## 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

Welding robots, palletizing axes, positioners, and high-load automation.

## Subseries and Public Specification Matrix

### Base and waist axis reducer

Scope: Large robot base, waist, and rotary positioner axes that need torsional stiffness and impact tolerance.

Public specs to check:
- high torsional rigidity
- shock-load review
- large output flange support

Buyer use: Use this family when the axis carries high overturning moment or welded fixture loads.

### Arm and wrist axis reducer

Scope: Medium and compact robot arm axes where backlash stability and inertia control define motion quality.

Public specs to check:
- low backlash under repeat load
- compact axial length
- servo inertia match

Buyer use: Use this family for welding, palletizing, handling, and polishing robot joints with repeatability targets.

### External axis gearbox

Scope: Seventh-axis, positioner, and robot cell auxiliary axes with long duty-cycle requirements.

Public specs to check:
- bearing support review
- sealed output options
- thermal and duty-cycle check

Buyer use: Use this family when a robot cell needs synchronized auxiliary motion with heavier payloads.

## Minimum Inputs Before Matched Files

- Rated and shock torque
- Radial and axial load
- Robot axis position
- Lubrication and mounting angle

## CAD and Datasheet Release Gate

Released after load case review.

Engineering validates overload factor, bearing load, installation angle, and housing interface before sending files.

## Matched Package After Review

- Load review notes
- 3D installation envelope
- Interface drawing
- Run-in and inspection 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.
