Lightweight and torque-dense cycloidal reducers for End-of-Arm Tooling (EOAT), grippers, and robotic welding positioners.
| Evaluation Metric | Typical Range | Buyer Relevance |
|---|---|---|
| Torque-to-weight ratio | Optimized for minimal payload penalty | Every gram at the end of the arm reduces the effective payload of the primary robot. |
| Tool engagement shock | Peak event torque from clamping, welding, or impact | EOAT reducers often fail on transient loads that are not visible in average cycle torque. |
| Decision Point | Choose When | Verify Before Quote | Next Internal Step |
|---|---|---|---|
| Torque-to-weight ratio is the first sourcing filter | Best for robot integrators and EOAT builders needing compact torque at the end of the arm. Use this path when torque-to-weight ratio (Optimized for minimal payload penalty) is more important than starting from a generic gearbox size. | Every gram at the end of the arm reduces the effective payload of the primary robot. Include maximum allowable reducer weight in the first RFQ packet. | Compare Application Solutions |
| Mechanical interface risk is visible early | Minimize reducer weight to preserve primary robot payload. | Tool crash damage: Size the reducer against the emergency stop and impact torque limits, not just the operating torque. | Send RFQ Package |
| Sample acceptance must be measurable | Use prototype planning when tool engagement shock must be confirmed against buyer-side machine tests. | Payload capacity loss: Compare reducer weight, tool mass, and center of gravity against the robot payload chart. | Plan Prototype Validation |
| Phase | Engineering / QC Checkpoint | Buyer Output |
|---|---|---|
| Requirement baseline | Maximum allowable reducer weight; Peak torque during tool engagement. Confirm drawing revision, quantity, destination, and timeline in the same packet. | A quote-ready RFQ sheet that separates required performance from preferred options. |
| Engineering fit review | Minimize reducer weight to preserve primary robot payload. Evaluate cable routing options (hollow shaft vs solid). Record open issues before sample cost and lead time are frozen. | A reducer shortlist and issue log for EOAT Cycloidal Reducer. |
| Prototype or incoming validation | Measure torque-to-weight ratio and tool engagement shock against the agreed method. Size the reducer against the emergency stop and impact torque limits, not just the operating torque. | Inspection and test evidence with pass/fail limits, measured values, and revision actions. |
| Batch control and export readiness | Payload capacity loss: tie the control plan to outgoing inspection, packaging, labeling, and shipment records. | Repeat-order package covering drawing baseline, CTQ records, packaging rules, forecast, and Incoterm. |

CAD / STEP Data Pack
Use this application package request when your team needs a model file, envelope drawing, or engineering data before committing layout space. We verify the target family, revision, and release constraints first so buyers do not design around the wrong CAD file.
Confirm released model files, closest reference family, and file-release constraints before CAD freeze.
Align motor pilot, output flange, hollow bore, cable route, bolt circle, and axial envelope early.
Request backlash method, run-in note, inspection fields, and sample acceptance data for the selected family.
Inquiry Email
Best for sending NDA terms, drawings, or a specification sheet.
Instant Chat
+8618857971991
Best for quick model availability and file-release checks.
Submit the minimum engineering context needed for model-file screening and revision-safe follow-up.
Application RFQ
Include the machine module, duty profile, ratio, torque, backlash, interface limits, and validation plan so engineering can respond against the real application risk.
Yes, hollow bore configurations are commonly used in EOAT to route pneumatics and sensor cables through the center of rotation.
Weight, center of gravity, cable or air routing, crash torque, and tool-change envelope matter as much as nominal torque.
Program Route
EOAT Cycloidal Reducer defines the use-case risk. The next step is to connect it to the reducer family, drawing request, DFM review, and validation records.
Check reducer architecture, model family, envelope class, and CAD availability before the quote is treated as final.
Review the machine or robot axis context so torque, shock, backlash, stiffness, and validation risk stay tied to real use.
Move from fit review into DFM, sample validation, inspection records, packaging, and repeat-order control.
Use these links when the buyer is ready to send requirements, compare directories, or review sourcing guidance.
Inquiry Email
Include ratio, torque, backlash, interface drawings, quantity plan, and destination terms.
