99.5% Alumina Ceramic Thrust Washer Shim for General Working Conditions

Introduction of Ceramic Thrust Washer

Our ceramic thrust washers adopt two mainstream high-performance ceramic raw materials: 95%/99.5%/99.7% alumina ceramic and 3Y-TZP zirconia ceramic. Both materials own outstanding mechanical properties. Alumina type balances cost and wear resistance for general working conditions; zirconia ceramic delivers higher toughness and impact resistance for heavy-load working scenes.

Technical Parameters

Application Scenarios

Ceramic thrust washers are designed to handle extreme friction and corrosive environments where traditional metal or plastic bearings fail. They are widely applied in:

• Fluid Handling Systems: Used in magnetic drive pumps, chemical pumps, and submersible water pumps due to their corrosion resistance against harsh acids and alkalis.
• Semiconductor Manufacturing: Providing high-purity, non-contaminating, and non-particle-generating wear surfaces for wafer processing equipment.
• Automotive & Aerospace: Acting as wear-resistant shims and thrust bearings in turbochargers, fuel pumps, and high-temperature rotary joints.
• Industrial Machinery: Ideal for high-speed motors, pneumatic tools, and textile machinery where continuous rotation and low friction are critical.

Core Performance Advantages

• Superior Wear Resistance: Harder than stainless steel (Mohs hardness 9 for Alumina), resulting in minimal wear loss during long-term continuous rotation.
• Low Friction Surface: High-precision polished surfaces reduce rotational resistance and noise, often allowing for operation without additional liquid lubrication.
• Strong Chemical Stability: Completely inert to most acids, alkalis, solvents, and oil corrosion; zero risk of oxidation or rust.
• High Temperature Resistance: Maintains structural integrity and mechanical strength at working temperatures up to 1200°C (for Alumina) without softening or melting.
• Low Thermal Expansion: Excellent dimensional stability prevents jamming or clearance issues caused by thermal expansion during high-speed friction heating.
• Electrical & Magnetic Insulation: Completely non-conductive and non-magnetic, making them perfect for electronic and magnetic pump applications.

FAQ (Ceramic Thrust Washers)

1. Should I choose 99.5% Alumina or Zirconia for my thrust washers?
For most high-speed, high-temperature, and corrosive environments, 99.5% Alumina provides excellent wear resistance and cost-effectiveness. However, if your application involves high impact forces or heavy dynamic loads, Zirconia (3Y-TZP) is recommended due to its superior fracture toughness and impact resistance.

2. Can you achieve precise thickness and flatness tolerances?
Yes. While ceramics shrink during sintering, we use precision double-surface diamond grinding and lapping processes after sintering. We can achieve flatness tolerances of ≤0.005mm and highly polished surface finishes (Ra ≤0.2) to ensure a perfect seal and ultra-low friction.

3. How can I get a quotation for the ceramic shims/washers?
Please kindly send us your CAD drawing (or PDF) with technical requirements, tolerance limits, and demand quantity. If you don't have a drawing, you can courier your existing samples to us. We will evaluate and quote our best price within 24 hours.

4. What is the lead-time for samples and batch orders?
If we have the required molds/sizes in stock, samples are free and ship quickly. For custom sizes requiring new tooling, sample production takes about 18 days. For batch production, the lead time is around 25 days. Please note courier fees for samples are collected at destination.
