Product Description

Yttrium-stabilized Zirconia Piston Zirconia Ceramic Plunger High-precision Insulating Wear-resistant High-hardness

Zirconia ceramic plungers are high-performance engineered ceramic precision components, 
manufactured from high-purity zirconia (ZrO₂) raw materials through advanced powder metallurgy processes. 
Ideal for high-pressure hydraulic systems, they deliver unmatched wear resistance under continuous friction and extreme pressure conditions.
 
With a low friction coefficient and high mechanical strength (≥1000Mpa), 
these plungers minimize abrasion even in high-speed, high-load hydraulic circuits. 
They avoid the wear and metal debris generation common with steel plungers, protecting valves and cylinders from damage. 
Their wear resistance ensures consistent pressure output and extends the lifespan of hydraulic systems, 
making them suitable for heavy machinery and industrial hydraulics.
