Lubrication condition
| Lubrication condition | κ | Size selection |
|
Boundary lubrication Full asperity contact, wear without EP/AW additives, high friction |
κ ≤ 0,1 |
static safety factor |
|
Mixed lubrication Reducing asperity contact, wear and surface fatigue without EP/AW additives, friction reduced |
0.1 < κ ≤ 4 |
SKF rating life and static safety factor1) |
|
Full film lubrication No asperity contact, increasing viscous frictional moment |
κ > 4 |
SKF rating life (no life gain, possible higher temperatures) and static safety factor1) |
- 1) This applies to peak load.
