Alumina Sleeve – Superior Durability for Precision Applications

Alumina (al2o3) is an extremely durable technical ceramic. Produced from bauxite ore, alumina serves as the raw material for numerous advanced ceramic applications.

Bushings, sleeves and shafts made of alumina boast high wear resistance with reduced friction to meet the demands of industrial machinery used in chemical, hydraulic, and power generation industries.

Superior Durability

Alumina (Al2O3) is one of the hardest engineered ceramics, capable of withstanding even the most demanding industrial applications without cracking under pressure. Aside from being corrosion resistant and thermal conductive, Alumina offers high strength and stiffness as additional advantages.

Zirconia Toughened Alumina (ZTA) is an advanced ceramic material developed using slip casting techniques that combines the superior properties of both alumina and zirconia grains for outstanding hardness, wear resistance, fracture toughness, chemical inertness and microstructural synergy between grains – combined with careful management of pore distribution and size management – to produce outstanding hardness, wear resistance, fracture toughness and chemical inertness properties in one package. ZTA was specifically created for tough and demanding applications in mind;

Ceramic bushing insulators are essential to many electrical applications, ensuring smooth performance while reducing maintenance costs. Their abrasion resistant properties reduce downtime caused by frequent component replacement and come in a wide variety of shapes and sizes for convenient selection.

High Stiffness

Alumina (Al2O3) is an all-purpose technical ceramic with excellent mechanical properties such as hardness, wear resistance and low erosion levels. Furthermore, its electrical insulation and thermal conductivity properties make it highly sought-after.

Zirconia Toughened Alumina (ZTA) slip-cast ceramic is an innovative ceramic composite material with superior mechanical strength, toughness and corrosion resistance. Its microstructure features an alliance between alumina and zirconia grains; each providing distinct advantages – for instance alumina provides solid structural backbone with high hardness and toughness while dispersed zirconia adds fracture toughness resistance against crack propagation.

Ceramic rods, sleeves and bushings are indispensable components in numerous industrial applications, providing long-term durability, reliability and performance in harsh operating environments. Zirconia ceramic sealing rings, high temperature resistant insulating ceramic gaskets and wear-resistant mechanical shaft sleeves are essential in many petrochemical, manufacturing, aerospace and power industries due to their advanced materials as well as high temperature stability; additionally protecting sensitive electronic devices from vibrational impacts or temperature shocks is another major benefit.

Low Friction

Alumina ceramic insulators are used in motors and other electrical equipment to protect components against shock and wear, providing insulation between components while avoiding shock or wear. Furthermore, these insulators can withstand high temperatures as well as harsh environmental conditions.

Alumina, a naturally occurring crystalline substance found throughout nature, can be extracted from its source through various processes. Bauxite serves as its main source, while being refined using the Bayer process into various grades of activated, smelter-grade, and calcined alumina powders and granular forms.

Alumina ceramic bushings, sleeves, and shafts play an essential role in various industrial applications, providing low friction and superior wear resistance that helps industries achieve efficiency and longevity in their operations. Zirconia-toughened alumina (ZTA), an advanced technical ceramic that boasts superior wear resistance as well as chemical stability and thermal shock resistance, is another key component. ZTA exhibits an integrated composite structure consisting of alumina grains as structural backbone with dispersed zirconia grains providing toughness against crack propagation.

High Temperature Resistance

Alumina ceramic provides superior high temperature resistance and insulation properties, and can withstand operating at temperatures reaching 1200 deg C without oil lubrication.

Steel has excellent corrosion resistance and can withstand acids, alkalis and chemical solvents without being affected. Furthermore, it resists abrasion and impact damage making it an ideal material for industrial uses.

Alumina ceramic tubes are easy to maintain with washing solution, as their surfaces do not attract dust particles or melt during an emergency situation. Furthermore, their fire resistance makes them highly reliable.

Alumina ceramic parts can be machined prior to sintering using standard metalworking equipment in their green body state, providing greater tolerances than post sintering operations. A variety of molding methods are available for producing these ceramic parts including dry pressing, injection, cold isostatic pressing and hot pressing; roller and tunnel kilns are commonly employed for wear-resistant sintering operations.
