High Quality Self-Aligning Ball Bearings (2209, 2210, 2212, 2213, 2214, 2216) are designed to accommodate misalignment and axial loads in heavy-duty applications. Key parameters include:
| Model | Bore Diameter (mm) | Outer Diameter (mm) | Dynamic Load (kN) | Speed Limit (rpm) |
|---|---|---|---|---|
| 2209 | 45 | 85 | 32.5 | 6,000 |
| 2210 | 50 | 90 | 35.1 | 5,600 |
| 2212 | 60 | 110 | 48.5 | 4,800 |
| 2216 | 80 | 140 | 61.2 | 3,800 |
Note: All models feature double-row radial design for enhanced stability [4].
These bearings are critical in.
The self-aligning capability (±3° angular compensation) makes them ideal for applications with mounting errors or shaft deflection [4][10].
Model 2213 bearings reduced downtime by 40% in high-temperature kiln operations through improved heat resistance (up to 200°C continuous operation).
2210 series enabled 15% longer maintenance intervals in offshore wind farms by withstanding saltwater corrosion [6].
Challenge: Vibration issues in robotic assembly lines.
Solution: 2209 bearings with advanced damping reduced noise levels by 12dB.
Result: 18-month warranty period achieved with zero failures.
Challenge: Frequent bearing replacements in rolling mills.
Solution: Customized 2216 bearings with reinforced cages.
Result: 300% increase in service life compared to standard models [6][10].
