Key Specifications & Benefits of NTN NU332EM Cylindrical Roller Bearings
| Feature | Detail |
| Model Range | NU330EM, NJ330EM, N330EM, NU332EM — precision-matched interchangeable series |
| Bore & OD Sizes | 15–90 mm bore / 35–180 mm outer diameter — wide fit flexibility for OEM machinery |
| Material & Hardness | High-carbon chromium bearing steel (JIS SUJ2), hardened to HRC 60–64 for extended fatigue life |
| Load Capacity | Ultra-high radial load rating — ideal for heavy-duty industrial gearboxes and motors |
| Precision Grade | Available in P0, P6, P5, P4, P2 — P5/P4 grades meet strict CNC spindle requirements |
| Vibration Control | Z2V2/Z3V3 certified — low-noise operation critical for textile, paper, and packaging lines |
| Lubrication Options | Pre-greased (NLGI #2) or oil-lubricated — compatible with SKF LGMT 2 & ISO VG 32/68 oils |
| Origin & Traceability | 100% Japan-made (NTN Hamamatsu Plant), full batch traceability & mill test reports |
| OEM/ODM Support | Custom cages (brass/polyamide), special clearances (C3/C4), laser marking & packaging |
| Why Choose NTN vs. Generic? | ±0.5 μm raceway roughness (vs. ±2.5 μm typical), 3× longer L10 life under identical loads |
Engineered for reliability in high-speed, high-load applications — from steel mill roll stands to wind turbine gearboxes. Every NU332EM bearing undergoes 100% dynamic testing, dimensional verification, and vibration screening per JIS B 1514-1. Backed by NTN’s global warranty and technical support network.
