Product Description
High Precision Zirconia Ceramic Bushing Wear Resistant Non-magnetic Shaft Sleeve
Zirconia (ZrO₂) ceramic structural parts are advanced precision engineering ceramics manufactured from high-purity zirconia powder with stabilizers such as yttria, through dry pressing, isostatic pressing and high-temperature sintering. Known as “ceramic steel”, zirconia ceramics stand out among structural ceramic materials for their exceptional toughness, ultra-high strength and outstanding wear resistance, widely used for precision structural components under harsh mechanical and thermal working conditions.
Zirconia ceramic shaft sleeves, also known as zirconia bushings, are high-precision structural ceramic parts made of yttria-stabilized zirconia (ZrO₂). Featuring ultra-high toughness, extreme surface hardness and excellent dimensional stability, they are engineered as premium alternatives to metal, plastic and ordinary alumina sleeves. These ceramic sleeves are specially designed for high-speed rotation, high-load friction and corrosive industrial working conditions, delivering long-lasting stability and low-friction operation for precision mechanical equipment.
Exceptional Wear Resistance & Low Friction Performance
With a Vickers hardness over 1200 HV and Mohs hardness reaching 9–10 grade, zirconia material boasts outstanding abrasion resistance. The sleeves can be
processed into a mirror-polished smooth surface with ultra-low roughness, effectively reducing rotational friction, surface scoring and inner bore wear during
continuous high-speed operation. Different from metal sleeves that are prone to abrasion and deformation, zirconia ceramic sleeves maintain stable inner
diameter accuracy for a long time, avoiding shaft jitter and equipment failure caused by component wear.
Super High Fracture Toughness & Impact Resistance
Known as “ceramic steel”, zirconia ceramic solves the brittle defect of traditional ceramics. It features excellent fracture toughness and strong impact resistance,
resisting chipping and cracking under frequent start-stop operation, mechanical vibration and instantaneous impact. With low creep rate and high compressive
strength above 2000 MPa, the sleeve maintains perfect dimensional accuracy and structural stability under long-term high-load working pressure.
Excellent Corrosion & Thermal Stability
Zirconia shaft sleeves exhibit superior chemical inertness against most acids, alkalis, salt solutions and organic solvents. They will not rust, corrode or age
in humid, chemical and harsh industrial environments, far outperforming stainless steel and plastic parts. Meanwhile, the material has low thermal expansion
coefficient and excellent thermal shock resistance, withstanding high-temperature cycles and temperature changes without deformation, ensuring consistent
working performance in extreme temperature conditions.
Reliable Insulation & Non-Magnetic Property
This series of ceramic sleeves features excellent electrical insulation and non-magnetic characteristics, with no magnetic adsorption and no current conduction.
It can effectively isolate circuits, prevent electric leakage and magnetic dust adsorption, perfectly adapting to high-voltage electrical equipment, precision
electronic machinery and lithium battery production equipment that require strict insulation and non-magnetic requirements.
High Precision Custom Machining
Adopting fine sintering and ultra-precision grinding technology, our zirconia shaft sleeves achieve ultra-tight dimensional tolerances and high coaxiality. Smooth
inner and outer circular surfaces ensure precise fitting with matching shafts. Standard and non-custom special sizes, stepped sleeves, flanged sleeves and
special-shaped structural sleeves are all available according to customer drawings, fully meeting diverse precision assembly demands.
Wide Industrial Applications
Widely applied in high-speed spindles, precision automation equipment, chemical pump valves, fluid machinery, medical devices, semiconductor equipment,
new energy battery production lines and corrosion-resistant mechanical systems. It is an ideal wear-resistant and insulating structural component for high-precision
and harsh working condition equipment, effectively reducing equipment maintenance costs and extending the overall service life of mechanical systems.
