Overview
The SKF 5309AH/C3 is a precision double row angular contact ball bearing engineered for demanding industrial machinery. Unlike single-row bearings, this design combines two rows in an O-arrangement, distributing loads across both radial and axial directions. The bearing features solid inner and outer rings with an open fillet radius closure and C3 internal clearance, making it ideal for applications requiring high load capacity and moderate speed operation.
Key Features
- Double Row Angular Contact Design: Resembles two single-row angular contact ball bearings in O-arrangement but is slightly narrower, delivering superior load distribution
- Bidirectional Load Support: Can support high radial forces and axial forces in both directions
- 30° Contact Angle: Optimized for combined radial-axial loads common in spindles, gearboxes, and precision machinery
- Open Fillet Radius Design: Allows better grease retention and reduced friction at moderate speeds
- Steel Cage Construction: Durable, cost-effective cage material rated for industrial environments
