3.5. Shaft Loads
3.5.1. Vibration resistance toshaft end
Frequency domain :10 to 55 Hz according to EN 60068 -2-6
Vibration resistance to the shaft end :
- radial 3 g
- axial 1 g
3.5.2. Maximum load acceptable on the shaft
Notice: Curves below are valid only for horizontal mounting and a life
time L10 of 20 000h at constant speed in accordance with ISO281.
Notice: Radial and Axial Loads are not additive.
3.5.2.1. EY310
The bearing arrangement is made with 2 ball bearings (one on the
shaft end + another on the rear). The rear bearing is blocked in axial
translation and the front one is free in translation to avoid any stress
from the shaft thermal expansion during the running.
So, it is important not to block in translation the shaft expansion by any
extra bearing or similar device.
