Key Specifications & Advantages of SKF 51248 Thrust Ball Bearing
| Description | Core Value |
|---|---|
| Interchangeable with 51238/51240/51244/51248 — ideal for global OEM replacements | |
| Dimensions (mm) | 200 × 340 × 78 — high-load capacity thrust design for axial force transmission |
| Material & Precision | GCr15 bearing steel, P0–P2 precision grades — ultra-low runout & extended service life |
| Lubrication Flexibility | Compatible with grease or oil — adaptable to high-speed or high-temperature environments |
| Vibration Control | Z1V1–Z3V3 graded — ensures smooth operation in precision machinery and CNC equipment |
| Non-Aligning, Separated Design | Enables easy installation/maintenance; ideal for fixed-position thrust applications |
| ISO 9001:2008 certified — consistent quality control from raw material to final inspection | |
| Origin & Branding | Manufactured to TIMKEN-spec standards but fully compatible with SKF mounting dimensions |
| Applications | Hydraulic pumps, vertical motors, crane hooks, machine tool spindles, and automotive transmissions |
| Why Choose Us? | Stock-ready (in stock), OEM/ODM support, and real-time technical consultation — no minimum order |
Engineered for reliability under heavy axial loads, this high-quality thrust ball bearing delivers superior rigidity and minimal friction — outperforming generic alternatives in thermal stability and noise reduction. Unlike budget bearings with inconsistent hardness or surface finish, our 51248 units undergo 100% dimensional and vibration testing. Frequently asked: Is it suitable for high-RPM applications? Yes — optimized cage design and precision-ground raceways ensure stability up to 2,200 rpm (with proper lubrication). Can it replace SKF 51248 directly? Absolutely — identical bore, OD, width, and load ratings per ISO 104. What’s the expected L10 life? Up to 12,000 hours under rated load and optimal conditions.
