Open-Tooth Zirconia Ceramic Sleeve with High Toughness & Anti-Cracking Superior Wear Resistance and High Dimensional Precision

This open-tooth zirconia ceramic sleeve is manufactured from high-purity 3Y-TZP zirconia raw material through precision molding, high-temperature sintering, and CNC precision machining. It features an integrated irregular structure with one-side open groove and bottom tooth protrusions. With high density and exceptional toughness, it eliminates chipping and cracking issues common in ordinary ceramics, serving as wear-resistant, insulating, and limiting ceramic spare parts for precision automated equipment.

Widely used in lithium battery equipment, semiconductor automation fixtures, precision instruments, and micro pumps & valves. Functions as limiting bushing, clamping sleeve, wear-resistant guide sleeve, and insulating spacer for workpiece positioning, guiding, and anti-corrosion isolation.

• High Toughness & Anti-Cracking: Phase transformation toughened zirconia provides significantly higher toughness than alumina, preventing edge chipping at open slots and tooth sections.
• Superior Wear Resistance: Low friction coefficient delivers service life 2-3 times longer than regular ceramic components.
• Excellent Chemical Stability: Resistant to acid, alkali, and corrosive liquids for long-term service in harsh chemical environments.
• High Dimensional Precision: Tolerance of inner/outer diameter, slot and tooth profile controlled within ±0.01mm for perfect fitting during assembly.

• Clean inner and outer surfaces of the sleeve before installation to remove dust and impurities.
• Assemble using special tool pressing instead of hammering to prevent ceramic damage.
• Avoid sharp temperature shock from rapid heating or cooling to reduce cracking risk.

Customization per drawings or samples is available with free sampling service. All products undergo full inspection with test reports before delivery. Return and replacement available for non-human-induced defects. Lifelong technical support provided for model selection and working condition optimization.
