DJI Matrice 400 Arm Connector Rotating Shaft Joint Mount

Replacement Arm Connector and Rotating Joint Mount for DJI Matrice 400

This replacement arm connector is intended for the DJI Matrice 400 folding arm/joint assembly. It is a structural repair component for enterprise operators maintaining aircraft affected by joint wear, impact damage or arm-connection issues.

Ares Acres is developing a U.S.-first Matrice 400 repair catalog focused not only on major payloads but also on the individual structural and mechanical components required to keep enterprise aircraft in service.

Compatibility

• DJI Matrice 400

Variant Structure

The supplier reference shows four distinct arm-connector orientations. This draft separates them as four tracked inventory variants. Exact aircraft position should be verified against the physical component before ordering or installation.

When This Part May Be Needed

• Arm-joint impact damage
• Cracked or deformed connector housing
• Abnormal play at the folding arm interface
• Damage discovered during post-impact inspection
• Structural repair requiring replacement of the connecting base or rotating shaft mount

Critical Repair Guidance

The arm connection is part of the aircraft's flight-critical structure. Replacement should be completed by a qualified technician using appropriate service procedures. After structural work, inspect adjoining components, wiring, fasteners, motor alignment and folding/locking behavior before returning the aircraft to flight.

Enterprise Applications

Matrice 400 aircraft may carry high-value thermal, LiDAR, mapping and multisensor payloads. Maintaining structural integrity is therefore especially important for fleets operating in inspection, surveying, public safety, infrastructure, construction, mining and agricultural remote-sensing environments.

Product Classification

The supplier describes this as an original Matrice 400 repair component, but no verifiable DJI material number is visible in the supplied reference. The title therefore avoids an unverified OEM claim pending provenance confirmation.
