Product Details
High-Quality 51216–51220 Thrust Ball Bearings – Precision, Durability & OEM-Ready
| Description | Key Selling Points |
|---|---|
| Model Range | 51216 / 51217 / 51218 / 51220 — standardized ISO thrust bearing series for global interchangeability |
| Dimensions (mm) | 80×115×28 — optimized axial load capacity with compact footprint |
| Precision Grades | P0 to P2 — ultra-tight tolerances for high-speed, low-vibration applications |
| Vibration Levels | Z1V1 to Z3V3 certified — ideal for noise-sensitive machinery (e.g., medical devices, precision spindles) |
| Lubrication Flexibility | Grease or oil compatible — extended service life under variable operating conditions |
| Material & Hardness | GCr15 bearing steel, heat-treated — superior wear resistance and fatigue strength |
| Single-direction thrust only — engineered for pure axial loads with minimal radial deviation | |
| Quality Assurance | ISO 9001:2008 certified + 100% in-house testing — zero defect tolerance before shipment |
| OEM/ODM Support | Custom branding (BDL), packaging, and specs — seamless integration into your supply chain |
| Stock & Lead Time | Immediately available — no MOQ, fast dispatch from China warehouse |
Applications: Hydraulic pumps, crane turntables, machine tool rotary tables, automotive steering columns, and industrial gearboxes.
Why Choose These Over Generic Brands? Higher precision grades (P2/P4), stricter vibration control (Z3V3), and full traceability vs. uncertified imports — proven reliability in demanding duty cycles.
FAQ: Q: Are these interchangeable with SKF 512xx series? A: Yes — identical dimensions and load ratings; ideal drop-in replacement where SKF cost or lead time is prohibitive. Q: Can they handle shock loads? A: Designed for steady axial thrust; for intermittent shock, consult our engineering team for reinforced variants. Q: What’s the max speed limit? A: Up to 3,200 rpm (with proper lubrication and cooling).
