JPI understands the importance of precision survey and layout. We work with you to establish perfect center lines and elevations for all of your operating systems, equipment and building specifications. Our abilities include complete plant layout or evaluation of existing center lines and movement. Stability and proper alignment are critical factors that ensure the production of superior products and boost overall performance.

Precision Measuring

At JPI, we understand the importance of precision. The precision of a measurement system, also called reproducibility, is the degree to which repeated measurements under unchanged conditions show the same results. A measurement system is called valid if it is both accurate and precise. Our state-of-the-art measuring equipment and highly skilled technicians provide the tools that help you measure success.

Coupling Alignment

The primary purpose of couplings is to join two pieces of rotating equipment while permitting some degree of misalignment or end movement or both. JPI will assist by carefully selecting, installing and maintaining of couplings to keep you running smooth. Our partners experience substantial savings by reduced maintenance costs and limited downtime.

Laser Alignment

By allowing JPI’s highly skilled technicians and engineers to align your equipment with Fixturlaser, you will be investing in your company’s future. Proper alignment increases the lifespan of your capital investments, reduces vibration, and decreases critical downtime.
JPI proudly offers Laser and Optical Alignment to a broad range of industries including:

Rolling Mills

Precision Leveling

JPI uses Karl Zeissâ„ AVS JCAM MIC head level and a Nikon electronic digital the-odolite to perform:

Fixed point leveling

Extension of first order leveling nets

Observation of subsidence in mining regions

Above/below ground leveling in heavy machinery and industrial construction

Tachometric leveling/Turning any angles


“We keep you focused and your equipment straight.”

Bore Alignment

J. Poli, Inc. has a multitude of lasers for any precision measurement applications. Using a 2-axis detector and laser transmitter, JPI can measure turbine diaphragms, bearing journals, seals and oil bores for new installations and turbine rebuilds. Our proven alignments processes are done inexpensively, accurately and time matters.

JPI can perform bore alignments by referencing the bore to a center of axis rotation, or a center of bore as reference. These alignments are ideal for extruder tube applications which allows for increased screw lifetime and production time, decreases in scrap and improved product quality.

Geometric Measurement

J. Poli, Inc. uses advanced laser technology that allows measurement of flatness, straightness, parallel, perpendicularity, and relative position of any machined surface.

Reliability Maintenance

JPI uses numerous tools to offer improvements for multiple industries to establish safe and productive levels of maintenance. Reliability centered maintenance is an engineering framework that enables the definition of a complete maintenance regime. It regards maintenance as the means to maintain the functions a user may require of machinery in a defined operating context. As a discipline it enables machinery stakeholders to monitor, assess, predict and generally understand the working of their physical assets.
