To determine the vibration speed (mm/s), use an electronic vibration
meter and apply it to the following points:
Points P1 and P2 (front bearing): Place the vibration meter close to the
front bearing and log the highest value.
Points P3 and P4 (rear bearing): Place the vibration meter on the frame
of the electric motor, near the bearing housing (not on the fan guard) and

Machine classification:
Class I = SCL with electric motor, power rating
≤15 kW
Class II = SCL with electric motor, power rating >
15 kW
Evaluation zones:
Zone A = vibrations (a) inside this zone are
acceptable for long-term operation.
Zone B = vibrations (a) inside this zone are
acceptable for continuous long-term operation.
The machine may operate in these conditions for
a limited period, till an opportunity for appropriate
corrective maintenance work arises.
Vibration values above zone B may not be considered to be acceptable as they could seriously damage the
machine.
