Home / Services / Onsite Dynamic Balancing
In-place single-plane and two-plane dynamic balancing for industrial fans, blowers, rotors and other rotating equipment—performed at your facility under actual operating conditions.
Request a balancing assessment when a fan, blower or rotor develops excessive vibration, recurring bearing problems, increased noise or an operating condition that suggests uneven rotating mass.
Before applying correction weights, VibeLube evaluates the vibration and operating condition to determine whether imbalance is the primary problem or whether looseness, misalignment, resonance, structural issues or other faults may be contributing.
Fans and rotors may lose their original balance condition because of transportation and installation, blade repairs, process-material buildup, cleaning, bearing replacement, erosion, corrosion, wear or previous unsuccessful balancing attempts.
VibeLube performs field balancing with the rotor installed in its own bearings. The procedure is adapted to the machine, operating conditions, available access and whether single-plane or two-plane correction is appropriate.
Review the reported problem, operating history and recent maintenance. Initial vibration measurements help determine whether imbalance is likely to be the primary fault and whether other conditions may be contributing.
Collect vibration amplitude and phase-reference data under suitable operating conditions. When appropriate, a controlled trial-weight run is used to measure the rotor’s response.
Use the measured response to calculate the required correction-weight amount and angular position for the selected balance plane or planes. Correction weights are applied using an appropriate secure method.
Complete a verification run to compare the as-found and as-left condition. Document the resulting vibration levels, work performed and any additional observations or recommendations.
Important: Onsite balancing requires safe access to measurement locations and suitable correction-weight positions. The equipment must be capable of operating through the required measurement and verification runs. Any cleaning, repairs or mechanical defects that could change the balance condition should be addressed before final correction.
VibeLube specializes in onsite balancing of industrial and commercial fans, blowers and other rotating assemblies. Suitability is confirmed according to the machine, rotor construction, operating condition, access and available correction locations.
Field balancing allows the installed rotating assembly to be evaluated and corrected in its own bearings and under actual operating conditions, when the machine and site are suitable for the procedure.
Manufacturing, processing and production plants; hospitals; government and office buildings; colleges and universities; malls; warehouses; logistics facilities; and other sites operating critical fans and rotating equipment.
There is no single balance target appropriate for every installed machine. The acceptance criteria must reflect the rotor, operating speed, machine application, manufacturer guidance, operating history and purpose of the balancing work.
Where applicable, VibeLube considers recognized balancing guidance such as ISO 21940-11, together with relevant machinery-vibration criteria and the agreed service objective.
After the correction weights are applied, VibeLube performs a verification run under suitable operating conditions. The resulting vibration is compared with the initial condition and the selected balancing objective.
Final documentation is adapted to the equipment, project scope and measurements collected. Correction is only performed when the machine condition, access and operating environment support a safe and technically appropriate balancing procedure.
Roy is a mechanical engineer and predictive-maintenance professional with more than 35 years of industrial experience and more than 20 years dedicated to condition monitoring and machinery diagnostics.
His field-service background includes single-plane and two-plane dynamic balancing, advanced vibration analysis, shaft alignment, bearing diagnostics and the investigation of mechanical conditions affecting industrial fans and rotating equipment.
Roy approaches every balancing job as a diagnostic problem first. The objective is to confirm whether imbalance is responsible, identify contributing conditions, calculate an appropriate correction and verify the machine’s response after the work is completed.
Onsite dynamic balancing—also called field or in-situ balancing—is performed with the rotating assembly installed in its own bearings. Vibration and phase measurements are used to calculate an appropriate correction-weight amount and location under suitable operating conditions.
Common indications include excessive running-speed vibration, increased noise, recurring bearing problems, visible movement, unstable operation or vibration following installation, cleaning, repair or blade replacement. Vibration measurements are required to determine whether imbalance is actually the primary cause.
No. Misalignment, mechanical looseness, resonance, bearing defects, structural flexibility, aerodynamic forces and other conditions can produce similar symptoms. VibeLube evaluates the vibration and operating condition before applying correction weights.
Single-plane balancing corrects an imbalance condition using one correction plane. Two-plane balancing uses two correction planes and may be required when a rotor’s width, speed and dynamic behaviour create a couple or combined imbalance condition. The appropriate method depends on the rotor and measured response.
In many suitable applications, the rotating assembly remains installed and is balanced in its own bearings. The equipment must be capable of operating through the required measurement runs, and there must be safe access to measurement points and secure correction-weight locations.
The machine should be safely accessible and mechanically ready to operate. Heavy buildup, loose components, damaged blades and known mechanical defects should be addressed where practical because they can affect the final balance condition. Please provide available speed, equipment, maintenance and operating information in advance.
Tell us about the equipment, vibration concern, operating speed, recent maintenance and facility location. VibeLube can help determine whether an onsite balancing assessment is the appropriate next step.
