Improve quality, production and safety with Precision Balancing Imbalance is the most common cause of vibration in rotating equipment. Did you know that vibration can lead to machine problems through mechanical stress, increase energy consumption and reduced production time?

QUALTEX alignment, balancing mechanical services offer highly effective methods to help organisations reduce total machine related costs, enhance productivity and strengthen profitability. Not only do we service and balance machines, but we understand the bigger picture of the effects it has on your business.  

Unbalanced machines cause an increased load on bearings and is a common cause of vibration that can lead to: structural fracture bearing failure damage to equipment reduced reliability     What causes a component to become unbalanced? Unbalance is caused by the displacement of the mass centerline from the rotor’s axis by an eccentricity in the distribution of the rotor mass.  

What is balancing? Balancing is the correction of this, by the removal or addition of mass to the component, compensating for centerline error.   Static balancing involves installing the component in a balancing machine and measuring the ‘heavy’ point in relation to the centerline, while the part is rotating. If the required balance correction is at a single axial point on the rotor the balance is said to be ‘Single-Plane’.

Single plane balancing is adequate for rotors which are short in length, such as narrow section pulleys and fans.  Dynamic balancing is required for the majority of components or assemblies of significant length, particularly rotors. Rotors can have two ‘heavy’ points at opposing ends of the component, acting independently on the mass centerline. In order to balance the component, both planes must be corrected for centerline error. Dynamic balancing is required for components such as shafts and multi-rotor assemblies.

Our QUALTEX workshop has a balancing machine capable of taking loads of 4kg up to 4000kg for conducting precision balancing of rotating components.  A comprehensive onsite balancing service can also be performed to avoid the need for machinery removal. Whether you’re dealing with precision spindles, rotors for the aeronautical industries, high-speed tools or drive components, our balancing service will assure the highest level of quality for your high-performance machinery, including the issue of detailed reports.  

Typical applications include: • High speed machine tools components • Impellers • Centrifuge rotors • Electric motor rotors/armatures • Fan and blowers • Compressor rotors  Turbochargers • Turbine rotorsIn recent years, it has been a clear trend in many industries to outsource non-core maintenance to specialist engineering product and service providers to reduce total maintenance costs.
