Overview
The SKF 5308AH/C3 is a double-row angular contact ball bearing featuring solid inner and outer rings. The 5308AH/C3 SKF is a double-row angular contact ball bearing with solid inner- and outer rings. The design of this bearing type resembles two single-row angular contact ball bearings in O-arrangement but is slightly narrower. This configuration enables efficient load distribution and is ideal for applications requiring reliable performance under combined radial and axial loading.
Key Features
- High Load Capacity: Double-row angular contact ball bearings can support high radial forces and axial forces in both directions.
- Dual-Direction Axial Support: Handles axial loads in both directions simultaneously, reducing the need for multiple bearing types in a single application.
- Compact Design: Narrower profile compared to equivalent single-row configurations, facilitating space-constrained installations.
- Contact Angle: 25° contact angle optimized for radial and moderate axial load balance.
- C3 Internal Clearance: Enhanced clearance class suitable for high-speed applications and thermal stability.
- Chrome Steel Construction: Durable bearing material ensures extended service life and corrosion resistance.
