Silicon Carbide-Double Row Angular Contact Bearings

Overview of Silicon Carbide Double Row Angular Contact Bearings

Silicon carbide double row angular contact ball bearings are full ceramic bearings made from SiC (silicon carbide), one of the most advanced technical ceramics available. These bearings are designed to handle complex axial and radial loads simultaneously, while maintaining performance in extreme temperatures and corrosive media.

Material Superiority: Why Silicon Carbide (SiC)

SiC offers a unique combination of mechanical, thermal, and chemical properties, making it ideal for demanding bearing applications:

• Extreme Temperature Tolerance: Withstands continuous operation up to 1000 °C and peak exposures up to 1200 °C without deformation or performance loss.
• Exceptional Corrosion Resistance: Inert to most acids, alkalis, and solvents, including aggressive chemicals and saltwater.
• High Mechanical Strength: Maintains structural integrity under heavy loads and high-speed conditions.
• Superior Hardness and Wear Resistance: Extends bearing service life even in abrasive environments.
• Low Friction Coefficient: Promotes efficient high-speed rotation with minimal heat generation.
• Non-Magnetic and Electrically Insulating: Ideal for sensitive equipment in medical, semiconductor, and aerospace industries.

Advantages of the Double Row Angular Contact Design

The double row configuration enhances load-bearing capacity by distributing forces over two contact points per ball. This allows for better support of axial loads in both directions, increased stiffness, and longer operational lifespan in precision and high-speed applications.

Key Applications

1. High-Temperature Processing Equipment

Used in furnaces, glass manufacturing, and heat treatment systems that operate beyond the limits of metal-based bearings.

2. Chemical and Petrochemical Industries

Performs reliably in reactors, pumps, and mixers exposed to aggressive acids and solvents.

3. Aerospace and Defense

Supports demanding mechanical loads in propulsion systems and control actuators under severe environmental conditions.

4. Medical and Laboratory Equipment

Ensures non-contamination and magnetic neutrality in precision devices and sterilization systems.
