicon Carbide Roller
Description:
This product is a thick-wall pressureless sintered silicon carbide (SiC) roller, designed to exceed conventional wall thickness limits (typically 6–8mm) with two standardized specifications:
- 40mm OD × 20mm ID: Mature, mass-produced, and extensively validated in industrial applications.
- 45mm OD × 20mm ID: Process-optimized for enhanced durability, currently undergoing customer trials with proven reliability.
The thick-wall design (10–12.5mm) significantly improves structural integrity, ensuring sustained load-bearing capacity under severe corrosion, high-temperature scouring, or mechanical wear. Ideal for photovoltaic glass kilns, lithium battery material sintering furnaces, and ceramic roller kilns.
