Overview
The FAG 6224-C3 is a single-row, open deep groove ball bearing manufactured by FAG (Schaeffler Group). Built to DIN 625-1 and ISO standards, this bearing delivers reliable radial load support and handles axial loads in both directions. The C3 clearance designation provides increased internal radial clearance, making it ideal for high-speed operation and thermal expansion compensation.
Key Features
- Single-row deep groove design supports radial and bi-directional axial loads
- C3 internal clearance allows thermal expansion and high-speed performance up to 3400 RPM
- Sheet steel cage construction for durability and reliability
- Open design requires manual lubrication and periodic reapplication
- Manufactured to DIN 625-1, ISO 281, and Deutsches Institut für Normung standards

Typical Applications
The FAG 6224-C3 is widely used in industrial machinery, electric motors, pumps, conveyor systems, and rotating equipment requiring high-speed, radial load support. The C3 clearance makes it particularly suitable for applications where thermal fluctuations occur, such as high-power rotating machinery, turbines, and heavy-duty industrial compressors. Open-design bearings require properly maintained lubrication systems for optimal performance.
