Product Details
Deep Groove Ball Bearings 6300–6312 (SKF-Grade, Japan-Made)
| Description | Key Selling Points |
|---|---|
| Unseparated, single-row radial bearing | Optimized for high-speed rotation & compact OEM integration |
| Bearing steel (GCr15 / SUJ2) | Superior hardness (HRC 60–64), fatigue resistance & longevity |
| Seal options: ZZ / 2RS / Open | 2RS offers full dust/moisture protection; ZZ balances cost & sealing |
| Precision grades: P0, P6, P5, P4 | P5/P4 ideal for precision machinery, CNC spindles & robotics |
| Vibration classes: Z1V1–Z3V3 | Z3V3 certified for ultra-quiet operation in medical & audio equipment |
| Standard sizes: 10×26×8 mm to 60×130×31 mm | Full 6300–6312 series compliant with ISO 15 & JIS B 1512 |
| Origin: Japan (NTN/KOYO/NSK/NACHI licensed production) | Rigorous QC per JIS B 1514 — 100% dimensional & noise testing |
| OEM/ODM support + carton/pallet packaging | Custom labeling, branding & logistics-ready delivery |
| Grease or oil lubrication compatible | Pre-lubricated with SKF LGHP 2 or equivalent — ready-to-install |
| HS Code 8482102000 | Capacity: 1M pcs/month | Fast lead time, export-ready documentation, global compliance |
Engineered for demanding applications: automotive wheel hubs, electric motors, agricultural gearboxes, HVAC blowers, and industrial pumps. Unlike generic imports, these bearings deliver NSK-level consistency, tighter tolerances (±0.005 mm), and lower vibration (<2.5 dB at 1800 rpm). All units undergo 100% dynamic load testing and are traceable via batch code. FAQ: Are these genuine SKF? — No, but they meet or exceed SKF 6300-series specs per ISO/JIS and are widely used as SKFs direct replacement. Can I get samples? — Yes, with DHL express (3–5 days). What’s the minimum order? — As low as 10 pcs for evaluation.
