The influence-coefficient method achieves residual unbalance well within ISO 21940-11 G6.3 \u2014 and G2.5 or better with care \u2014 which covers fans, pumps, motors, agricultural machinery, and most process equipment. Stationary hard-bearing machines have a slight edge in repeatability for very small, high-speed rotors (toolholders, precision spindles) where the controlled test-stand environment eliminates structural background noise. For in-situ work on any rotor that can be run at operating speed, the portable result is fully adequate and in some respects <em>superior<\/em> \u2014 the correction is valid for the exact conditions the machine actually runs in, including thermal expansion and coupling-induced loads.<\/div>\n<\/details>\n<details>\n<summary>When does a stationary balancing machine make economic sense?<\/summary>\n<div class=\"ans\">When you balance 15&ndash;20 or more identical rotors per day in the same facility. At that throughput, the capital cost of a machine amortises quickly and the fast cycle time (fixed mandrels, known tooling, automated measurement) lowers cost-per-rotor below what a portable setup with manual sensor placement can match. Below that volume \u2014 or if rotor types vary widely \u2014 the tooling and setup cost of a machine erodes the throughput advantage rapidly. Most maintenance departments and field-service contractors never reach the volume threshold where a machine pays back.<\/div>\n<\/details>\n<details>\n<summary>Is it worth repairing an old balancing machine instead of buying a new one?<\/summary>\n<div class=\"ans\">Often yes. The mechanical structure of an old hard-bearing machine \u2014 cradles, bearings, drive \u2014 usually remains serviceable for decades. What fails is the measurement and computing electronics. Replacing just that with a Balanset-1A OEM measuring system costs a fraction of a new machine and delivers modern two-plane digital capability. The same instrument then serves as a portable field balancer when taken off the stand. See the <a href=\"https:\/\/vibromera.eu\/lo\/example\/modernization-of-an-old-balancing-machine-with-hard-bearing-supports\/\">modernization case study<\/a> and the <a href=\"https:\/\/vibromera.eu\/lo\/balancing-catalog\/upgrade-balancing-machine\/\">upgrade guide<\/a>.<\/div>\n<\/details>\n<details>\n<summary>Can the Balanset-1A be integrated into a stationary balancing machine?<\/summary>\n<div class=\"ans\">Yes \u2014 that is one of the explicit design goals of the OEM variant (&euro;1,735). It provides two-channel vibration measurement, RPM reference, and full two-plane software on any hard-bearing or soft-bearing stand. You keep your existing mechanical structure and replace only the instrumentation that has failed or become obsolete.<\/div>\n<\/details>\n<details>\n<summary>What rotor sizes can the portable Balanset-1A handle?<\/summary>\n<div class=\"ans\">There is no upper size limit imposed by the instrument. The sensors clip or magnet-mount on any bearing housing; the laser tachometer works on any shaft where you can place a reflective strip. We have used the Balanset-1A on everything from a 200&nbsp;g micro-fan blade to multi-tonne combine-harvester drums and large centrifuge rotors. The practical lower limit is a few kilograms \u2014 below that, the trial-weight effect can be masked by measurement noise at very low vibration levels, and a dedicated balancing machine spindle with a calibrated arbor gives more control.<\/div>\n<\/details>\n<details>\n<summary>Which method produces a better result for an installed fan or pump that cannot be removed?<\/summary>\n<div class=\"ans\">The portable method is not just better \u2014 it is the only option. A fan or pump impeller installed in its ductwork or casing cannot be placed on a balancing machine without dismounting the entire assembly, which defeats the purpose and adds hours or days of downtime. More importantly, balancing the impeller alone on a machine does not account for the coupling, shaft flex and asymmetric bearing loads that are present at operating speed. Field balancing with the Balanset-1A corrects the entire rotating assembly in the conditions it actually operates in, which is why field-balanced machines often show lower residual vibration than those balanced on a machine and then reinstalled.<\/div>\n<\/details>\n<details>\n<summary>How do I justify the cost of a portable kit to management when we already have a balancing machine?<\/summary>\n<div class=\"ans\">Position it as a complement, not a replacement. Your existing machine handles workshop work on removable rotors. The Balanset-1A handles every rotor that cannot reach the machine \u2014 large fans, installed pumps, driveshafts, field service calls. Calculate the avoided downtime cost on one prevented unplanned shutdown (hourly production loss + emergency parts + labour) and compare to &euro;1,975. Additionally, if a colleague goes on-site for a field-balancing job with the Balanset-1A rather than a contractor, a typical contractor call-out fee covers the instrument cost in one or two jobs.<\/div>\n<\/details>\n<\/div>\n<p><!-- ===== CTA BAND ===== --><\/p>\n<div class=\"vbm-band\">\n<h2>Know which tool fits your job \u2014 then get it working<\/h2>\n<p>If the rotor can run at speed and your team can access the bearing housings, the Balanset-1A delivers two-plane ISO&nbsp;21940-11 balancing in under an hour, at any site, for &euro;1,975 complete. If you are running a high-volume production line on identical small parts, a stationary machine earns its place \u2014 and the Balanset-1A OEM module can still upgrade its measuring system.
