Inline Planetary Gearheads
High-precision inline planetary gearheads for servo and stepper motor integration with low-backlash control.
Target Buyer:Best for OEM teams needing predictable servo response and clean mechanical packaging.
Capability Highlights
- Compact inline package for direct axis integration
- Low-backlash options for repeatability-sensitive motion
- Multi-ratio availability for torque-speed optimization
Typical Applications
- SCARA and articulated robot joints
- CNC feed and indexing modules
- Automated dispensing and packaging axes
Engineering Focus
- Inertia matching between motor, gearhead, and load
- Backlash target selection by application tolerance
- Thermal margin verification under duty cycle
Key Evaluation Matrix
| Metric | Typical Range | Why It Matters |
|---|---|---|
| Backlash Class | 3-15 arcmin | Backlash class directly affects positioning stability and vibration control. |
| Nominal Ratio | 3:1 to 100:1 | Ratio determines trade-off between output torque and achievable speed. |
Risk Controls
- Ratio selected from static torque only: Validate against full motion profile including acceleration and cycle time.
- Interface mismatch at assembly: Freeze shaft, flange, and pilot dimensions before prototype release.
Product Selection Worksheet
Use this worksheet in your internal review to convert assumptions into explicit RFQ inputs before supplier quotation.
| Decision Gate | Buyer Question | Evidence to Request | Release Condition |
|---|---|---|---|
| Backlash Class | Backlash class directly affects positioning stability and vibration control. | Target motor model and flange standard (NEMA or metric) | Risk control agreed: Validate against full motion profile including acceleration and cycle time. |
| Nominal Ratio | Ratio determines trade-off between output torque and achievable speed. | Required ratio, output torque, and max input speed | Risk control agreed: Freeze shaft, flange, and pilot dimensions before prototype release. |
Minimum first-email payload: motor model, load profile, target ratio range, acceptance threshold, and sample quantity timeline.
Sample-to-MP Handoff Checklist
- Freeze drawing and requirement baseline before sample release.
- Record pass/fail evidence for the same metrics used in quotation.
- Log all engineering changes with revision ownership on both sides.
- Approve mass-production release only after acceptance evidence and delivery milestones are aligned.

Buyer FAQ
Can you match inline gearheads to our existing motor platform?
Yes. We support NEMA and metric interface matching and can review motor drawings before quotation.
Do you support low-backlash variants for precision axes?
Yes. Low-backlash classes are available with trade-off guidance on cost and lead time.
