What the designation 22219 E means
| Code | Meaning |
|---|---|
| 222 | Spherical roller bearing, double row self-aligning, light series |
| 19 | bore code "19" = 19 × 5 = 95 mm |
| E | Optimized internal design |
Basic rating life of the 22219 E
Basic rating life is L10 = (C / P)p million revolutions, where P is the equivalent dynamic load and p = 10/3 (roller bearing). For a 22219 E with C = 393 kN, the table shows what that gives at different load levels. It is the ISO 281 basic life only: it does not include lubrication, contamination, misalignment or reliability modifiers.
| C / P | P as share of C | L10 (million rev) | L10 at 1,500 rpm | L10 at 3,000 rpm |
|---|---|---|---|---|
| 3 | 33.3% | 39 | 430 | 220 |
| 5 | 20.0% | 214 | 2,400 | 1,200 |
| 8 | 12.5% | 1,024 | 11,400 | 5,700 |
| 12 | 8.3% | 3,956 | 44,000 | 22,000 |
For example, a C / P of 5 means the equivalent load is 78.6 kN on this bearing. Use the Load Calculator to work out P for your actual radial and axial loads.
Equivalents of the 22219 E from other brands
These parts share the main boundary dimensions of the 22219 E and are commonly used as its equivalent. Published load ratings differ a little between makers because internal designs differ.
| Brand | Part | C (kN) | C0 (kN) | Dynamic rating vs SKF |
|---|---|---|---|---|
| SKF | 22219 E | 393 | 450 | Reference |
| FAG | 22219-E1 | 380 | 415 | 97% of SKF |
Check clearance class, cage, seals and any special suffix before ordering. A matching main size does not guarantee the parts are interchangeable in every detail.
Where the 22219 E is used
Spherical roller bearings are chosen for: Very high radial load with misalignment capability. Typical equipment: Crushers, mills, conveyors, wind main shafts, paper machines. Robust for shock/dust; lubrication and sealing are crucial.
Other sizes in the same series

Common problems on bearings like the 22219 E
Most field failures trace back to lubrication, contamination, fits and alignment rather than the bearing itself. These guides explain how to recognise and prevent them:
