Rexnord Aerospace

What Rexnord Aerospace does

Rexnord Aerospace is the aerospace division of Regal Rexnord Corporation (NYSE: RRX), operating under the brand "Regal Rexnord Aerospace Solutions" and headquartered in Downers Grove, United States. It supplies a broad portfolio of flight-critical and mission-critical components and integrated subsystems, including bearings, ball and lead screws, clutches and brakes, gearing, linear solutions, machinable liner, magnetics, motors, seals, feedback devices, and electro-mechanical actuation (EMA). The company serves aerospace and defense manufacturers across commercial airliners, fixed-wing military aircraft, business jets, helicopters, and emerging Advanced Air Mobility (AAM) and eVTOL platforms, and is leveraging retained sub-brands including Kollmorgen, Portescap, Delevan, and Nook/Thomson to address motion control requirements in those segments.

The business operates across 12 AS9100-certified global design and manufacturing sites, including a facility in Chihuahua, Mexico that achieved AS9100 certification on January 30, 2025. The company's technical differentiation centers on vertically integrated subsystems, exemplified by its EMA platform, which combines motors, gearing, ball screws, feedback devices, and engineering services from the in-house portfolio rather than sourcing discrete components from multiple suppliers. An enterprise field sales motion with collaborative design engagement is the primary go-to-market, with prices quoted by specification and application. Product positioning emphasizes 75+ years of aerospace experience and an installed base on nearly every commercial airliner and fixed-wing military aircraft in operation today.

Revenue is generated through direct hardware sales of components and integrated subsystems to aerospace and defense manufacturers; specific revenue and pricing are not publicly disclosed and are consolidated within publicly traded Regal Rexnord Corporation (NYSE: RRX). The company is actively investing in next-generation AAM and eVTOL platforms through a multi-year collaboration with Honeywell and through dedicated product launches targeting those platforms, while also serving adjacent land, sea, and space vehicle applications using its existing motion control portfolio.
