Open-Tooth Zirconia Ceramic Sleeve | Special Grooved Zirconia Ceramic Bushing
Product Introduction
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.
Application
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.
Core Advantages
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.

Instructions for Use
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.
After-sales Service
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.
Frequently Asked Questions
Q: What advantages does zirconia sleeve have over alumina sleeve?
A: Zirconia provides better toughness, ensuring thin-walled open slots and teeth are less prone to chipping off. It offers superior wear and impact resistance for high-frequency reciprocating operations.
Q: Can I customize opening width and bottom tooth shape?
A: Yes, opening size, tooth quantity, and wall thickness can be customized with new mold development to meet specific application requirements.
