Example #2: A Bearing Vibrates 10 Mils Pk-Pk At 1000 cpm

Displacement @ 1x rpm = 10 mils	Displacement @ 1x rpm = 250 um
English Units: Velocity = 0.000052 x D x F V = 0.000052 x 10 mils x 1000 cpm	Metric Units: Velocity = 0.000052 x D x F V = 0.000052 x 250 um x 1000 cpm
V = 0.52 ips	V = 13 mm/sec
Acceleration = 0.00027 x V x F A = 0.00027 x 0.52 x 1000	Acceleration = 0.0000107 x V x F A = 0.0000107 x 13 x 1000
A = 0.14 g's	A = 0.14 g's

Failure Likelihood: Stress = MODERATE Fatigue = MODERATE Force = None

What unit is best to monitor with at this frequency ? Velocity Why not displacement ? Because it can also be used to monitor higher frequencies on this machine.
