What Are Self-Aligning Roller Bearings?
FAG self-aligning roller bearings — also known as spherical roller bearings — have two rows of symmetrical rollers and a common sphered outer ring raceway. This unique design allows them to self-align, meaning they can compensate for misalignment between the shaft and housing without reducing performance.
This feature is critical in industries where precise alignment is difficult due to heavy vibrations, shaft deflection, or structural shifts.

Why FAG Bearings Are the Best Choice for Heavy-Duty Applications
1. Superior Load Resistance
FAG self-aligning roller bearings are built to withstand extreme radial and axial loads, making them ideal for operations with continuous or shock loading.
2. Self-Aligning Functionality
The self-aligning feature helps absorb mounting errors or shaft deflection, which greatly reduces stress on surrounding components and ensures a longer lifespan for both the bearing and the machine.
3. High Precision & Stability
FAG’s precision manufacturing process ensures tight tolerances and superior stability — critical for maintaining performance in high-speed or high-vibration environments.
4. Extended Service Life
With optimized roller profiles and premium lubrication compatibility, these bearings offer longer service intervals, reducing downtime and total cost of ownership.
5. Tailored for Industry Needs
FAG provides multiple variations — including sealed versions (2VSR), brass cage (M-type), and special heat treatment (T41A, H40) — to meet the specific needs of sectors like:
-
Mining & Quarrying
-
Cement Production
-
Steel & Rolling Mills
-
Paper Manufacturing
-
Renewable Energy (Wind Turbines)
Real-World Performance
For example, the FAG 22328-E1-T41D bearing is widely used in vibrating screens in mining operations, where it endures constant shock and motion. Its robust cage design and advanced lubrication channels ensure long-term reliability even under the harshest conditions.
Meanwhile, the FAG 24148-B-K30-C3 is a staple in hot strip mills, offering high load ratings and exceptional resistance to heat and contaminants.
