What the designation 6000 means
| Code | Meaning |
|---|---|
| 60 | Deep groove ball bearing, extra-light dimension series |
| 00 | bore code "00" = 10 mm (one of the four fixed small-bore codes, not the ×5 rule) |
Basic rating life of the 6000
Basic rating life is L10 = (C / P)p million revolutions, where P is the equivalent dynamic load and p = 3 (ball bearing). For a 6000 with C = 4.75 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 0.95 kN on this bearing. Use the Load Calculator to work out P for your actual radial and axial loads.
Equivalents of the 6000 from other brands
Deep groove ball bearings follow the ISO basic designation system, so the base number 6000 means the same bore (10 mm) and outside diameter (26 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 6000 yet; the Cross-Reference tool shows what is catalogued for other sizes.
Where the 6000 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 6000 is size 1 of 21 in the Rotec AI catalogue for the “60 extra-light” series. The next size up, the 6001, has a bore of 12 mm and a rating of 5.4 kN (+14%).
Common problems on bearings like the 6000
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:
