What Are Self-Aligning Roller Bearings?
Self-aligning roller bearings—also known as spherical roller bearings—are designed with two rows of rollers and a common spherical raceway in the outer ring. This design allows the bearings to automatically compensate for shaft misalignment, bending, or deflection, which is especially beneficial in demanding industries such as mining, metallurgy, cement, and construction machinery.
Key Advantages of FAG Self-Aligning Roller Bearings
1. Exceptional Load Capacity
FAG bearings such as the 22328-E1, 22222-E1-K, and 24030-E1-2VSR are known for their ability to support both radial and axial loads, even under shock or vibration. This makes them ideal for heavy-load equipment like crushers, conveyors, and vibrating screens.
2. Automatic Misalignment Compensation
Shaft misalignment is common in heavy-duty machines due to thermal expansion, installation errors, or shaft deflection. FAG self-aligning bearings adapt to misalignment, preventing premature wear and minimizing downtime.
3. Longer Service Life
Thanks to high-quality materials and advanced heat treatment processes, models like 23124-E1A-K-M-C3 and 22320-E1-T41D offer exceptional wear resistance and extended operating life, even in dusty, dirty, or high-temperature conditions.
4. Low Maintenance Costs
The robust design of FAG self-aligning roller bearings means fewer replacements and less maintenance, reducing operating costs over time. Grease-retaining seals and coatings (e.g., Corrotect®) further enhance durability in corrosive environments.
