Key Features of Self-aligning Ball Bearings
- Automatic compensation for shaft misalignment (2-3° adjustment capability)
- Manufactured from high-grade stainless steel (420,440,304/316) for corrosion resistance
- Spherical outer ring raceway for self-aligning properties
- Available in both open and sealed (2RS) configurations
- Primarily designed for radial loads with some axial load capacity
- Reduced vibration and noise compared to standard bearings
- Maintenance-free operation with sealed versions
- Suitable for medium to low-speed applications
- Wide operating temperature range
- Long service life even in demanding conditions
Technical Overview
Structure
Self-aligning ball bearings consist of:
- Outer ring: Features a spherical raceway surface with curvature center coinciding with bearing center
- Inner ring: Contains cylindrical or conical bore for shaft mounting
- Rolling elements: High-quality steel balls that bear radial loads
- Cage: Maintains ball position (steel or synthetic resin construction)
Functional Advantages
- Automatic compensation for shaft/housing misalignment
- Excellent radial load capacity with moderate axial load capability
- Smooth operation with reduced vibration
- Optimal for medium-speed applications
- Corrosion-resistant stainless steel construction
Industrial Applications
CXE Bearing self-aligning ball bearings are ideal for:
- Papermaking machinery: Compensates for shaft deflection in wire, press, and drying sections
- Semiconductor equipment: Provides stable, low-vibration support

- Metallurgy and mining equipment: Withstands harsh operating conditions
- Machine tool manufacturing: Ensures precision in misaligned conditions
- Wind power generation: Handles dynamic loads in turbine systems
- Food processing and packaging: Corrosion-resistant for sanitary environments
Selection Considerations
When choosing self-aligning ball bearings, consider:
- Machine type and operating environment
- Shaft specifications and load requirements
- Magnitude and direction of applied loads
- Required speed capabilities
- Lubrication method and maintenance requirements
- Special environmental conditions (temperature, chemicals, etc.)
CXE's stainless steel self-aligning ball bearings deliver reliable performance in applications where shaft deflection and misalignment are concerns, improving equipment reliability and service life.
