The operating temperatures of SKF Energy Efficient bearings and standard SKF bearings were measured at certain speeds and compared (diagram 1). Test conditions were:
- Bearing: 6205-2Z/C3
- Running time: 24 h at each speed interval
- Ambient temperature: room temperature
- Load: 0,5 kN radial
The test showed that when compared to a standard SKF bearing, the E2 bearing ran 5 to 15 °C cooler, depending on speed.
