Hollow alumina rollers, as hollow bottom rollers or ceramic roller bodies, can be installed in existing roller hearth kiln systems according to customer specifications and are the best solution for roller hearth kilns.
The hollow alumina roller has the advantages of easy operation, excellent application performance, low consumption, and environmental protection.
Characteristic:
Lightweight: The hollow structure reduces the weight of the roller, which helps reduce equipment load and energy consumption, and also facilitates transportation and installation.
High strength: Although lightweight, the hollow alumina roller is still strong enough to withstand a certain load and pressure, ensuring its stability and reliability at work.
Wear resistance: Aluminum oxide itself has good wear resistance and can resist friction and wear, extending the service life of the roller.
High temperature resistance: Alumina can still maintain stable performance in high temperature environments, so hollow alumina rollers are suitable for high temperature workplaces and are not easily deformed or damaged.
Chemical stability: Alumina has good stability to many chemical substances, is not susceptible to corrosion, and can work stably for a long time in various environments.
Thermal conductivity: Aluminum oxide has good thermal conductivity, which helps to quickly dissipate heat from the friction surface, lower the operating temperature, and improve work efficiency.
Shock absorption performance: The hollow structure gives the roller a certain degree of elasticity, which can absorb shock and vibration and protect equipment and workpieces from damage.
