Regal Rexnord Aerospace Solutions, enabled by its family of leading brands—Rexnord Aerospace, Kollmorgen, Portescap, Nook, Thomson, Delevan, and Formsprag—is advancing the next generation of electro-mechanical actuators purpose-built for the unique requirements of aerospace and defense applications. This strategic, collaborative approach unites deep domain expertise and one of the industry’s most comprehensive motion control portfolios to deliver EMA solutions designed for optimal performance, efficiency, and operational versatility.
For more than 75 years, Regal Rexnord Aerospace Solutions has supported flight-critical commercial and military applications with precision engineering and leading-edge motion control technologies. The company’s expanded offering in subsystems leverages the unique strengths of its trusted portfolio, spanning high-performance motors, rotary and oscillatory bearings, dynamic seals, resolvers, magnetics, ball and lead screws, clutches, and brakes. By uniting these core technologies under a collaborative design model, Regal Rexnord Aerospace Solutions is positioned to deliver complete EMA subsystems designed and tested to the most rigorous standards for reliability in extreme environments.
“We’re seeing unprecedented acceleration in the shift from hydraulic to electric aircraft design. Nowhere is this growth more apparent than in the areas of advanced air mobility and electric vertical take-off and landing (eVTOL)”, said John Meyer, Senior Director of Marketing at Regal Rexnord Aerospace Solutions. “By consolidating our trusted technologies and collaborative engineering expertise, we’re able to provide complete, performance-optimized EMA subsystems that accelerate time to market, simplify supply chains, and prioritize uncompromising quality and reliability.”
Regal Rexnord Aerospace Solutions’ new EMA capabilities can offer customers these benefits:
- Seamless Vertical Integration: Solutions are designed and manufactured in-house at one or more of our 12 global AS9100-certified facilities, enabling accelerated transitions from prototyping to full-scale production.
- Performance-Optimized Design: Access to Regal Rexnord Aerospace Solutions’ comprehensive motion control building blocks streamlines engineering, enabling tailored actuator systems that are positioned to meet stringent aerospace and defense specifications.
- Supply Chain Simplification: EMA subsystems designed primarily with components from our Regal Rexnord Aerospace Solutions family of brands reduce the need to source and manage components from multiple suppliers, decreasing complexity and accelerating time to market.
- Reliability in Harsh Environments: Each system will undergo rigorous testing for compliance and durability, enabling mission-critical performance under extreme conditions of shock, vibration, and temperature.
- Collaborative Application Expertise: Regal Rexnord Aerospace Solutions’ engineering teams engage directly with customers to solve their most complex design challenges, rapidly adapting our proven technologies for unique application requirements across commercial aerospace, defense, and emerging sectors like advanced air mobility and eVTOL.
- Sustainable Design: Electro-mechanical actuation offers inherent benefits over traditional hydraulic solutions, enabling the conservation of resources through low-weight design, increased reliability, and longer lifetimes.
“We are proud to play a role in accelerating innovation in aircraft design,” said Kevin Zaba, Executive Vice President and President, Automation & Motion Control Segment, Regal Rexnord. “And we have a lot more to offer. This new EMA capability is just one example of the overall Regal Rexnord strategy for delivering exceptional value to customers through advanced solutions that enhance performance and promote sustainability. From aerospace to robotics to factory automation, we’re a strategic partner helping bring today’s most important innovations to life.”
