Key Specifications & Benefits of SKF 61944 Deep Groove Ball Bearing
| Description | Value / Benefit |
|---|---|
| Model & Precision Grade | SKF 61944 — ISO P5 high-precision grade, ultra-low vibration & noise |
| Dimensions (mm) | 220 × 300 × 38 — optimized for heavy radial loads in compact spaces |
| Bearing Steel | High-carbon chromium steel (100Cr6), vacuum-melted & hardened for >2× service life |
| Load Capacity | Dynamic load: 325 kN | Static load: 370 kN — ideal for continuous industrial operation |
| Contact Angle | 0° — pure radial support with minimal axial play and superior rigidity |
| Sealing & Lubrication | Open design — compatible with high-temp greases (e.g., SKF LGHP 2) or oil bath systems |
| Origin & Traceability | Manufactured in Japan under strict SKF QMS — full batch traceability & RoHS compliance |
| Differentiator vs. Generic Brands | Micro-ground raceways + super-finished balls reduce friction by 18% and extend L10 life by 2.3× (per SKF Life Model) |
| Typical Applications | Wind turbine gearboxes, mining conveyor drives, large HVAC fans, marine propulsion systems |
| FAQ: Can it replace older 61944 units? | Yes — fully interchangeable per ISO 15; enhanced fatigue resistance ensures longer uptime without retrofitting |
