Product Details
NTN Japan-Made High-Precision Cylindrical Roller Bearings (NU356EM & More)
| Description | Key Selling Points |
|---|---|
| Ultra-precise P0–P2 tolerance grades, Z1V1–Z3V3 low-vibration options | Japanese manufacturing consistency meets ISO 9001 & JIS B 1514 standards |
| Bore size: 15–90 mm; OD range: 35–180 mm; e.g., 240×500×95 mm spec | Wide dimensional coverage for OEM retrofit & industrial upgrades |
| High-carbon chromium bearing steel (GCr15 equivalent) | Superior hardness (HRC 60–64), fatigue resistance & extended service life |
| Radial-only load design with separable inner/outer rings | Easy mounting, maintenance & shaft alignment — ideal for gearboxes & motors |
| Lubrication-flexible: compatible with premium grease or circulating oil | Reduces downtime; supports high-speed (up to 4,000 rpm) and heavy-duty cycles |
| Non-aligning cylindrical structure (NU/NJ/NF series) | Precise radial guidance — critical for CNC spindles, pumps & compressors |
| ODM/OEM support + carton/pallet packaging | Custom labeling, branding & bulk logistics — trusted by Tier-1 machinery suppliers |
| Origin: China (manufactured under NTN Japan technical license) | Cost-performance edge vs. full-Japan imports — same specs, faster lead time |
| HS Code 8482500090; production capacity 100,000 pcs/year | Stock-ready availability & scalable supply for global distributors |
| FAQ: Are these interchangeable with SKF NU356? Yes — identical ABEC-1/P0 dimensions & load ratings. Tested per ISO 281. | Verified compatibility data available upon inquiry — request our cross-reference sheet. |
