Product Details
Key Specifications & Advantages of NUTR Series Needle Roller Bearings
| Description | Core Value |
|---|---|
| Model Range | NUTR2052, NUTR25, NUTR2562, NUTR30, NUTR3072 — precision-engineered for compact radial load applications |
| Design | Ringless structure (no outer/inner ring) — saves space, reduces weight, ideal for cam followers & gearboxes |
| Material | High-carbon chromium bearing steel (GCR15 equivalent) — hardened to HRC 58–64 for extended fatigue life |
| Precision & Clearance | Available in P0–P2 accuracy grades and C0/C3/C4 clearances — ensures smooth operation under variable thermal loads |
| Lubrication | Pre-greased or oil-lubricated options — low-maintenance, compatible with standard industrial lubricants |
| Dimensions (e.g., NUTR2052) | 20×52×25 mm — optimized footprint for tight-mounting OEM machinery |
| Applications | Automotive transmissions, agricultural equipment, textile machines, printing presses, and robotics joints |
| Quality Assurance | 100% inspected per ISO 9001; batch traceability; 1M units annual capacity — consistent reliability |
| Differentiation vs. Generic Brands | Superior needle alignment tolerance (±0.005 mm), lower noise (≤38 dB), and 25% higher dynamic load rating than standard equivalents |
| FAQ | Q: Are these interchangeable with SKF HK/NK series? A: Yes — identical dimensions & load ratings; full drop-in replacement with enhanced durability. |
