SKF NUP314ECP/C3 single-row cylindrical roller bearing with cage, size 70 x 150 x 35 mm. Open bearing (no seals) with EC optimized internal design and polyamide cage for high rigidity and high radial load capacity. C3 internal clearance for applications with higher operating temperatures, shaft expansion, or tighter fits. NUP design supports axial loads in both directions and is commonly used as a locating bearing to position the shaft axially. Typical applications include gearboxes, pumps, compressors, electric motors, agricultural machinery, and industrial equipment.
