Gimbal Structures

Camera gimbals: pivot bearing seats concentric to ≤ 0.005 mm. All three axis bearing seats must be perpendicular to each other within ≤ 0.01 mm/100 mm. This ensures the optical axis passes through a stable centre of rotation — critical for stabilisation accuracy. These tolerances are verified by CMM and reported.

HXC uses symmetrical pocket milling — removing material from the inner surfaces of the gimbal yokes while retaining full wall thickness at bearing seat zones, motor mounts, and structural ribs. This typically reduces frame weight by 40–55% while retaining 95%+ of the torsional stiffness needed for stabilisation.

HXC machines gimbal motor mounts for all standard brushless gimbal motors: hollow-shaft motors (custom bore and flange), standard stator bolt patterns, and direct-drive mounting faces. Provide the motor datasheet and we machine to the manufacturer's interface specification.

Yes — inner, middle, and outer yoke frames are produced and CMM-verified as a matched set. All bearing seat positions are verified relative to a common reference to confirm the three pivot axes are orthogonal and pass through the nominal intersection point.

Al 7075-T6 hard anodized: standard for most UAV camera gimbals — 2.81 g/cm³, high stiffness, non-reflective black anodized finish suppresses stray reflections. Al 6061: lower cost, adequate strength for lightweight camera gimbals. Ti Grade 5: for defence, marine, and demanding environments where higher specific stiffness is needed.

Type III hard anodized black (15–25 µm, HV 400+): non-reflective, wear-resistant, and corrosion-resistant. The black finish also reduces stray light reflections into the camera sensor. Dimensional pre-compensation is applied before anodizing.

Yes — for high-altitude and low-temperature environments (−40°C to −60°C operating range), HXC recommends: Al 7075-T651 (better toughness at low temperature than T6); Type III anodizing (enhanced environmental protection); Alodine 1200 conversion coating at bond interfaces.
