Zirconia-Double Row Angular Contact Bearings

What Are Zirconia Double Row Angular Contact Bearings?

Zirconia double row angular contact bearings are a type of full ceramic bearing constructed entirely from zirconium dioxide (ZrO₂). They feature two rows of ceramic balls arranged in an angular contact configuration, allowing them to handle both radial and axial loads in multiple directions. This design increases load capacity and stiffness compared to single row designs, making them ideal for complex mechanical systems.

Key Benefits

• High Temperature Resistance: Withstands operating temperatures up to 400 °C (752 °F) without loss of structural integrity.
• Excellent Corrosion Resistance: Performs reliably in acidic, alkaline, or salt-rich environments.
• Non-Magnetic & Non-Conductive: Suitable for use in magnetic-sensitive equipment and electronic applications requiring insulation.
• Enhanced Load Capacity: The double row configuration allows for higher radial and axial load support.
• Stable in Extreme Environments: Resilient under conditions involving temperature fluctuations, aggressive chemicals, or exposure to moisture.

Material Advantages: Zirconium Dioxide (ZrO₂)

Zirconia is a premium ceramic material valued for its high hardness, low friction coefficient, and resistance to wear and corrosion. It is often used in applications where both mechanical durability and chemical stability are essential.

Common Applications

1. Chemical Processing Equipment

Used in pumps, agitators, and reactors where exposure to corrosive fluids is unavoidable.

2. High-Temperature Furnaces and Kilns

Provides stable performance in machinery operating under extreme heat conditions.

3. Medical and Diagnostic Devices

Ideal for MRI machines and non-magnetic systems where cleanliness and chemical compatibility are essential.

4. Precision Machinery and Robotics

Used in cleanroom automation and robotic arms where high stiffness, corrosion resistance, and electrical insulation are required.
