Keep Lines Running
When an automation cell is down, every minute counts. We help you find in-stock motion and maintenance parts by part number, confirm compatible replacements with cross-referencing, and ship fast so you can restore performance and keep production on schedule.
- Reduce downtime across automation cells and lines
- Find hard-to-identify parts with cross-references and interchanges
- Confirm specs, dimensions, and compatible equivalents
- Meet tight timelines with multiple shipping options

Parts & Systems We Supply for Robotics, Automation & Motion Control
When an automation cell or robot goes down, every minute of lost cycle time counts — and the servo drive, encoder, or controller you need is often obsolete or carries a long factory lead time. Central Surplus specializes in exactly these hard-to-find automation and motion-control parts, holding new and surplus stock of the drives, feedback devices, and precision motion components that keep robots, CNC machines, and automated lines running.
Categories we supply for automation include:
- Industrial Automation, Circuit Boards, and Power Supplies.
- Drives & Amplifiers for servo and spindle axes.
- Encoders and Sensors & Switches for position and process feedback.
- Linear Motion guides and Relays for actuation and control.
Brands Trusted in Automation & Motion Control
We carry the automation names that matter, including Fanuc, GE-Fanuc, Allen-Bradley, Siemens, Heidenhain, Beckhoff, Festo, SICK, Balluff, and IFM, plus precision linear brands THK and IKO.
Applications & Use Cases
Integrators, machine builders, and plant controls teams source servo amplifiers and drives, replacement encoders and resolvers, HMI and PLC boards, power supplies, and linear guides and bearings from our inventory. Typical jobs include restoring a robot after a servo fault, keeping a legacy CNC in production when the OEM has end-of-lifed a board, or building a spares kit for a critical automated line. Send us the model number and we will confirm stock and cross-references.
