SKF, a global leader in bearing technology, manufactures a wide range of thrust bearings that are designed to handle axial (thrust) loads — either in one direction (single direction) or both directions (double direction). These bearings are ideal for applications where axial forces are predominant.
🧾 Types of SKF Thrust Bearings
1. Thrust Ball Bearings
Used for: Low-speed applications with light axial loads
Types:
Single Direction (e.g., SKF 51100 series): Handles axial loads in one direction.
Double Direction (e.g., SKF 52200 series): Handles axial loads in both directions.
Features
Can accommodate axial loads only
Not suitable for radial loads
Separatable components
High-quality steel and raceways
2. Cylindrical Roller Thrust Bearings
Used for: High axial loads, moderate speeds
Examples: SKF 811 series
Features
High load carrying capacity
Suitable for applications with heavy axial loads
Rigid and space-saving
Can accommodate slight misalignments
3. Spherical Roller Thrust Bearings
Used for: Very high axial loads, combined axial and radial loads
Examples: SKF 29400, 29300 series
Features
Self-aligning capability (can handle misalignment)
Extremely high load capacity
Handles both axial and some radial loads
Ideal for heavy-duty industrial use (gearboxes, turbines, etc.)
4. Tapered Roller Thrust Bearings
Used for: Heavy axial loads, especially in automotive applications
Examples: Customized SKF variants for gearboxes and axles
