Precision Balancing & Vibration Analysis for Critical Rotating Equipment

For more than two decades,A MACO Machinery Company “Shaft Balancing” has provided full-service industrial balancing and vibration analysis for customers across a wide range of industries.

Whether you need a single rotor balanced or a long-term reliability partner, we combine modern instrumentation with practical field experience to solve vibration problems, extend equipment life, and reduce unplanned downtime

Alongside balancing and vibration work, we provide repair and refurbishment services for many types of rotating equipment. Our goal is to return your machinery to service with improved reliability and documented balance condition

Typical repair work

• Air handler and fan repair

Bearing and drive replacements, shaft work, and complete overhauls for air handlers and large fans. We address recurring bearing failures by checking fits, belt tension, and drive sizing

• General equipment repair

Industrial machinery repair across many industries. If it has rotating components, we can inspect, repair, and balance it – from heavy snow-removal equipment to specialized lifting devices and process machinery.

• On-site shaft repair & sleeve solutions

When bearings have worn grooves into a shaft, removal can be costly or impractical. In many cases we can repair the shaft in place using modified bearings and precision sleeves that bridge the worn area, restoring proper fits and reliability without major disassembly

Vibration is rarely caused by a single issue. In many systems, unbalance, misalignment, looseness, bearing wear, and structural problems interact to create complex fault patterns. Our vibration analysis services are designed to separate these effects so you can apply the right correction the first time

What we provide

• Baseline and periodic vibration measurements
• Time waveform and spectrum analysis
• Phase and orbit analysis for rotating machinery
• Identification of unbalance, misalignment, looseness, resonance, and bearing defects
• Recommendations for corrective actions and follow-up verification

Use cases

• Troubleshooting chronic vibration problems
• Verifying new or overhauled equipment before startup
• Building predictive maintenance programs
• Supporting root-cause investigations after failures

Vibration Monitoring & Predictive Maintenance

Rather than waiting for vibration problems to become audible or damaging, we help you implement monitoring programs that track machine condition over time. Trend data makes it possible to plan maintenance windows, avoid unexpected trips, and extend the life of critical assets

Program options

• Periodic route-based vibration checks
• Machine condition baselining and health scoring
• Alarm and alert thresholds tuned to your equipment
• Reporting with actionable recommendations for maintenance and operations

In our balancing facility, we specialize in dynamic balancing and vibration analysis for a wide variety of rotating parts and assemblies. Our in-house capabilities allow us to measure, correct, and document balance quality for components ranging from small precision rotors to long, heavy rolls and shafts

Typical in-shop services

• Dynamic balancing in one or multiple planes
• Whip balancing for long, flexible rotors
• Dimensional inspection and runout checks
• Accurate material removal and correction via in-house machining
• Add-on weight installation, keying, and securement
• Troubleshooting vibration problems that others were unable to resolve

Machining & welding support

• Turning, milling, and other machining operations to support balancing
• Certified welding processes for repairs and build-ups
• Surface restoration, journal repair, and hard-facing for wear surfaces

Typical components we balance

• Process rolls and paper machine rolls
• Fans and blowers
• Impellers, armatures, and rotors
• Turbine and compressor rotors
• Centrifuge and mixer components
• Gears, pulleys, and drive shafts
• Energy storage flywheels
• High-speed machine tooling and spindle components
