Alumina Ceramic Rollers are critical components used in roller kilns, ceramic firing lines, glass tempering furnaces, powder metallurgy furnaces, and high-temperature industrial heating equipment.
Made from high-purity 95%-99% Al2O3 alumina, the rollers provide exceptional mechanical strength, high-temperature resistance up to 1650-1700°C, excellent thermal shock performance, and outstanding straightness control.
Our ceramic rollers ensure smooth material handling, uniform heat distribution, and long service life even under harsh thermal cycling environments.
FeaturesHigh Purity Alumina (95-99%)
Guarantees excellent chemical stability and minimal deformation under high temperatures.
Superior High-Temperature Resistance
Working temperature up to 1600-1700°C, suitable for continuous firing kilns.
Excellent Thermal Shock Resistance
Capable of withstanding rapid temperature changes without cracking.
High Mechanical Strength
Ideal for supporting heavy loads during ceramic or glass firing processes.
Perfect Straightness & Dimensional Accuracy
CNC machining ensures straightness ≤ 0.5 mm / 1000 mm.
Long Service Life
Resistant to corrosion, oxidation, and wear in high-temperature atmospheres.
