Product Details
SKF High-Quality Thrust Ball Bearing 51124 / 51126 / 51128 – Precision Engineered for Axial Load Excellence
| Description | Key Value |
|---|---|
| Precision & Tolerance | P0–P2 grades (highest accuracy per ISO) |
| Load Capacity | Optimized for pure axial thrust loads (0° contact angle) |
| Dimensions (mm) | 70 × 125 × 40 – compact yet robust design |
| Material | High-purity bearing steel (GCr15 equivalent), hardened & ground |
| Lubrication Flexibility | Compatible with grease or oil – ideal for diverse OEM environments |
| Vibration Control | Z1V1 to Z3V3 grading – ultra-low noise for precision machinery |
| Quality Assurance | ISO 9001:2008 certified; manufactured in Japan |
| Design Type | Non-aligning, separable single-row thrust bearing |
| Application Scope | CNC spindles, hydraulic pumps, automotive transmissions, industrial gearboxes |
| Competitive Edge | Superior surface finish & raceway geometry vs. standard Grade P0 – extends service life by ≥30% |
Engineered for reliability under high-speed axial loads, SKF’s 51124/26/28 series delivers unmatched rotational stability and minimal heat generation. Its Japanese-origin manufacturing, strict vibration control (Z2V2+), and separable design simplify maintenance and replacement — reducing downtime across heavy-duty applications.
Frequently Asked Questions:
Q: Can this bearing handle radial loads?
A: No — designed exclusively for axial (thrust) loads. Use paired with radial bearings for combined loading.
Q: Is pre-lubrication included?
A: Yes — factory-greased with high-temperature lithium complex grease (NLGI #2).
Q: What’s the max recommended speed (rpm)?
A: Up to 3,200 rpm (with proper lubrication and cooling).
