Mechanical Contractor


Onsite Field Service

  • When is your next scheduled maintenance due?

  • Are you ready for the upcoming plant shutdown?

  • Are you shorthanded?

If you’re lucky, you have all the right equipment, skills, technicians, and time to handle every precision mechanical service necessary, across the full spectrum of routine electric motor installation, maintenance, repair, and replacement.


Maybe you even have a preventative maintenance (PM) schedule and enough time and manpower to follow it. Unfortunately, that’s seldom the case.

If you’re too short-staffed or under-equipped to sustain a regular preventative maintenance, Square One Electric Motor’s Industrial Response Team is ready to provide the service you need right now.

For decades, Square One has provided on-site rotating equipment repair services to manufacturers, municipalities, and countless other businesses in Delaware, Maryland, New Jersey, and Pennsylvania.

Vibration Analysis and Monitoring


Sure, the scream of howling bearings will tell you something’s wrong. So will sparks, plumes of white smoke, and the sound of a maintenance technician cancelling plans for that evening (these things happen exclusively on Friday afternoons).

A catastrophic failure makes itself a priority over everything in the company until it’s resolved. Amid the downtime loss, overtime wages, and expedited service bills, it’s going to be expensive, too.


Wouldn’t it be great to avoid this kind of mess?

Vibration analysis is the front-line defense against unforeseen equipment failure. It is used for the early detection of potential failures in virtually all rotating equipment, from electric motors and pumps to fans, blowers, conveyors, crushers, gearboxes, extruders, and compressors.

Square One Electric Motor field technicians will come to your facility with a spectrum analyzer and dynamic balancer.

  • Using sensors, we will take vertical, horizontal, and axial readings on your critical rotating equipment while it’s operating under a load in its native environment and application.

  • Using the analyzer, we will measure the prominent sources of vibration within your equipment, and then identify and isolate the frequencies of specific parts and mating surfaces, such as motor shafts or bearings.

During analysis, our technicians look for vibrations that either exceed manufacturer specs or simply do not belong in the apparatus.


Through spectrum analysis, they isolate normal noise from irregularities caused by looseness, resonance, or worn or defective components; and observe the equipment’s environment and rigging to identify any external forces contributing to the vibrating condition, such as softfoot.

Though a one-time analysis can be helpful in diagnosing a specific problem, effective PM requires a way to measure changes in your equipment over time.


At the start of a PM program, we will monitor your equipment a few times to establish a baseline against which all future readings can be compared. As the PM cycle continues, we compare successive readings against the baseline data, noting any sudden or gradual changes.

Our electromechanical experts will provide a report for each unit that includes an analysis and recommendations—if any—for corrective action.


Because Square One Electric Motors is, at heart, an electromechanical repair company, the experts who interpret your equipment’s vibration data will be the same mechanics who service and repair your equipment.


This allows Square One to offer the continuity and convenience that most maintenance contractors do not provide.


Dynamic Balancing


Blown bearings or other mechanical faults are frequent culprits for vibration, but not always.


Normal wear and tear can cause an imbalance condition, and it, too, will destroy rotating equipment.

Imbalance occurs naturally when parts break down and gaps extend beyond factory tolerances in gears, couplings, and other components. Sometimes, it is the result of damage to shafts or rotating blades, or even defects in the metal itself.

The cumulative hammering effect of a small imbalance, spinning upwards of 3600 rpm, will eventually lead to failure. Speed amplifies the destructive forces involved in an imbalance condition.


The centrifugal force causing the vibration does not increase proportionally to the rotating speed—when the speed doubles, the force quadruples. As parts wear down, the increased displacement (space between the parts) further increases the destructive force.

Quite often, vibration caused by imbalance can be resolved on-site, as is the case with most fans, blowers, and HVAC units.


Square One’s technicians will:

  • First, evaluate the apparatus to ensure components are properly mounted, coupled, and aligned.

  • They will then perform an on-site vibration analysis to determine the severity and location of imbalances.

  • Through dynamic balancing, the technicians will then correct the mass distribution of the imbalanced component by adding or reducing weight in the correct locations.

Regular dynamic balancing is a small investment for the generous returns, such as:

  • extended machine life.

  • reduced operating costs.

  • increased workplace safety.

  • less noise.

  • reduced structural stress.

  • fewer parts and unscheduled repairs.

  • improved product quality.


Periodic vibration analysis and dynamic balancing spots problems while they’re small, allowing you to schedule maintenance or repairs on your time instead of waiting until a failure brings the whole operation to a halt.

Laser Alignment


Vibration is not always a direct result of worn or damaged parts, but instead a symptom of misaligned components.


Perfect alignment is critical during assembly or installation of coupled equipment, and it must be monitored for change as the equipment wears.


Couplings, pulleys, gears, and sheaves wear out, changing belt, shaft, and drive chain angles. Mounting bolts work loose. Bases crack and materials flex.


Periodic alignment checks are critical.

Square One regularly performs laser shaft alignment for the following applications:

  • Gearbox couplings and bearings

  • Compressor shafts

  • Pump couplings, bearings, and seals

  • Drive shafts

  • Diesel and gas engine generating sets

  • Gas and steam turbines

  • Rollers and chocks

  • Printing machines


Square One Electric Motors will perform on-site laser alignment and provide a report of our analysis and any necessary adjustments or recommendations.


A misalignment condition hinders everything in a system. Excess friction increases the load on a motor and reduces efficiency. Bearings and seals fail prematurely.

You don’t think twice about getting your new car tires balanced or aligned - it’s common sense. And unlike electric motors, car tires usually aren’t expected to run at high rpms 24 hours a day, keeping your organization in business.

Reap the benefits and save your company the pain and expense of failure by setting up a preventative maintenance program with Square One Electric Motors.
