FAQ: Is this bearing interchangeable with SKF NU2352 or FAG N2352? Yes — identical boundary dimensions and load ratings per ISO 281. NTN’s P5 grade exceeds SKF’s standard P6 in radial runout control. What’s the max speed at 50°C ambient? Up to 1,850 rpm (oil-lubricated, P5 grade). Can it handle shock loads? Yes — hardened raceways + optimized roller profile reduce edge stress by 22% vs. generic imports.
