3208 B-2RSRTNG NSK Double Row Angular Contact Ball Bearing 40mm x 80mm x 30.2mm
The 3208 B-2RSRTNG NSK Double Row Angular Contact Ball Bearing is a precision engineered bearing designed to handle combined radial and axial loads simultaneously, making it an excellent choice for high-speed applications requiring reliable performance and extended service life.
Design & Functionality
Double row angular contact ball bearings feature two rows of balls with angularly displaced raceways, providing enhanced load capacity and rigidity compared to single row designs. This configuration enables:
- Simultaneous handling of radial and axial loads
- Improved stability and load distribution
- Smooth, quiet operation at high speeds
- Excellent durability for demanding industrial applications
- Low axial clearance in O- and X-arrangement configurations for precision mounting
The 2RS sealed design incorporates lip seals on both sides, providing effective protection against contamination and dust ingress while helping to retain lubrication for extended bearing life and reduced maintenance requirements.
