3313 WAC3 NSK Double Row Angular Contact Ball Bearing 65mm x 140mm x 58.7mm
3313 WAC3 NSK Double Row Angular Contact Ball Bearing
The 3313 WAC3 is a precision-engineered double row angular contact ball bearing from NSK, specifically designed to handle combined radial and axial loads simultaneously with exceptional reliability. With generous dimensions of 65mm bore × 140mm outer diameter × 58.7mm width, this bearing delivers superior load capacity and rigidity, making it ideal for heavy-duty industrial applications requiring extended service life and consistent performance.
Design & Functionality
Double row angular contact ball bearings feature two rows of balls with angularly displaced raceways, providing significantly enhanced load capacity and rigidity compared to single row designs. This advanced configuration enables:
- Simultaneous handling of substantial radial and axial loads
- Improved stability, stiffness, and load distribution
- Smooth, quiet operation even under heavy loads
- Excellent durability for demanding industrial applications
- Superior bearing arrangement flexibility for precision mounting
The open bearing design provides flexibility for applications where external lubrication management and maintenance accessibility are preferred.
