What the designation 6020 means
| Code | Meaning |
|---|---|
| 60 | Deep groove ball bearing, extra-light dimension series |
| 20 | bore code "20" = 20 × 5 = 100 mm |
Basic rating life of the 6020
Basic rating life is L10 = (C / P)p million revolutions, where P is the equivalent dynamic load and p = 3 (ball bearing). For a 6020 with C = 63.7 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 12.74 kN on this bearing. Use the Load Calculator to work out P for your actual radial and axial loads.
Equivalents of the 6020 from other brands
Deep groove ball bearings follow the ISO basic designation system, so the base number 6020 means the same bore (100 mm) and outside diameter (150 mm) at the major makers. Only the suffixes differ. For sealed versions, common suffixes are -2RS1 or -2Z at SKF, -2RSR or -2ZR at FAG, DDU or ZZ at NSK, and LLU or ZZ at NTN. Check clearance class, grease and seal type before substituting. Rotec AI has no brand-specific part numbers catalogued for the 6020 yet; the Cross-Reference tool shows what is catalogued for other sizes.
Where the 6020 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 6020 is size 21 of 21 in the Rotec AI catalogue for the “60 extra-light” series. The next size down, the 6019, has a bore of 95 mm and a dynamic rating of 63.7 kN.
Common problems on bearings like the 6020
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:
