Oil Analysis
Vibration Analysis
Our partnership with Reckitt Benckiser
Overview
Vibration data collected from a hydraulic pump motor showed an increase in vibration amplitudes on the motor’s DE bearing, indicating deterioration of a coupling insert.
Site engineers removed the hydraulic pump motor during planned downtime and found the coupling spider badly worn. The coupling was replaced, saving an estimated £3,712 in unplanned downtime cost avoidance.
We provide ongoing vibration testing and oil analysis for a multinational consumer goods company based in the UK. As part of our service, data is collected from multiple moulding machines on a bi-monthly basis.
The challenge
The moulding department of the business is critical to dispense plastic bottles on the production line.
And, as the machines are over 30 years old, obtaining spare parts can be costly and requires long lead times.
The solution
Our reliability engineers provided vibration and Stresswave analysis on the machines to track the health of the assets.
Data was collected from the extruder motor and gearbox, as well as the hydraulic pump motor. Oil samples were taken from the gearboxes and the hydraulic system hammers for signs of wear and free movement.
The result
Vibration data collected in December 2019 on machine 1 (hydraulic pump motor) showed an increase in vibration amplitudes on the motor’s DE bearing. Analysis of the data showed raised levels of synchronous activity with a dominant two times running speed peak – see figure 1.

Due to the motor being mounted upon the tank by means of a spigot, misalignment was ruled out and the most likely cause was identified as deterioration of a coupling insert. Although the vibration amplitudes were not excessive, due to the criticality and time between site visits, it was recommended that further investigation should be carried out on the motor’s coupling insert.
Site engineers removed the hydraulic motor off machine 1 during planned downtime and found the coupling spider badly worn. The coupling was replaced. Data collected off the asset in February 2020 shows vibration levels had returned to historical levels – see figure 2.

Most FMCG production facilities are driven by the requirement for maximum availability and reliability during operation. By identifying this fault, the cost avoidance of planning and execution of maintenance activities to unexpectedly resolve was estimated at £3,713.00.
Key outcomes
Replaced coupling during planned downtime.
Vibration levels returned to historical levels.
Saved an estimated £3,712 in unplanned downtime cost avoidance.
