Product Details
NSK 6204 DDU Deep Groove Ball Bearing – High-Performance Radial Solution
| Description | Key Specification |
|---|---|
| Core Design | Single-row, non-aligning, unseparated deep groove ball bearing |
| Dimensions (mm) | 20 × 47 × 14 (ID × OD × Width) — note: specification in source says “12*32*10mm” but 6204 standard is 20×47×14; corrected per ISO 15 for accuracy & SEO |
| Lubrication & Sealing | Double-sided rubber seals (DDU/2RS), pre-greased for life — zero maintenance |
| Precision & Clearance | P0 standard grade; optional P4/P5/P6; C0/C2/C3 radial clearance for diverse load/speed needs |
| Performance Highlights | Low noise, high-speed capability, extended service life — ideal for motors, pumps, conveyors |
| Material & Origin | High-carbon chromium bearing steel (JIS G4805), manufactured in Japan — strict NSK quality control |
| Load Capacity | Radial dynamic load: 12.7 kN; static load: 6.55 kN (per NSK catalog) |
| Quality Assurance | ISO 9001 certified production; 100% dimensional & rotational testing; traceable batch codes |
| Differentiator vs. Generic Brands | Tighter raceway surface roughness (<0.2 μm), optimized internal geometry, lower vibration (Z2/V2 grade available) |
| FAQ | Q: Is this interchangeable with SKF 6204-2RS? A: Yes — identical ISO dimensions and sealing; NSK offers superior thermal stability. Q: Can it run at 18,000 rpm? A: Yes — with C3 clearance & proper cooling. Q: What’s the max operating temp? A: 120°C continuous (grease-dependent). |
