Aerol is a trusted engineering partner with over seven decades of experience in delivering reliable mobility and ground support solutions for mission-critical applications.

It designs application-specific high-performance casters, running gear and ground support equipment with end-users in mind. A deep understanding of complex operational needs allows it to support various clients, including Department of Defense (DoD) engineering depots, military prime contractors and commercial aerospace and space exploration leaders like United Launch Alliance and Blue Origin.

Aerol’s strength lies in its deep vertical integration, made possible by its parent organization, Caster Concepts, comprising ten U.S.-based business units specializing in unique capabilities. This tightly connected structure enables Aerol to leverage in-house expertise to reduce lead times and develop distinct, custom-built solutions that others can’t match.

“Our strength lies in being able to tailor our solutions like an à la carte menu—mixing proven components to meet precise requirements with speed and precision,” says Alex Harden, technical product manager.

For instance, its sister company, Conceptual Innovations, plays a key role in integrating Aerol’s solutions with advanced technologies like automated systems and automated guided vehicles. From fabrication and machining to in-house polyurethane processing, every stage of production is handled internally, ensuring complete control and accelerated turnaround.

Aerol’s ability to deliver reliable, high-performance equipment is powered by a streamlined process that begins with a strong focus on engineering and quality standards. Its in-house engineering team includes experts in mechanical, electrical and hydraulic design. As a certified AS9100D supplier, it follows rigorous processes and meets demanding military specifications.

This commitment to engineering excellence is best reflected in its collaboration with an engineering depot in Lakehurst, New Jersey, on a maintenance dolly for the CH-53K helicopter. Over nine months, Aerol worked closely with the depot’s design engineer to adapt its proprietary version of a conventional running gear system. Due to the tool’s strict height and load specifications, standard components alone weren’t sufficient. Aerol integrated custom-manufactured hubs with F-16 front landing gear tires, procured separately by the DoD. This hybrid design allowed the dolly to meet structural requirements during operations when the landing gear is removed from the helicopter.

Another long-standing example is its collaboration with Lockheed Martin on the U-2 spy plane program—dating back nearly 70 years. Aerol was originally tasked with developing a rear landing wheel that could endure extreme speeds and temperatures. Using an aluminum core combined with its proprietary in-house polyurethane processing, it engineered a wheel capable of withstanding landing speeds of 140 mph. The wheel also delivers optimal performance in wide-ranging conditions, from extreme tarmac temperatures exceeding 120°F to -40°F at 70,000 feet.

Behind every success is a highly experienced and technically diverse team. As a mechanical engineer, Harden brings a strong technical understanding to each project, enabling him to easily grasp clients’ specific needs. He also actively engages the aerospace and DoD sectors to promote Aerol’s capabilities and educate key individuals and engineering groups about the company’s value and sector-specific experience and how its solutions align with mission objectives. With expertise spanning mechanical, electrical and hydraulic engineering, as well as advanced automation and design analysis, the team brings depth and versatility to every project.

Backed by deep industry expertise, it continues to deliver mission-critical applications that meet client requirements. For those seeking high-performance, precision-engineered solutions, Aerol remains a trustworthy destination.

Military Ground Support Equipment Built for Long-Service Readiness

Military aviation support infrastructure is under growing pressure to perform across longer service cycles, harsher deployment conditions and specialized aircraft programs. Ground support equipment once designed around standardized platforms now has to accommodate evolving airframes, transport constraints and maintenance environments across defense branches and aerospace programs. Procurement teams are no longer evaluating suppliers solely on product availability or scale. Greater attention is being placed on engineering collaboration, long-term maintainability and the ability to adapt proven systems to mission-specific requirements. That shift matters as defense organizations extend legacy aircraft lifecycles while introducing newer platforms with tighter dimensional tolerances, stricter mobility requirements and more complex servicing needs. Maintenance depots and aerospace engineering teams increasingly require suppliers capable of engaging early in the design process, before complete technical specifications are finalized. Manufacturers that contribute engineering insight during those stages can help reduce redesign cycles, procurement delays and maintenance complications. Customization has also become central to aerospace support procurement. Standardized equipment can create limitations when programs involve transport compatibility, unusual load distribution or environmental performance demands. Buyers value manufacturers that can modify existing platforms without compromising certification requirements or delivery timelines. Engineering depth matters because many aerospace support applications involve mechanical, hydraulic and electrical elements that must function together under controlled tolerances. Long-term reliability remains critical, particularly for defense applications where equipment may remain in service for decades. Products supporting military aircraft frequently operate across extreme climates, variable terrain and demanding transport conditions. Procurement leaders favor manufacturers with established quality systems, traceable manufacturing controls and direct experience supporting defense maintenance ecosystems. In-house manufacturing also carries weight because it allows tighter oversight of quality consistency, lead times and product modifications. Aerol operates through a model centered on engineering collaboration, vertically integrated manufacturing and decades of defense-sector specialization. Approximately seventy percent of its business supports Department of Defense programs, including engineering depots and maintenance organizations responsible for long-service military equipment. Its customer base also includes major aerospace and defense contractors alongside commercial aerospace and launch organizations. Its approach is built around early engagement with engineering teams to define application requirements before final equipment specifications are established. One recent example involved collaboration with a naval engineering depot developing a maintenance dolly for the CH-53K helicopter. The project required a customized running gear system capable of meeting strict height limitations while supporting transport inside military cargo aircraft. Aerol combined its existing running gear platform with specialized wheel configurations and in-house manufactured components to satisfy both load and dimensional requirements. Its long-standing relationship with Lockheed Martin’s U-2 aircraft program reflects another dimension of its specialization. Aerol developed a wheel system capable of handling extreme speed, temperature and load conditions uncommon in conventional polyurethane applications. The product remains in service decades after introduction, supporting aircraft operating across severe environmental ranges. Aerol’s advantage is reinforced by its vertically integrated manufacturing structure across multiple affiliated business units in Michigan. Fabrication, machining and polyurethane processing are handled internally, giving it greater control over lead times, quality verification and custom development. Its engineering teams include mechanical, hydraulic and electrical specialists capable of integrating newer automated technologies alongside traditional aerospace support systems. For defense and aerospace organizations managing specialized fleets and demanding maintenance environments, Aerol stands out as a manufacturer equipped to support legacy reliability and evolving program requirements. ...Read more
