Hollow Shaft Robotized Gearbox
Hollow-shaft gearbox options for automation axes that need cable, tube, or sensor routing through the reducer center while maintaining compact machine architecture.
Target Buyer:Design engineers who need a compact reducer without blocking cables, hoses, or sensors through the rotation axis.
Capability Highlights
- Large through-bore options for integrated robot and automation designs
- Cable and pneumatic routing support for compact assemblies
- Interface review for hollow-bore diameter, flange, and sealing constraints
Typical Applications
- Robot wrist and rotary modules
- Hollow rotary tables
- AGV steering modules
- Compact automation cells with internal cable routing
Engineering Focus
- Through-bore diameter and usable clearance
- Bearing arrangement, output flange, and moment load
- Cable bend radius and contamination protection
- Backlash and rigidity under hollow-shaft geometry constraints
Key Evaluation Matrix
| Metric | Typical Range | Why It Matters |
|---|---|---|
| Through-bore diameter | Small cable bore to large hollow shaft | The bore defines whether cables, air tubes, or sensor harnesses can pass through safely. |
| Moment load capacity | Application-specific | Hollow modules often carry offset loads that must not overload the output bearing system. |

Subseries and Specification Coverage
Use this matrix to identify the right engineering review path before requesting model-specific CAD, drawings, or a drop-in replacement check.
| Subseries | Scope | Public Specs to Check | Buyer Use |
|---|---|---|---|
| Cable-through joint reducer | Hollow-bore strain-wave, cycloidal, or planetary reducers for robot joints and rotary end-effectors. |
| Use this family when cables, air lines, or slip-ring routing must pass through the gearbox centerline. |
| Hollow rotary table gearbox | Large-bore indexing and rotary table drives with moment-load and runout checks. |
| Use this family for fixtures, turntables, and inspection cells that need cable access and rigid support. |
| AGV steering hollow-shaft gearbox | Compact hollow-shaft steering reducers for AMR and AGV wheel module integration. |
| Use this family when the drive module combines steering, braking, and wiring through a tight central package. |
Risk Controls
- Clear bore exists but cable routing is unsafe: Review cable bundle diameter, bend radius, rotation angle, and abrasion protection.
- Hollow gearbox selected without bearing load review: Validate radial, axial, and moment load before sample approval.

Buyer FAQ
Can hollow-shaft gearboxes support pneumatic or electrical routing?
Yes. The first step is to confirm actual cable or tube bundle size, required rotation angle, and environmental protection.
Are hollow-shaft gearboxes always more expensive?
They usually cost more than solid-shaft units, but they can reduce assembly complexity and make the full machine design cheaper.
