What the designation 6019 means
| Code | Meaning |
|---|---|
| 60 | Deep groove ball bearing, extra-light dimension series |
| 19 | bore code "19" = 19 × 5 = 95 mm |
Basic rating life of the 6019
Basic rating life is L10 = (C / P)p million revolutions, where P is the equivalent dynamic load and p = 3 (ball bearing). For a 6019 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 6019 from other brands
Deep groove ball bearings follow the ISO basic designation system, so the base number 6019 means the same bore (95 mm) and outside diameter (145 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. For brand-specific part numbers, use the Cross-Reference tool.
Where the 6019 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 6019 belongs to the “60 extra-light” series. The next size down, the 6018, has a bore of 90 mm and a dynamic rating of 60.5 kN. The next size up, the 6020, has a bore of 100 mm and a rating of 63.7 kN (+0%).
Common problems on bearings like the 6019
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:
