Balancing in the field, without dismantling. Balancing machines and 24-bit DAQ boards built in our own workshop. Every correction backed by a measurement, every report carrying a QR anyone can verify.
REI Balance is the rotor dynamics unit of Rootcastle Engineering & Innovation.
Place the weight opposite the phase reading (180°), then adjust the mass.
In the field or on the bench the order is the same. No step starts before the previous one has a result.
Horizontal, vertical and axial vibration at every bearing: overall level, spectrum and 1X phase. Simultaneous sampling keeps inter-channel phase error out of the measurement.
Misalignment, looseness, resonance and bearing defects leave different signatures. We read the signature before adding any weight; if the problem lies elsewhere, the report says so.
A trial weight gives the influence coefficient. In two planes the matrix passes a Complex SVD condition check, so a weak trial run is caught before it enters the calculation.

When the field engineer, the machine designer and the signal-processing developer sit at the same table, vibration is solved in every layer, from the sensor to the matrix.
Each work report and certificate we deliver links through its QR code to the verification page on this site. Anyone holding the document, an auditor, an insurer or a new maintenance lead, can enter the number and compare it with the original.

Field balancing corrects a rotor dynamically on its own bearings at running speed, without removing it. A portable vibration analyser and a phase reference sensor measure the amplitude and angle of the unbalance; a correction weight is calculated and added to or removed from the right plane.
Fans and exhausters, pumps, electric motors, crushers, mills, separators, decanters, compressors, turbine and generator rotors, spindles and pulleys: almost any rotating machine with an accessible correction plane.
A typical single-plane fan job usually takes a few hours, depending on access and safe stop-start conditions. For two planes and large rotors the duration is clear after the initial measurement.
For fans, crushers and motor-pump sets that are hard and costly to remove, field balancing is faster and more accurate because it corrects the rotor in its real assembly and speed. Removed rotors in manufacturing, overhaul and series production are balanced on hard-bearing balancing machines. We do both.
On horizontal or vertical machines with a sound frame and bearings we replace the electronics and software: the REI-PRO-04 24-bit simultaneous DAQ board, sensor interface, angle reference and reporting software. The machine brand does not matter; a short inspection decides.
Each document carries a unique number and a QR code. The QR opens the verification page on this site; the number can also be typed in. Validity, revocation and expiry show immediately.
Balance quality is reported against ISO 21940-11 (formerly ISO 1940-1) grades, machine vibration severity against the ISO 20816 / ISO 10816 evaluation zones, and balancing machine acceptance against ISO 21940-21. Customer or manufacturer limits take precedence where they exist.
Yes. We plan international visits for field balancing, machine commissioning and DAQ retrofits; balancing machines and controller boards ship with export documentation. Mention the country and plant in the quote form.
Learn how to set up envelope analysis on site – pick bands, compute BPFO and BPFI, read demodulated spectra, and decide when a bearing needs action.
Learn to find and fix soft foot before aligning a machine, so your laser alignment results hold and bearings last their design life.
Use 1X amplitude, 2X patterns, phase readings across bearings and orbit shapes to separate misalignment from unbalance before you correct a machine.
Tell us the equipment type, speed and the symptom you see. We will agree the measurement plan, the visit date and, if needed, the machine or controller solution.
Hello, I am Sofia. Ask about balancing, vibration, measuring boards or balancing machines; I will point you to the right calculator or the quote form when it helps.
Sofia AI runs on NVIDIA NIM. Answers are preliminary; technical decisions need an on-site measurement.
