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.

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.
