Overview
SKF 5308 A-2Z/C3 is a double-row angular contact ball bearing featuring solid inner and outer rings. This bearing type resembles two single-row angular contact ball bearings in O-arrangement but is slightly narrower. The A-2Z designation indicates double metal shields on both sides, providing contamination protection without affecting high-speed operation.
Key Features
- Double-row angular contact design — supports high radial and axial loads in both directions
- 40 mm bore diameter, 90 mm outer diameter — compact footprint for space-constrained installations
- C3 internal clearance — optimized for preloaded or high-temperature operating conditions
- Metal shields (2Z) — contamination protection ideal for industrial environments
- 30° contact angle — balanced radial and axial load capacity
- New in box condition — ready for immediate installation
Technical Specifications
Double-row angular contact ball bearings can support high radial forces and axial forces in both directions. The greater the contact angle, the greater the axial load capacity of the bearing.
Typical Applications
- Machine tool spindles and headstocks
- Industrial gearboxes and power transmission
- High-speed rotating machinery
- Pump and compressor assemblies
- Automotive and agricultural equipment
- General industrial automation systems
