Airex

What Airex does

Airex is a U.S.-based precision electromagnetic components manufacturer, founded in 1961 (with company materials citing approximately 70 years of experience) and currently operating as a wholly-owned subsidiary of Allied Motion Technologies, rebranded as Allient (NASDAQ: ALLT), since 2018. The company designs and manufactures linear servo motors (I-Series iron core and C/P-Series ironless), rotary motors, voice coil actuators, and magnetic bearings, alongside custom electromagnetic devices such as resolvers, synchros, transformers, and torque motors. Its core technical differentiation rests on patented CNC-based robotic winding machines designed in-house, patented low-inductance coil designs, toothless iron-core technology, and patented magnetic bearing architectures (Lorentz and Maxwell), enabling claimed performance metrics including a 0.2 ms motor time constant and nanometer-level positioning precision for semiconductor lithography and wafer processing applications.

The company operates a B2B, sales-led enterprise motion model in which most engagements begin with engineering consultation and specification, followed by quote-based, custom configuration and multi-year supply into customer programs. Pricing is not publicly disclosed; products are sold to specification through Allied Motion's quote request system and direct field sales. End markets served include aerospace and space, military and defense, semiconductor equipment, medical devices, and life sciences/solar/photonics, with named program wins at Honeywell, Lockheed Martin, Draper Laboratory, General Dynamics, NASA, the US military, Apple (iPad manufacturing), Quartus, NIST, and KRISS. Manufacturing is led from a Tulsa, Oklahoma facility certified to AS9100 and ISO 9001, with ITAR compliance supporting defense export controls.

Revenue is not disclosed publicly, and headcount is in the 11-50 range, consistent with a specialty component supplier rather than a high-volume manufacturer. The company lists engineering/design services and contract manufacturing as add-on revenue streams. Strategic posture is anchored on long-cycle defense and aerospace qualification programs, complemented by selective commercial entries (semiconductor precision, Apple iPad production) and international product launches (C10/C16).
