What the designation 6222 means
| Code | Meaning |
|---|---|
| 62 | Deep groove ball bearing, light dimension series |
| 22 | bore code "22" = 22 × 5 = 110 mm |
Basic rating life of the 6222
Basic rating life is L10 = (C / P)p million revolutions, where P is the equivalent dynamic load and p = 3 (ball bearing). For a 6222 with C = 151 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% | 27 | 300 | 150 |
| 5 | 20.0% | 125 | 1,400 | 690 |
| 8 | 12.5% | 512 | 5,700 | 2,800 |
| 12 | 8.3% | 1,728 | 19,200 | 9,600 |
For example, a C / P of 5 means the equivalent load is 30.2 kN on this bearing. Use the Load Calculator to work out P for your actual radial and axial loads.
Equivalents of the 6222 from other brands
These parts share the main boundary dimensions of the 6222 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 | 6222 | 151 | 118 | Reference |
| Timken | 6222 | 144 | 117 | 95% 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 6222 is used
Deep-groove ball bearings are chosen for: Radial load with moderate axial load; high-speed compact equipment. Typical equipment: Motors, fans, pumps, gearboxes, auxiliaries. Single/multi-row; insulated or stainless variants available.
Other sizes in the same series
The 6222 belongs to the “62 light” series. The next size down, the 6220, has a bore of 100 mm and a dynamic rating of 127 kN. The next size up, the 6224, has a bore of 120 mm and a rating of 146 kN (-3%).
Common problems on bearings like the 6222
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:
