6 Industrial Automation Parts Suppliers Worth Knowing in 2027

A failed drive or an obsolete PLC module rarely announces itself ahead of time. One day the line runs, the next day it doesn't, and whoever answers the phone first often decides how much the stoppage costs. Picking a parts supplier before that moment, rather than during it, is the difference between a short delay and a long one.

The market for automation and control parts splits roughly into two camps: generalists who stock huge catalogs across many categories and specialists who focus on repairs, refurbishment, or a narrower slice of components. Both have a place. The right fit depends on what's actually broken, how old it is, and how fast it needs to move.

6 Industrial Automation Parts Suppliers Worth Knowing in 2027

Best for Fast Worldwide Access to Tested Parts – EU Automation

EU Automation sources new, reconditioned, and obsolete automation and control components for businesses that can't afford an extended stoppage. The company delivers worldwide, which matters when a plant can't rely on one regional stockist for every part it might need.

The company holds ISO 9001:2015 certification, an internationally recognised quality management standard. Every unit is fully tested before dispatch and comes with a full 12-month return-to-base warranty, giving buyers added reassurance when sourcing reconditioned or hard-to-find parts. Next-day delivery is available on thousands of units, depending on location.

This is the kind of supplier an engineer calls when the part in question stopped being manufactured years ago, but the machine it belongs to is still running the night shift. For a plant manager comparing the costs of unplanned downtime against the price of keeping a reliable backup supplier on speed dial, that combination of testing, warranty coverage, and worldwide reach is the whole pitch.

Best for High-Volume Catalog Access – Radwell International

Radwell International stocks a large mix of new and surplus automation, electrica, and MRO parts, positioning itself around speed and uptime for customers who need a part now rather than next week. Its catalog depth suits maintenance teams who want one place to search across many part categories instead of several specialist vendors.

The trade-off shows up in customer sentiment. Radwell carries a 1.8 out of 5 rating on Trustpilot, a figure worth weighing against the convenience of its broad stock if service consistency matters as much as selection to your team.

Best for Repair and Refurbishment Services – Lektronix

Lektronix focuses on repairs rather than straight parts sales, offering free repair collection and a free repair quotation before any work begins. It operates as a Rockwell Automation Business, which shapes its focus toward fixing and refurbishing existing equipment rather than just shipping replacements.

Complete data retention on repairs and a mix of service exchange and refurbished parts make this a sensible call when a unit is worth restoring rather than replacing outright. Lektronix holds a 2.5 out of 5 rating on Trustpilot, based on a small number of reviews.

Best for Circular Refurbishment at Scale – JC-Electronics

JC-Electronics runs more than 300,000 products in stock, refurbishing HMIs, drives, PLCs and industrial PCs through what it describes as strict quality control processes. Repairs come with a 2-year warranty, and the company frames its model as 100% circular, meaning used components get a second working life instead of landfill.

That focus on refurbishment suits a business trying to extend equipment life or source a hard-to-find part from a recently retired machine. JC-Electronics holds a 4.5 out of 5 rating on Trustpilot, based on 296 reviews.

Best for Obsolete and Current Line Components – CJS Automation

CJS Automation specializes in both obsolete and current line components, holding thousands of parts in stock and ready to ship with fast worldwide delivery. The company positions itself around serving manufacturers globally rather than any single region or industry vertical.

That dual focus on legacy and current parts is useful when a facility runs a mix of older and newer equipment and doesn't want to juggle separate suppliers for each generation. CJS Automation holds a 4.5 out of 5 rating on Trustpilot, although its review count is relatively small.

Best for Combined Parts and Repair Work – Industrial Automation Co.

Industrial Automation Co. supplies new, surplus, and refurbished industrial automation parts alongside repair services. Its range includes drives, PLCs, HMIs and robotic components, while its in-house engineers handle refurbishment and technical support.

The company offers a two-year warranty on most parts and all repairs, making it worth considering for buyers who want replacement components and repair support from one supplier. Its focus on mature, legacy and end-of-life products also makes it relevant to businesses maintaining older equipment.

What actually separates these suppliers

Before picking a supplier, it helps to know which of three questions matters most for the part you're chasing. Is it still in production or genuinely obsolete? Does it need to be replaced outright or can it be repaired? And does your operation need one country's worth of coverage or global reach?

A single-region generalist with a huge catalog solves a different problem than a specialist who refurbishes legacy drives by hand. A supplier with thousands of reviews and a high average, like JC-Electronics' 4.7 on Trustpilot, says something different than one with only a handful of reviews, even if both ratings look similar on paper.

Warranty terms deserve the same scrutiny as price. A reconditioned part without any warranty backing is a bigger risk than a slightly pricier one that's fully tested and covered, especially on equipment that can't fail twice in the same month. Broader industry pressure toward automation adoption across manufacturing is only increasing how often these parts decisions come up, which makes a dependable sourcing relationship worth setting up before the next failure rather than during it.

Matching the supplier to the failure in front of you

None of these six companies are competing for the same job. Radwell suits a team that wants one enormous catalog to search first. Lektronix and JC-Electronics suit equipment worth repairing rather than replacing, with JC-Electronics carrying the stronger review base of the two. CJS Automation suits a plant juggling both legacy and current-line machines, and Industrial Automation Co. suits a buyer who wants parts and repair labor from the same vendor.

Supplier Best For Trustpilot Rating
EU Automation Fast worldwide access to tested parts —
Radwell International High-volume catalog access 1.8 / 5
Lektronix Repair and refurbishment services 2.5 / 5
JC-Electronics Circular refurbishment at scale 4.5 / 5
CJS Automation Obsolete and current line components 4.5 / 5
Industrial Automation Co. Combined parts and repair work —

For the specific problem of a critical part failing with no time to shop around, EU Automation's combination of worldwide delivery, full testing, and warranty coverage on every unit makes it the standout pick. When the question is simply how fast a tested, warrantied replacement can reach your floor, that's the strength that matters most.

✅
The Bottom Line

None of these six companies are competing for the same job. Matching the supplier to the specific failure in front of you — obsolete part, repairable unit, or critical downtime — is what turns a sourcing decision into a fast resolution.
