If you’ve ever tried to source a replacement caster for aging military equipment, a legacy industrial cart, or a discontinued product line, you know the frustration. The original manufacturer is gone. The part number returns no results. The only option you can find is an OEM alternative that costs three times what it should and takes 16 weeks to arrive. There is another option — and it’s one that procurement officers, defense maintenance programs, and industrial operations managers are increasingly turning to: reverse engineering.
At IAO Industries, reverse engineering casters and wheels is one of our core capabilities. In this post we’ll explain exactly what the process involves, when it makes sense to pursue it, and how it can save your operation significant time and money.
What Is Caster Reverse Engineering?
Reverse engineering a caster or wheel means starting with an existing part — even a worn or damaged one — and working backward to produce a fully detailed technical specification that can be used to manufacture an equivalent or improved replacement. Rather than relying on the original manufacturer’s drawings or part numbers, our engineers analyze the physical part: its dimensions, materials, load ratings, wheel composition, mounting configuration, and performance characteristics.
The result is a newly manufactured caster that meets or exceeds the original specification — often at a significantly lower cost and with a faster lead time than tracking down an OEM source.

When Does Reverse Engineering Make Sense?
Not every caster procurement situation calls for reverse engineering. But there are specific circumstances where it becomes not just an option, but the smartest one available:
1. The Original Manufacturer Is Out of Business or Has Discontinued the Part
This is the most common trigger. Military equipment, in particular, often runs for decades — long after the original suppliers have changed ownership, been acquired, or stopped producing specific components. When a part number no longer returns results and no direct replacement exists, reverse engineering is frequently the only path to a cost-effective solution.
2. OEM Pricing Is Prohibitive
Even when an OEM source exists, the pricing can be unjustifiable — particularly for parts needed in volume. When a single supplier controls the market for a specific caster, they can price accordingly. Reverse engineering introduces competition into that equation and typically results in 20-40% cost savings compared to OEM pricing, sometimes more.
3. Lead Times Are Unacceptable
Government and defense supply chains cannot always absorb 12-20 week lead times for standard replacement parts. Reverse engineering, once the initial SAR process is complete, can establish a manufacturing pipeline that delivers parts in a fraction of that time — and keeps them readily available for future orders.
4. The Part Needs to Be Improved
Sometimes reverse engineering isn’t just about replacing what existed — it’s about making it better. If the original caster design had known performance issues, caused injuries, or simply wasn’t optimized for the actual operating environment, the reverse engineering process is an opportunity to correct those problems while producing the replacement.
5. You Need to Qualify a Second Source
Supply chain resilience is a growing priority across defense and industrial procurement. Relying on a single source for a critical component is a vulnerability. Reverse engineering can establish a qualified second source — giving procurement teams negotiating leverage and protection against supply disruptions.
How the IAO Industries Reverse Engineering Process Works
Our reverse engineering process is straightforward and designed to minimize disruption to your operation:
Step 1 — Part Analysis
We begin by receiving the existing part — even if it’s worn, damaged, or incomplete. Our engineers conduct a full dimensional and material analysis, documenting every specification needed to produce an accurate replacement.
Step 2 — Technical Documentation
We develop complete technical drawings and specifications for the part. This documentation forms the basis for both the Source Approval Request (SAR) process and ongoing manufacturing.
Step 3 — Source Approval Request (SAR) Submission
For government and defense applications, new parts must go through a SAR process before they can be used in military supply chains. IAO Industries handles this process on behalf of our clients — preparing and submitting the required documentation and managing the approval process through to completion.
Step 4 — Manufacturing and Delivery
Once approved, we manufacture your parts through our USA manufacturing partners. Initial orders are typically delivered within two weeks of approval, and ongoing availability is established so future orders can be fulfilled quickly without restarting the process.

The Cost Savings Are Real
The financial case for reverse engineering is strongest when you factor in the full cost of the alternative — not just the per-unit price of an OEM part, but the operational cost of downtime, the administrative burden of chasing discontinued parts, and the long-term risk of single-source dependency. When you add it all up, reverse engineering frequently delivers not just a lower unit cost, but a lower total cost of ownership for the parts program.
For government buyers, the savings are doubly valuable — not only does it reduce program costs, but establishing a qualified SDVOSB source like IAO Industries can also satisfy small business contracting goals simultaneously.
Is Reverse Engineering Right for Your Situation?
If you’re dealing with any of the following, it’s worth a conversation:
- A caster or wheel part number that returns no results or is listed as discontinued
- OEM pricing that seems out of line with the complexity of the part
- Lead times that are creating operational risk
- Aging military or industrial equipment with no clear replacement parts pipeline
- A desire to qualify a second source for a critical component
IAO Industries has over 23 years of experience in material handling and has successfully reverse engineered casters and wheels for military, aerospace, automotive, and heavy equipment clients. As a certified SDVOSB and minority-owned business, we are also a qualifying source for government set-aside procurement.
