Why Source Refurbished FANUC Motors From Us?

Rigorous Dynamic Test-Bench Run: Industrial motors cannot be verified with simple static resistance meters alone. Every A06B-0115-B855#0048 unit we prepare undergoes a strict dynamic run checkout hooked up to live FANUC drive amplifiers. We test the motor up to its rated RPM limits, scrutinize vibration amplitudes, measure current draw under physical brake resistance, and double-check optical feedback telemetry to ensure perfect out-of-the-box reliability.
Premium Insulation & Bearing Overhaul: Industrial environments subject motors to constant ambient metallic dust and heavy moisture. Our refurbishment cycle includes an extensive megger-insulation leakage test of the stator windings and a mechanical bearing integrity check. Any worn or noisy bearings are replaced with premium industrial-grade components to guarantee quiet, friction-free performance.
Flawless Drop-In Physical Alignment: Engineered strictly to original FANUC factory flange geometry, mounting bolt spacing, and shaft diameter tolerances under the specific output blueprint. Your team can complete a clean direct physical swap—unmount the burnt or locked motor, slip our replacement unit into the gearbox or coupling sleeve, and lock it down with standard fasteners without modifying structural linkages.
Beat Extensive OEM Factory Backlogs: When a primary servo motor shorts out, a critical workcell bricks completely, generating thousands of dollars in cumulative downtime losses. Sourcing our certified pre-owned units provides an instant, budget-friendly alternative to premium OEM pricing and multi-week manufacturer lead times, allowing your plant to resume operational cycles swiftly.
