High-reliability electromechanical actuators replacing hydraulic systems.
Aerospace mechanisms need the screw decision to include documentation, vibration, temperature, lubrication, and supplier qualification evidence from the start. Inverted and high-stiffness roller screws are relevant when hydraulic replacement, compact EMA packaging, or flight-control load density are the primary constraints.
Send AS9100 or customer-specific flowdowns, MTC requirements, inspection records, and packaging constraints with the RFQ.
Risk if missed: A technically workable part can fail supplier qualification if documentation scope is defined after quotation.
Include temperature cycles, vibration profile, shock assumptions, lubricant restrictions, and storage conditions.
Risk if missed: Material, clearance, and lubrication choices can change when environment is added late.
Define whether the screw is flight-critical, ground support, test equipment, or non-critical payload mechanism.
Risk if missed: Acceptance criteria and inspection level differ sharply by criticality.
| Evaluation Metric | Typical Range | Buyer Relevance |
|---|---|---|
| Quality Standard | Customer flowdowns, MTC, inspection records | Required evidence depends on criticality, buyer approval path, and qualification scope. |
| Capability | Evidence | Buyer Value |
|---|---|---|
| Traceable aerospace material control | EN 10204 3.1 material certificate, heat-treatment record, hardness report, and lot traceability. | Gives procurement and quality teams the documents needed for supplier onboarding. |
| Precision inspection package | CMM report, lead accuracy trace, surface finish record, and final dimensional inspection. | Supports incoming inspection and first-article review without relying on visual acceptance. |
| EMA architecture review | Sizing notes covering load, life, vibration, bearing support, and packaging constraints. | Helps aerospace teams compare roller screw fit against hydraulic or ball-screw alternatives. |
Step 1
Documentation matrix for material, heat treatment, inspection, packaging, and customer flowdowns.
Acceptance: Buyer quality team confirms required records are included before sample PO.
Step 2
Sample part with dimensional report, material record, hardness report, and lead accuracy evidence.
Acceptance: First article passes buyer inspection and environmental test planning.
Step 3
Repeat-lot control plan, inspection frequency, and deviation handling path.
Acceptance: Supplier quality approves process control for the intended mechanism class.
Yes. EN 10204 3.1 material certificates and lot traceability can be included when the RFQ defines the required alloy, heat-treatment route, and inspection scope.
Yes. We review load path, support bearings, vibration profile, temperature range, and documentation flowdowns before recommending a screw architecture.
