NDT & Inspection · Certified · Nationwide

Find the crack before it finds your production line — verify the rebuild before it ships.

Magnetic particle, dye penetrant, ultrasonic, and dimensional inspection under one roof. We inspect incoming cores and validate every rebuild against spec, so nothing leaves the shop until the numbers prove it's right.

Gear Force Machine provides non-destructive testing (NDT) and inspection for industrial gearboxes and machined parts nationwide. We inspect incoming cores and validate every rebuild with magnetic particle, dye penetrant, ultrasonic, and dimensional inspection before the equipment ships — so a hidden crack or an out-of-tolerance wear surface never becomes a field failure.

NDT catches what the eye can't: surface and subsurface cracks, inclusions, fatigue, and wear beyond tolerance. Each inspection produces a written report with the measurements and findings that back the work, documented before and after the rebuild. That verification de-risks the job — you get a rebuild proven to spec, not one you have to take on faith.

Capabilities

Surface, subsurface, and dimension — all verified in-house.

Inspection isn't a box we check at the end. We test the metal, measure the geometry, and document the result, so quality is proven at every stage instead of assumed.

Surface & Subsurface NDT

We locate flaws you can't see. Magnetic particle and dye penetrant reveal surface and near-surface cracks on shafts, gears, and housings, while ultrasonic testing probes for subsurface defects and inclusions deep in the material.

  • Magnetic particle inspection (MPI) for ferrous parts
  • Dye penetrant inspection (DPI) for cracks & porosity
  • Ultrasonic testing (UT) for subsurface flaws

Dimensional & Gear Inspection

Every critical dimension measured against spec. We check gear tooth geometry, backlash, shaft run-out and straightness, and bore and journal fits so the assembly meshes and seats exactly as it should.

  • Shaft run-out, straightness & backlash
  • Gear tooth geometry & contact pattern
  • Bore, journal & bearing-fit measurement

Documented Verification

You get proof, not a promise. Each inspection is captured in a written report with before-and-after findings and a final sign-off, so the condition of the part is documented before it ever leaves the shop.

  • Written inspection report with findings
  • Before-and-after condition documentation
  • Final sign-off & verification before ship
From the Shop
  • Close-up inspection of a machined red gearbox housing interior with the gear stack exposed at Gear Force Machine.
  • An open industrial gearbox with the full gear train exposed during inspection at Gear Force Machine.
  • A rebuilt red gearbox tagged 'GOOD — NO LEAK' after pressure testing and final inspection.
Our Process

Inspect · Test · Measure · Document.

  1. Inspect

    Incoming cores are cleaned and visually inspected. We identify the wear surfaces, load paths, and stress risers that need attention before any rebuild work begins.

  2. Test

    Magnetic particle, dye penetrant, and ultrasonic testing applied to shafts, gears, and housings to reveal surface and subsurface cracks, inclusions, and fatigue.

  3. Measure

    Dimensional inspection of run-out, backlash, tooth geometry, and bore and journal fits, comparing every measurement against OEM tolerance.

  4. Document

    Findings and measurements recorded in a written inspection report, with before-and-after documentation of the part's condition.

  5. Sign Off

    Final verification before shipment. Nothing leaves the shop until the numbers confirm the rebuild meets spec, backed by a documented sign-off.

Frequently Asked

Questions we hear most.

Not sure where to start? Call 832-729-9906 and we'll walk through it with you.

Magnetic particle inspection (MPI) for ferrous parts, dye penetrant inspection (DPI) for surface cracks and porosity, ultrasonic testing (UT) for subsurface flaws and inclusions, and full dimensional and gear inspection. We combine methods to cover both surface and subsurface conditions on shafts, gears, and housings.

Yes. We routinely inspect incoming cores and parts sent in for evaluation, whether or not we're doing the rebuild. Send us the component and we'll run the appropriate NDT and dimensional checks and report exactly what we find. Call 832-729-9906 to arrange an inspection.

Every inspection produces a written report documenting the methods used, the findings, and the measurements against spec, with before-and-after condition records and a final sign-off. That paperwork travels with the part so you have proof of condition for your records and audits.

We verify shaft run-out and straightness, gear tooth geometry and contact pattern, backlash, and bore, journal, and bearing fits against OEM tolerances. Critical surfaces get magnetic particle or dye penetrant testing to catch cracks before assembly, and the finished unit is verified before it ships.

That's the whole point. Fatigue cracks, inclusions, and wear beyond tolerance often hide below the surface long before a part lets go. NDT finds them early, on the bench, instead of in your production line. If you suspect a component is on the edge, call 832-729-9906 and we'll inspect it before it fails.
