Hollow-Shaft Joint Actuators

Hollow-shaft humanoid joint actuators for cable-through routing, compact wiring, and cleaner multi-axis integration inside arms, wrists, ankles, and torso modules.

Target Buyer:For robotics teams whose main integration problem is routing cables through a rotating joint without adding external cable loops.

Hollow shaft humanoid joint actuator for cable-through routing

Capability Highlights

Hollow bore actuator options for wiring, pneumatic tubes, and sensor cables
Compact joint packaging support for integrated humanoid arms and legs
Interface review around flange, bearing support, cable exit, and connector location

Typical Applications

Humanoid wrist and elbow joints
Cable-through ankle and shoulder joints
Compact torso and neck actuator assemblies

Engineering Focus

Hollow bore diameter, cable bundle bend radius, and connector packaging
Output flange datum, bearing load, and robot joint structure
Sealing, dust protection, and serviceability around the rotating cable path

Key Evaluation Matrix

Metric	Typical Range	Why It Matters
Through-hole diameter	Model dependent	Cable-through routing is the main reason to select a hollow-shaft actuator.
Axial length	Reducer, motor, encoder, and brake dependent	Humanoid joints often fail packaging reviews because a module is too long after connectors are included.

RFQ Checklist

Required through-hole diameter and cable bundle details
Output torque, speed, axial length, outer diameter, and mounting pattern
Cable exit direction, connector requirement, and harness length
Bearing load assumptions and whether external support bearings are used
Sample quantity and target robot joint position

Risk Controls

Cable bundle fits the bore but violates bend radius at the joint exit: Review cable path in 3D and include connector body, strain relief, and service loop assumptions.
Through-hole requirement forces an oversized actuator: Compare cable-through, side-exit, and split-harness designs before fixing the bore size.

Buyer FAQ

Can hollow-shaft actuators be customized?

Interface customization may be possible after a standard baseline model is selected. Bore diameter, flange, and cable exit changes need early DFM review.
