Vibration Analysis

Vibration Analysis

Vibration is slowly tearing your equipment apart… Stopping it is a balancing act for experts.

Sooner or later, every piece of rotating equipment is going to show the very real damage that vibration does. You are going to pay the price for not seeing it sooner; in repair costs, production downtime, and in damage to materials and related components. Raynesford Balancing has remained a trusted leader in Southern and Central California vibration analysis since our inception in 1931.

Mechanical vibration provides invaluable information on the health of your rotating equipment, similarly to how an EKG helps to evaluate our health. Raynesford’s state-of-the-art equipment and diagnostic techniques predict problems well in advance of breakdown, reducing unexpected downtime and repair costs.

If you have a service requirement for machinery vibration analysis and special testing, contact us so we can quickly resolve your machinery problems and put you back on the path of profitability.



  • Save on Repair and Production Costs
  • Conveniently Schedule Maintenance Repairs
  • Create Reliable Equipment that Lasts for Years
  • Drastically Reduce Production Downtime/Cost
  • Diminish Large Scale Repairs and Failures
  • Reduce Maintenance Costs


Periodic Vibration Survey

Even with the best maintenance practices, machinery is never reliable enough. Gain confidence in your machinery’s reliability through our predictive maintenance program. Raynesford personnel can periodically conduct vibration surveys on your equipment to identify maintenance problems well in advance of failure. We can analyze the data on the spot, providing your maintenance team with immediate feedback on recent repairs.



Startup / Acceptance Testing

Raynesford Balancing Service protects your investment by evaluating new or reconditioned equipment before you accept it from the manufacturer or contractor. Our analysis compares your equipment’s health to the accepted industrial standards to ensure you receive a quality product. In addition, we create a baseline to evaluate the machine’s future health. This allows the realization of improved productivity and cost savings. 

Today’s emphasis on energy efficient motors with variable frequency drives has opened a Pandora’s Box of vibration issues. In the past, machinery was manufactured for specific operating speeds so it was simple to determine resonant vibration problems associated with the expected operating speed. Now the operating speed varies greatly and for these type of machines, you cannot afford to skip the startup and acceptance tests, or you may risk the future condition of your business.



  • Diagnose equipment problems prior to purchases/warranty expiration/shutdowns
  • Ensure reliable equipment during production
  • Reduce operational costs
  • Establish predictive maintenance baseline
  • Preclude acceptance of deficient equipment

We have helped customers from diverse industries:

  • HVAC Contractors
  • Property Management
  • Building Engineers
  • Manufacturers (large & small)
  • HVAC Manufacturers
  • Government
  • Television/Film Studios
  • Hospitals
  • Hotels
  • Restaurants/Food Production

We can identify:

  • Unbalance
  • Misalignment
  • Looseness (in bearings, parts or structures)
  • Resonance
  • Critical Speeds
  • Deteriorating Bearing Elements
  • Vibration from adjacent equipment

Typical Trouble Areas:

  • Fans
  • Motors
  • Pumps
  • Compressors
  • Gearboxes
  • Cooling Towers
  • Bearings
  • Shafts
  • Impellers
  • Mills
  • Couplings
  • Structures

On-Site Balancing

Unbalance is often the source of excess vibration in rotating equipment. Out-of-spec vibration will shorten the life of your bearings and fatigue other components. Dynamic balancing in the field can remove this potential damage.

Vibration Analysis

This is one of the tools used in Root Cause Analysis, using the vibration signaure of your equipment to diagnose problems and recommend solutions.

Periodic Condition Monitoring

Vibration surveys show the current and future condition of your equipment to provide a heads-up for preventative maintenenace planning.
