## Public File Status

Product-family brief and RFQ worksheet are public.

This public brief supports early RFQ screening and buyer-side engineering review. It is not a final model-specific datasheet, certified 2D drawing, STEP, IGES, or SolidWorks release.

## Best-Fit Use

High-payload robot arms, positioners, and heavy rotary axes.

## Subseries and Public Specification Matrix

### Cycloidal pinwheel RV reducer

Scope: Classic RV-style cycloidal pinwheel reducers for robot joints, positioners, and high-shock automation axes.

Public specs to check:
- high shock resistance
- high torsional rigidity
- low backlash under full load

Buyer use: Use this family when robot-axis stiffness and impact capacity are more important than lowest cost.

### Planetary gear type RV reducer

Scope: RV packages with planetary input distribution for compact servo matching and smooth torque transfer.

Public specs to check:
- planetary input stage
- servo adapter match
- thermal efficiency review

Buyer use: Use this family for robot arm axes where motor integration and package length are key constraints.

### Bearing type RV reducer

Scope: RV reducers with integrated output bearing support for moment loads and direct robot-joint mounting.

Public specs to check:
- integrated bearing format
- moment-load capacity
- output flange runout review

Buyer use: Use this family when the reducer also carries the axis output load.

## Minimum Inputs Before Matched Files

- Axis payload and moment load
- Ratio and cycle speed
- Input motor adapter
- Mounting side and lubrication position

## CAD and Datasheet Release Gate

Released after axis load and mounting review.

Engineering confirms load moment, mounting side, input adapter, and lubrication position before releasing the file set.

## Matched Package After Review

- RV reducer envelope
- Mounting and pilot drawing
- Load-screening notes
- Inspection document request list

## Buyer Review Notes

- Use this brief to decide whether the product family is plausible before sending confidential drawings.
- Attach torque, ratio, backlash, duty cycle, mounting, quantity, destination, and incumbent evidence when available.
- Ask engineering to confirm the configured model, interface, revision, and inspection-document scope before using any matched CAD file in a machine layout.
