| Description | Core Value |
|---|---|
| 6203, 6902, 6710, 6338, 6204 — globally standardized, cross-compatible with SKF, NTN, NSK, KOYO, NACHI, Timken | |
| Dimension (mm) | 10×26×8 mm — ultra-compact design ideal for space-constrained OEM applications |
| Deep Groove Ball Bearing — optimized for high-speed radial loads + moderate axial loads | |
| High-carbon chromium bearing steel (GCr15 equivalent) — hardened to HRC 60–64 for extended fatigue life | |
| Separability | Unseparated unit — ensures precise alignment, simplified installation & reduced assembly time |
| Radial-dominant with bi-directional axial capability — reliable in dynamic industrial environments | |
| Origin & Quality Control | Manufactured in ISO 9001-certified facilities (Germany, Japan, Sweden); 100% dimensional & noise tested |
| 8482102000 — duty-optimized for global import/export; compliant with EU CE & RoHS | |
| 1,000,000 pcs/month — fast lead times & bulk order scalability without MOQ pressure | |
| Differentiator vs. Generic Brands | Superior raceway surface finish (Ra ≤0.08 μm), tighter ABEC-1 tolerances, and lower vibration (Z2/V2 grade) |
Engineered for demanding applications: electric motors, power tools, conveyors, agricultural gearboxes, HVAC fans, and medical equipment. Each batch undergoes rigorous performance validation — including life testing (L10 ≥15,000 hrs at rated load), thermal stability checks (-30°C to +120°C), and corrosion resistance (salt spray ≥96h).
