Self-Aligning Ball Bearings
Automatic Misalignment Compensation for Rotating Shafts
General Information
We offer a complete range of self-aligning ball bearings in both original and compatible versions from major manufacturers such as SKF, FAG, NSK, NTN, and INA. These bearings are specially designed to tolerate shaft misalignment and angular deviations caused by installation errors or shaft deflection during operation.
Self-aligning ball bearings consist of two rows of balls and a common spherical raceway in the outer ring, allowing the inner ring to rotate freely while compensating for angular misalignment. This makes them ideal for applications where accurate alignment of the shaft and housing is difficult or where shaft flexing may occur.
Available in open and sealed variants, with cylindrical or tapered bore options, these bearings offer low friction, long service life, and reduced maintenance. They are commonly used in light to moderate load applications with relatively low operating speeds, especially in environments with high shaft misalignment potential.
Common Applications
- Textile machinery and looms
- Conveyors and belt tensioners
- Fans, blowers, and ventilation units
- Light-duty gearboxes and reducers
- Agricultural and forestry equipment
- Wood processing and paper machinery
- Material handling systems with flexible shaft positions
- Electric motor support where axial alignment is difficult
Key Features
- Two rows of balls and a spherical outer ring raceway for automatic alignment
- Compensates for angular misalignment of up to ±3°
- Available with cylindrical or tapered bores (for adapter sleeves)
- Low friction and quiet operation, even under variable shaft alignment
- Sealed variants (2RS) available for environments with contamination
- High-quality materials: chrome steel, stainless steel for corrosive settings
- Reduced maintenance requirements and extended bearing life
Ordering Support
Our team can help identify the correct self-aligning bearing based on housing geometry, load direction, shaft diameter, and environmental conditions. We assist with cross-referencing part numbers, clearance class selection, and shaft fit verification. Whether you’re an OEM designer or MRO engineer, we offer technical guidance tailored to your application.
Both original and compatible self-aligning ball bearings are available. We do not claim affiliation with trademark owners—names are used solely for identification and compatibility reference.
