Product Introduction

High Hardness Cylinder Ceramic Plunger Zirconia Bush Ceramic Shaft

Zirconia ceramic shafts, made from zirconium dioxide (ZrO₂), are engineered for high-performance applications requiring exceptional strength, durability, and thermal stability. These shafts exhibit outstanding mechanical properties, including high fracture toughness (8-10 MPa·m¹/²) and bending strength (≥1,000 MPa), surpassing many metals and ceramics like alumina. Their near-zero thermal expansion and resistance to extreme temperatures (-200°C to +800°C) ensure dimensional stability in fluctuating environments, while chemical inertness allows them to withstand corrosive acids, alkalis, and solvents. Widely used in aerospace, automotive, medical, and industrial sectors, zirconia shafts excel in high-speed bearings, fuel pumps, medical devices, and machinery exposed to harsh conditions, offering reduced friction, wear resistance, and biocompatibility.

Production process

1. Grind and crush the raw materials to be slurry or powder

2. se-different method to making the slurry or powder into semi-finished products

3. Put the semi-finished products into the kiln for dewaxing and sintering;

4. After forming and sintering, Ceramic Sleeves products can also be processed by subsequent CNC precision machining according to the drawing requirements. Then Q/C test.

5. Finally package Ceramic Sleeves by bubble paper or cartons and place it on tray for delivery
