Humanoid robot leg U-brackets are high-load structural connectors that link hip, knee and ankle joints to actuators, reducers and lower-limb frames. Machined from aerospace-grade 7075-T6 or 6061-T6 aluminum (or TC4 titanium), they deliver the strength-to-weight ratio and dimensional precision bipedal platforms demand.
We machine these brackets on 5-axis CNC centers in a single setup, holding bearing bores, joint holes and mounting faces concentric and square so actuators align without shimming. Precision hole systems, threaded mounts and stress-relieved radii are cut to your CAD, and every bracket is deburred and inspected with CMM reports and material certificates for full traceability.
Typical applications include humanoid and legged robot lower-limb structures, actuator and reducer mounting, and load-bearing joint frames — from single prototype sets to mass-production runs.
U-shaped brackets with undercuts, inclined faces and precision hole systems are machined in a single setup on 5-axis centers.
Bearing bores and joint mounting faces held to ±0.005 mm, verified with CMM reports on every batch.
7075-T6 aluminum and TC4 titanium options reduce leg weight while maintaining high load capacity for dynamic motion.
From aerospace-grade aluminum to medical-certified engineering plastics, our in-house CNC machining centers work a broad range of metals and plastics under one roof.
