Humanoid Robot Joint Housings: Product Overview
A humanoid robot joint housing is the precision structural body around an actuated joint.
Bore diameter, roundness, and concentricity determine preload, friction, stiffness, and alignment.
- Bearing-bore precision as a core competencyH6/J6/K6 bores can reach ±0.002mm diameter, ±0.001mm roundness, and ±0.003mm bore-to-bore concentricity.
- Lightweight housing design and mass disciplinePocket-optimised 7075-T6 and AZ91D housings use ultrasonic wall mapping to ±0.050mm and mass verification to ±0.5g.
- Single-setup bore concentricity preservationSequential boring can introduce 0.010–0.030mm re-registration error and excess friction.
- Finger-to-hip joint housing coverageOne qualified relationship supports all joint sizes with consistent bore inspection, material traceability, mass verification, and IATF 16949/AS9100D documentation.
Why CNCPioneer for Humanoid Robot Joint Housings?
Coordinate geometry, material, finishing and inspection around the part's intended function.
Lightweight Housing Design & Mass Discipline
Topology-optimised 7075-T6 and AZ91D housings use ultrasonic wall mapping to ±0.050mm and mass verification to ±0.5g per housing, or ±0.1g for hand joints .
Custom Humanoid Robot Joint Housing Development
Every enquiry receives a 24-hour DFM review covering bearing fit and anodise allowance, concentricity routing, thin-wall clamping, CAD mass checks, interface locations, and five-axis access.
Complete Joint-Type Portfolio
Review mounting faces, pockets and wall thickness and functional requirements before defining the process.
Single-Setup Bore Concentricity Preservation
Rechucking can add 0.010–0.030mm error and increase joint friction.
Prototype-to-Production Support in China
Support extends from drawing review and prototypes through PPAP Level 3 or repeat production, with coordinated inspection records, material certificates, mass verification, and delivery planning.

Explore representative configurations and share your drawing for a product-specific review.
Finger & Hand Joint Housings
MCP, PIP, DIP, and thumb CMC housings use Ø4–15mm bearing bores, 1.0–2.5mm walls, and 2–8g mass targets.
Wrist Joint Housings
Two- and three-DOF wrist housings combine Ø20–40mm primary bores with secondary axes held to ±0.003mm concentricity and ±0.02° orientation.
Elbow & Shoulder Joint Housings
Elbow housings use Ø30–60mm bearing bores to ±0.002mm and ±0.003mm concentricity, with cable passages and flange faces controlled to the bore axis.
