Precision Engineering Our Zirconia Ceramics Are Precisely Machined To Meet The Highest Standards Of Accuracy And Precision

Product Introduction

This product is a high-performance cylindrical component machined from yttria-stabilized zirconia (YTZP) ceramic. It features a distinct design with a central cylindrical body, an integral boss for precise positioning, a through hole, and optional side holes. Engineered to excel in extreme industrial environments, this component leverages zirconia's exceptional physical and chemical properties. Its superior hardness, exceptional wear resistance, and excellent corrosion resistance make it a critical element for enhancing equipment reliability and service life.

Primary Applications

This component is widely used in precision industries demanding high wear resistance, corrosion resistance, and thermal stability:

• Mechanical Seals: Used as seal rings or seats in pumps, compressors, and reactors for reliable rotary shaft sealing.

• Bearings and Balls: Ideal for ball bearings, cages, or sleeves, especially in unlubricated or corrosive media.

• Fluid Handling Systems: Serves as valve cores, plungers for metering pumps, or wetted parts for abrasive slurries and chemicals.

• Automation Equipment: Functions as high-precision guides, fixtures, and wear-resistant bushings.

Key Advantages

• Exceptional Wear Resistance: High hardness (HRA ≥88) provides a service life multiples longer than metal equivalents.

• Superior Corrosion Resistance: Resists erosion from most acids, alkalis, and salts.

• High Strength & Toughness: Transformation toughening grants very high flexural strength and fracture toughness.

• Low Friction Coefficient: Ensures smooth operation, reducing power loss and stick-slip.

• High-Temperature Stability: Can operate continuously at temperatures up to 800°C with low thermal expansion.

• Electrical Insulation: Excellent insulator, suitable for specialized electrical applications.

Specifications Table

Manufacturing Process

Raw Material Preparation (High-Purity Zirconia Powder) → Isostatic Pressing/Injection Molding → Precision Machining (Turning, Grinding, Boring, Drilling) → High-Temperature Sintering (>1500°C) → Fine Grinding/Polishing → Non-Destructive Testing (Dimensional, Visual, Crack Detection) → Packaging.

Usage Instructions

1. Installation: Use non-metallic tools (e.g., copper hammer, nylon rod) to avoid impact damage or chipping.

2. Fitting: When assembling with metal parts, allow for appropriate thermal expansion clearance and ensure mating surfaces are clean.

3. Avoid Impact: Despite its toughness, zirconia is a brittle material. Avoid sharp point impacts or excessive radial shock loads.

After-Sales Service

We provide comprehensive technical support and after-sales service, including product consultation, custom sizing, and installation guidance. A 12-month warranty against manufacturing defects is provided.

Frequently Asked Questions (FAQ)

• Q: Can this part be customized?

  • A: Yes. We support custom manufacturing based on your drawings, including specific bore/OD dimensions, boss location, and side hole angles.

• Q: What is the difference between Zirconia and Alumina Ceramic?

  • A: Zirconia offers significantly higher strength and toughness than alumina, making it more impact-resistant but also more costly. Alumina is harder but more brittle.

• Q: Can the side holes be threaded?

  • A: Yes, but threads in ceramic are relatively fragile. They are recommended for connecting non-metal tubing or as guide holes, not for high-torque applications.
