Overview
The SKF 6224/C3 is a single-row deep groove ball bearing designed for applications requiring higher rotational speeds and moderate temperature variations. This bearing has an inner diameter of 120 mm, an outer diameter of 215 mm and a thickness of 40 mm. The suffix “C3” means that the bearing has increased internal clearance, and will require a higher operating temperature, or a higher rotation speed.
Key Features
- Open-type design with no seals or shields
- Increased internal clearance (C3) optimized for high-speed operation
- Hardened steel balls and raceways, ensuring optimal load distribution and reduced friction
- Low friction and optimized for low noise and low vibration; accommodates radial and axial loads in both directions
- Standard precision manufacturing
Technical Specifications
The bearing’s dimensions are 120x215x40 with a cylindrical bore. Standard cage type, no external modifications, and no coating. Designed for high-speed applications in machinery requiring reliability and efficient rotation.
Typical Applications
- Electric motors and gearboxes
- Pumps and compressors
- Industrial machinery spindles
- Automotive and aerospace rotating equipment
- Manufacturing equipment requiring high-speed, low-vibration operation
