What the designation 6206 means
| Code | Meaning |
|---|---|
| 62 | Deep groove ball bearing, light dimension series |
| 06 | bore code "06" = 6 × 5 = 30 mm |
Basic rating life of the 6206
Basic rating life is L10 = (C / P)p million revolutions, where P is the equivalent dynamic load and p = 3 (ball bearing). For a 6206 with C = 20.3 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 4.06 kN on this bearing. Use the Load Calculator to work out P for your actual radial and axial loads.
Equivalents of the 6206 from other brands
These parts share the main boundary dimensions of the 6206 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 | 6206 | 20.3 | 11.2 | Reference |
| FAG | 6206-C | 20.8 | 11.2 | 102% of SKF |
| NTN | 6206ZZ | 19.2 | 11.3 | 95% of SKF |
| Timken | 6206 | 19.5 | 11.3 | 96% 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 6206 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.

Common problems on bearings like the 6206
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:
