Servo Drives

Shop surplus and used servo drives for CNC machines, robotics, and industrial automation. Trusted industrial brands, shipped nationwide from MRO Exchange in Illinois.

Used and surplus servo drives for sale. MRO Exchange stocks a continuously updated inventory of industrial servo drives available for immediate purchase and fast nationwide shipping.

Servo drives, also called servo amplifiers, are the power and control interface between a motion controller and a servo motor. They regulate current, voltage, and position feedback signals to deliver precise speed, torque, and positioning performance across CNC machining centers, lathes, grinders, multi-axis robots, and automated production lines. When a servo drive fails, production stops. Sourcing a surplus replacement is one of the fastest and most practical paths back to operation.

MRO Exchange carries surplus and used servo drives from leading industrial manufacturers including Fanuc, Siemens, and Mitsubishi. Our inventory spans a wide range of axis configurations, voltage ratings, and communication protocols including FSSB, PROFIBUS, and analog interfaces. Buying surplus is especially practical for older machines where new OEM servo drives are discontinued, on allocation, or priced well above the tested used market.

Who buys used servo drives? Maintenance and reliability technicians sourcing a critical spare to protect uptime. Machine rebuilders and retrofit specialists replacing drives on legacy CNC equipment. Controls integrators sourcing cost-effective components for customer projects. Facilities managers reducing capital spend on aging production equipment without sacrificing performance.

Are used servo drives reliable? Yes, when sourced from a seller who provides accurate condition grading and complete model documentation. MRO Exchange lists the manufacturer, model number, and condition for every drive in our inventory so buyers can verify compatibility before purchasing.

How do I know if a servo drive is compatible with my machine? Cross-reference the drive model number against your machine's electrical schematic or axis configuration documentation. When in doubt, consult your controls integrator or OEM service documentation before ordering.
