Key Specifications & Advantages of SKF Thrust Ball Bearings (51118–51320)
| Description | Core Value |
|---|---|
| Models | 51118, 51218, 51318, 51120, 51220, 51320, 51122 — wide selection for axial load optimization |
| Dimensions (e.g., 51120) | 90×120×22 mm — precision-machined for tight-fit OEM integration |
| Precision Grades | P0 to P2 — ultra-high accuracy for high-speed & low-vibration applications |
| Vibration Levels | Z1V1 to Z3V3 certified — ideal for noise-sensitive machinery |
| Lubrication Flexibility | Grease or oil compatible — adaptable to diverse operating environments |
| Material & Build | High-purity bearing steel — superior hardness, fatigue resistance & longevity |
| Load Direction | Single-direction thrust only — optimized for pure axial loads (no radial) |
| Certification | ISO 9001:2008 — consistent quality control from raw material to packaging |
| OEM/ODM Support | Custom branding, packaging & specs — trusted by global industrial partners |
| In-Stock Availability | Ready-to-ship inventory — fast lead times, no production delays |
Applications: Hydraulic pumps, automotive transmissions, machine tool spindles, crane rotators, and vertical shaft systems requiring high axial rigidity.
Why SKF? Unlike generic thrust bearings, these feature tighter raceway geometry tolerances, lower contact stress, and superior surface finish — delivering up to 30% longer service life under identical loads. All units are 100% tested for rotation torque and axial play pre-shipment.
FAQ: Q: Are these genuine SKF-branded? A: Yes — manufactured in Japan under SKF licensing & quality oversight. Q: Can they handle shock loads? A: Optimized for steady axial loads; for intermittent shocks, consult our engineering team. Q: What’s the max speed limit? A: Up to 3,200 rpm (51120, grease-lubricated, light load).
