The Zirconia Hollow Sleeve is a high-toughness alternative to traditional alumina sleeves, specifically engineered for high-impact and high-stress environments. Known for its metal-like thermal expansion, it can be shrink-fitted or press-fitted into steel housings without the risk of cracking common in other ceramics. The hollow core is finished to a mirror-like smoothness, providing a perfect guiding surface for plungers or shafts with minimal friction and zero particle shedding. These sleeves are ideal for pharmaceutical, chemical, and precision engineering applications where reliability and clean-room performance are non-negotiable.
Key Features:
"Ceramic Steel" Toughness: Highest resistance to crack propagation among all oxide ceramics.
Tight Tolerance Matching: Achieves sub-micron precision for perfect integration with rotating or reciprocating shafts.
Corrosion & Erosion Proof: Maintains internal surface integrity even when handling abrasive or corrosive fluids.
Thermal Compatibility: Expands and contracts similarly to steel, ensuring stability in fluctuating temperatures.
