RFQ Checklist
- Define required clear bore diameter and cable bundle size
- Send output flange, input motor, and mounting interface drawing
- State target ratio, torque, speed, backlash, and bearing load
- Describe environment and sealing requirement
Hollow-shaft gearbox options for automation axes that need cable, tube, or sensor routing through the reducer center while maintaining compact machine architecture.
| 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. |
Public Selection Matrix
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. |
RGB-HS
Engineering confirms bore clearance, sealing, flange pattern, and output load before CAD package release.

Released after bore and cable pass-through review.
STEP, IGES, SolidWorks, 2D PDF on request
Use the no-login worksheets before sending drawings or requesting model-specific CAD. They help engineering confirm torque, backlash, interface, inspection, and replacement assumptions for Hollow Shaft Robotized Gearbox.
Yes. The first step is to confirm actual cable or tube bundle size, required rotation angle, and environmental protection.
They usually cost more than solid-shaft units, but they can reduce assembly complexity and make the full machine design cheaper.
