3310 C3 NSK Double Row Angular Contact Ball Bearing 50mm x 110mm x 44.4mm
The 3310 C3 NSK Double Row Angular Contact Ball Bearing is a robust precision bearing engineered for high-speed applications requiring simultaneous radial and axial load handling. This double row configuration delivers exceptional rigidity and load capacity while maintaining a compact design, making it ideal for demanding industrial environments.
Design & Construction
Angular contact ball bearings feature raceway designs in both the inner and outer rings that are angularly displaced with respect to each other along the bearing axis. This unique geometry enables the bearing to accommodate combined loads—both radial and axial forces acting simultaneously.
The double row design integrates two single row angular contact bearings into one unit, offering:
- Reduced axial space requirement compared to two separate bearings
- Bidirectional axial load capacity
- Enhanced bearing arrangement stiffness
- Ability to accommodate tilting moments
- C3 clearance specification for slightly increased radial clearance, ideal for thermal expansion at elevated speeds and temperatures
