Table 4 PFs and FPs under inner race fault

From: Generalized Demodulation Transform for Bearing Fault Diagnosis Under Nonstationary Conditions and Gear Noise Interferences

Fault type	PF	FP
Outer race	S_o(t) = F_o × C_s	f_po(t) = F_o × C_f = 94.13 Hz
Inner race	S_i(t) = F_i × C_s	f_pi(t) = F_i × C_f = 152.77 Hz
Ball	S_b(t) = F_b × C_s	f_pb(t) = F_b × C_f = 61.41 Hz
