This being our core activity for more than 14 years as promoters and service providers having the expertise across the segments and equipment specific knowledge, and thereby this rich experience and knowledge, enables our highly experienced engineers and technicians to provide both routine and complex vibration condition monitoring services in an effective and useful manner to the clients.
We are updating our techniques from time to time as per the requirement of our customers as well as upgradation in the technology by procuring latest software and hardware for the instruments/equipment in ensuring customer satisfaction in the field of our expertise.
Most mechanical faults with rotating equipment induce vibration i.e., unbalance, misalignment, looseness caused by poor assembly, deterioration of bearings, wear of gear teeth, etc. Vibration monitoring involves the periodic measurement of machine vibration, usually measured on bearing housings or from the machine supervisor’s panel output/data.
Infrared Thermal Imaging
We deploy handheld thermal imaging systems & trained specialists to identify problems, prevent unscheduled downtime, identify corrective action, and improve plant safety, saving time and money in a wide range of Industrial and commercial applications. Many failure processes generate excess heat, accurately measuring this heat radiation can often provide valuable information to diagnose fault conditions in both mechanical and electrical systems.
Thermography is the remote Condition Monitoring technique that locates these surface temperatures abnormalities and defines their characteristics for use in Preventive Maintenance in your plant.
Using our expertise in Thermography, JN can help you to:
- Locate and eliminate electrical fire hazards.
- Decrease breakdowns due to excessive parts friction (bearings, lubricant or corrosion caused).
- Save costs on shutdowns as measurements can be taken remotely, under operating condition.
Applications – Mechanical systems

The reports:
- Advises on Change of bearings/ spares, at the appropriate time.
- Changing/filling lubricants at appropriate, convenient intervals.
- Recommends your maintenance activities to minimize breakdowns.
- Eliminating unnecessary spares replacement.
- Reduces Maintenance Hours.
- Minimize emergency / unplanned shutdowns.
- Reduces spares cost and extends life of the Equipment and parts.
JN Oil Analysis programs effectively covers the important hydraulic systems, Turbines compressors, gear boxes, pumps, and internal combustion engines.
We offer the following in Oil analysis Program:
- Identify the Critical Equipment &Sample point.
- Installs sampling port.
- Coordinate sample shipments from the lab to your site in time.
- Sampling.
- Work with our lab services division to identify & solve equipment problems.
- Correlate lab results and produce report.
In-situ Dynamic Balancing
Imbalance is the most common machine fault found in rotating assemblies. We perform dynamic balancing by using the latest techniques in the most economical way to correct imbalance in a completely assembled machine, ensuring an increased bearing life and a reduction in the operational noise of the rotating assemblies.
Usually, when an impeller/fan must be dynamically balanced, it is dismantled and sent to the site of a balancing service provider. After the process of balancing has been carried out, it is transported back and reassembled at the original site.
This procedure has the following disadvantages:
- Rotor may get damaged or unbalanced again during transportation or reassembly.
- The procedure is time consuming and involves a costly repair process because of the machine down-time involved.
- In this method, balancing is seldom carried out at true operating speed. Besides, actual operating conditions at the original site such as temperature, relative humidity, etc. cannot be accurately taken into consideration while balancing.
This is where In-situ Dynamic Balancing comes into play.
It is a method which utilizes the existing rotation mechanism of the machine. Vibration is checked at operating speed and analyzed. With the help of a computerized instrument, the required amount and location of the correction mass is determined. After balancing, the rotor is checked again, and it is ensured that the residual unbalance in the rotor is within specified limits under existing site conditions.
Predictive Maintenance team of well qualified and trained staff offers cost effective and reliable balancing services at the client’s site without dismantling the machines. Our specialists can take up the balancing of all the high/medium speed rotating equipment like turbines, compressors, generators, HT/LT motors, I.D/F.D Fans, centrifuges etc.,
“In the site Itself” thereby eliminating the need to dismantle and send the rotor to the repair shop. Many of our customers throughout the globe acknowledge that our services are extremely helpful in running their machinery without any vibration problem, especially in in-situ dynamic balancing.
Laser Alignment
It is proved fact that 50% of machinery failures, including motors failures are due to “Misalignment” of machines. This is the area, which is commonly neglected in many industries; one major reason is that it is difficult and time consuming to perform, often requiring specialist skills to align all machinery accurately. To overcome these problems adaption of Laser alignment technique is most effective solution. All the rotating equipment including high speed turbines, compressors, pumps, fans etc. can be aligned effectively by using our specialized Easy Laser Alignment kits and FAG alignment kit within short duration.
In addition to the above JN is providing the services like leveling, parallelism, flatness, and squareness in all process industries to maintain trouble free operation by using our specialized Easy Laser Alignment kits.
Shaft Alignment can be performed with a lot of different tools. The easiest way is to use a ruler or a straight edge over the two coupling halves and align by eyesight. The result is not very accurate, and it is very operator dependent. A better result can be achieved by the use of mechanical dial indicators. A skilled and experienced operator can obtain good and reliable measurements, but it takes time and patience. A far easier and highly accurate way is to use laser-based alignment systems. They do not require special skills and deliver accurate and reliable results.
Non Destructie Testing
Non-Destructive Testing (NDT) is the process of inspecting, testing, or evaluating materials, components or assemblies for discontinuities, or differences in characteristics without destroying the serviceability of the part or system. In other words, when the inspection or test is completed the part can still be used.
Under NDT we provide the following services:
- Infrared Thermal Imaging (Thermography)
- Dye Penetrant Inspection
- Radiography
- Brinell Hardness Testing
- Boroscopy
- Magnetic Particle Testing
- Ultrasonic Testing
- Leak Detection
- Slow Speed Bearing Monitoring
- Electric Discharge
- Flaw Detection
- Flow Measurement
Infrared Thermal Imaging (Thermography) :
It is the remote Condition Monitoring technique that locates these surface temperatures abnormalities, and defines their characteristics for use in Preventive Maintenance in your plant.
Dye Penetrant Inspection :
It is a method that is used to reveal surface breaking flaws by bleed out of a coloured or fluorescent dye from the flaw. The technique is based on the ability of a liquid to be drawn into a “clean” surface breaking flaw by capillary action. After a period of time called the “dwell,” excess surface penetrant is removed and a developer applied. This acts as a blotter. It draws the penetrant from the flaw to reveal its presence.

Motor Current Signature Analysis
Motor current signature analysis (MCSA) has proven to be a highly valuable predictive maintenance tool. Although it is a relatively young, rarely utilized technology, it is rapidly gaining acceptance in industry today. Mechanical faults related to belts, couplers, alignment, and more are easily found through the use of a demodulated current spectrum.
MCSA is simply the process by which motor current readings are recorded and analyzed in the frequency domain. It has been effective in locating rotor faults and air gap problems in motors.
