| Description | Core Value |
|---|---|
| Model Range | 51118, 51218, 51318, 51120, 51220, 51320, 51122 — precision-matched for axial load applications |
| Load Type | Pure thrust (one-directional) — optimized for high axial rigidity & minimal radial play |
| Material & Hardness | High-carbon chromium bearing steel (GCr15), hardened to HRC 60–64 — ensures longevity under heavy loads |
| Precision Grades | P0 to P2 — ultra-precision options available for CNC spindles and metrology equipment |
| Vibration Control | Z1V1–Z3V3 certified — critical for low-noise industrial automation and medical devices |
| Lubrication Flexibility | Grease or oil compatible — pre-lubricated for immediate installation; re-lubrication ports supported |
| Dimension Standard | 90×120×22 mm (e.g., 51220) — ISO-compliant, direct replacement for legacy SKF & competitor units |
| Quality Assurance | ISO 9001:2008 certified production + 100% dimensional & noise testing |
| Differentiator | Japan-sourced raw material + China-based precision assembly — 30% faster lead time vs. full-Japan imports, zero compromise on runout or surface finish |
| Typical Use Cases | CNC machine tool bases, vertical pump shafts, automotive steering columns, aerospace ground support jacks |
Engineered for reliability where axial stability matters most — these SKF thrust ball bearings deliver consistent performance across demanding industrial environments. Their non-aligning, separable design enables quick maintenance without full disassembly. All models undergo strict vibration and preload validation before shipment.
