At Precision Balancing we offer a range of services including Dynamic and Static Industrial Balancing, Vibration Diagnostics, and Fault Investigation. We can perform static and dynamic industrial balancing, to the ISO1940-1-2003 standard, at the required quality grade (G1, G2.5, G6.3, etc)

We utilise a large variety of specialised equipment including a range of Schenck hard bearing balancing machines. We use digital technology and provide detailed printed reports for every project; we keep these reports on record for 5 years. The full report is given to the client including the values of the residual unbalance.

The workshop consists of three Schenk Hard-Bearing Balancing Machines namely a H20, H30 and a H40. Precision Balancing also have a fourth balancing machine for tailshaft balancing.

The H20 Schenck
The smallest machine, the H20, has the ability of Dynamically Balancing components as low as 300 gram sin weight and up to 50 kilograms in both direct drive and belt drive arrangements.

The H30 Schenck
The H30 above is shown with a successfully balanced 36" diameter impeller. The computer screen, showing 2 green flags side by side, indicates that the work piece is within its balancing tolerance. This machine has a capacity of 15kg up to 500 kg and can be arranged as a direct drive unit, as shown, or as a belt drive unit to take a work piece that may be up to 3000mm long between centres.

The H40 Schenck
With a 5000kg capacity, the H40 is able to accept rotors that have a maximum diameter of 2650mm at a total length of 6 metres. The five tonne overhead crane situated above the H40 ensures the work piece is positioned on the machine safely. This machine has been deliberately designed to take this scale of work and still has the sensitivity to balance to a grade of up to G0.4 to the ISO Standard. It also is backed up with a CAB 690.
The periodical servicing and calibration of our balancing machines is very important so we can continue providing optimal productivity, accuracy and reliability. Schenck Australia regularly calibrates all the Precision Balancing machines and ensures all mechanical and electrical components operate and function to their optimum level.

To ensure our clients quality we follow a regulated procedure, to ensure your project is correctly handled:

  • Every item that comes into the workshop is given a job number and job sheet, as a rule every purchase order must have a unique job number.
  • Every Job sheet must show any balance speed and balancing grade required and any special requirements for the customer.
  • Job is weighed and detailed on the job card
  • Job is allocated to the balancing machine appropriate to its size (i.e. H20, H30, H40)
  • We calculate the balancing tolerance (based on weight and balancing grade required.)
  • We select an appropriately sized Mandrel (if the item does not have its own shaft.) and apply lubricant to the bearing surfaces.
  • Input the item dimensions into the balancing machine and run the job. We add or remove weight to achieve dynamic balance within client’s specifications. Note that some jobs have specific requirements. E.g. Pump impellers are remove weight only. Special coatings may require bolt on Stainless Steel weights. Care must be taken to ensure added weights are of the same material and are welded using correct wire and gas.
  • Print out Balance Certificate which has the job number and customers order noted on it. If the customer has requested supply a copy of the certificate with the job. (Print / Email)
