Aerospace & Defense Actuator Roller Screws

High-reliability roller screw components for compact electromechanical actuators (EMA) in flight control, missile steering, landing gear, thrust vectoring, and satellite positioning systems.

Target Buyer:Aerospace OEMs, Tier-1 EMA integrators, and defense contractors replacing hydraulic actuators with compact electromechanical solutions that require full traceability and qualification documentation.

Solution Highlights

Zero-backlash preload options for load-reversal accuracy in flight control surfaces
Material traceability, heat-number records, and CoC packages aligned to AS9100 flow-down
Shock-load and vibration-resistant architecture validated to buyer-defined duty cycles
Compact inverted layout for tight actuator envelopes in wing, tail, and nacelle packages

Common Use Cases

Flight control surface actuators (aileron, elevator, rudder)
Missile fin and thrust-vector steering
Landing gear retraction and extension EMA
Satellite antenna and solar panel positioning
Weapons bay door and stores-release mechanisms

Implementation Focus

Load/life calculation under combined axial, radial, and moment loads
Fail-safe, jam-tolerant, and anti-rotation design considerations
Environmental qualification: temperature cycling, altitude, vibration, salt fog
AS9100 / NADCAP flow-down, serialized traceability, and first-article inspection

Application Decision Notes

Typical module fit

Review this path for Flight control surface actuators (aileron, elevator, rudder), Missile fin and thrust-vector steering, Landing gear retraction and extension EMA, Satellite antenna and solar panel positioning, Weapons bay door and stores-release mechanisms where load density, stroke, and package length drive the screw architecture.

Validation gate

Agree on dynamic load capacity, backlash/preload, lead accuracy, and load-cycle evidence before sample approval.

RFQ routing

Include the target actuator envelope, application duty cycle, quantity stage, and preferred inspection documents in the first inquiry.

Application Evaluation Matrix

Evaluation Metric	Typical Range	Buyer Relevance
Dynamic Load Capacity	Up to 300+ kN (architecture-dependent)	Flight-control and landing-gear EMA demand high-cycle fatigue resistance under combined loading.
Operating Temperature	-54 °C to +125 °C (application-specific)	Lubricant selection, seal design, and preload stability must survive extreme thermal cycling.
Backlash Control	Zero-backlash preload, < 0.03 mm reversal	Load-reversal discontinuity in flight surfaces directly affects control-loop accuracy and safety.
L10 Fatigue Life	Mission-profile dependent, buyer-validated	Aerospace programs require traceable life evidence tied to flight hours, not generic catalog values.

RFQ Preparation Checklist

Actuator force, speed, stroke, and duty cycle profile
Environmental requirements: temperature range, vibration spectrum, altitude
Backlash/preload target and load-reversal test method
Required documentation: MTR, CoC, FAI, heat-treatment record, third-party test certs
Export control classification and delivery country

Risk and Mitigation

Single-point jam failure in flight-critical actuator: Review fail-safe architecture, anti-jam features, redundancy path, and test acceptance criteria during DFM.
Material or heat-treatment non-conformance undetected before assembly: Implement incoming material verification with heat-number traceability, hardness checks, and NDT where specified.
Qualification test failure due to preload drift at temperature extremes: Validate preload stability across the full temperature range with representative lubricant and sealing before sample approval.

Buyer FAQ

Do you support AS9100 documentation requirements?

Yes. Material traceability, serialized inspection records, heat-treatment certificates, FAI data, and CoC packages can be structured to align with AS9100 and buyer-specific flow-down requirements.

Can your roller screws replace hydraulic actuators in flight control?

Roller screw EMA assemblies are proven in flight-control, landing-gear, and missile-steering applications. Share your force, speed, stroke, and environmental requirements for a DFM review.

What is the maximum operating speed for aerospace roller screws?

Maximum speed depends on diameter, lead, lubrication, and critical-speed analysis. Provide your stroke, cycle rate, and acceleration profile for a specific recommendation.

How do you handle export-controlled or ITAR-restricted programs?

Confirm export classification and restriction scope during RFQ so documentation, shipping, and handling requirements can be reviewed before quotation.
