Table 2 Characteristics of bearings for different conditions.
From: An efficient bearing fault detection strategy based on a hybrid machine learning technique
Condition | Fault type | Fault location | Fault diameter (mils) | Operating load (Hp) | Motor speed (rpm) | Sampling rate (Hz) | Power (Hp) |
