Machine Tools

Poor finish, ovality, chatter and reduced tool life can all be consequences of excessive imbalance on the tool, tool holder, spindle or drive motor.

Condition Based Maintenance

An important part of modern maintenance strategy must include, where appropriate, the effective use of condition monitoring. The choice of monitoring equipment and its operating costs can be staggering.

High Speed Electric Motors

Balancing electric motors is essential, balancing high speed electric motors needs further focus on assembly tolerances and often proof balancing of the built up housing assembly. Vibration Free proof balance to 18,000 RPM

Vibration Free is based in Oxfordshire and is easily accessible to the M40 (near junction 10) and the M1. Our workshop facility has various balancing machines that handle rotors up to 3000kg, a small machine shop and training room. Two car ramps are available for in-situ vehicle analysis.

Dynamic Table Engine Balancing

Vibration in an engine regardless of its source, is detrimental to power, performance and longevity. Vibration is wasted energy and it can be greatly reduced by balancing all the rotating and reciprocating parts to finer tolerances than traditionally found in common practice.

Large FD Fan Balancing

Vibration Free support many aspects through the design and build process. Assisting companies to reduce build costs and maximise product quality and performance.

Marine Engine and Gearbox Vibration Analysis

Vibration Free often work on site to resolve vibration issues across all industrial sectors

Shredding Machine

As components wear and cutters, blades, hammers are renewed often trim balancing is required. As with hedge cutters, toppers, shredder rotors and decanters.



iRotorBalancer is a technical tool for balancing of rotating machinery in single-plane and two-planes.

The iPad application connects to the hardware to collect the vibration Amplitude and Phase with the accelerometer & the Phase Sensor, and calculates the correction balancing weights and its angular positions.
