## 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

SCARA joints, cable-through rotary axes, and compact robot tooling.

## Subseries and Public Specification Matrix

### Cable-through joint reducer

Scope: Hollow-bore strain-wave, cycloidal, or planetary reducers for robot joints and rotary end-effectors.

Public specs to check:
- central bore clearance
- ratio 30:1-160:1
- low-backlash target

Buyer use: Use this family when cables, air lines, or slip-ring routing must pass through the gearbox centerline.

### Hollow rotary table gearbox

Scope: Large-bore indexing and rotary table drives with moment-load and runout checks.

Public specs to check:
- moment-load capacity
- output runout review
- large bore diameter

Buyer use: Use this family for fixtures, turntables, and inspection cells that need cable access and rigid support.

### AGV steering hollow-shaft gearbox

Scope: Compact hollow-shaft steering reducers for AMR and AGV wheel module integration.

Public specs to check:
- steering angle clearance
- sealed compact housing
- wheel-module bolt pattern

Buyer use: Use this family when the drive module combines steering, braking, and wiring through a tight central package.

## Minimum Inputs Before Matched Files

- Hollow bore diameter
- Cable or pneumatic pass-through need
- Output flange pattern
- Ratio and backlash target

## CAD and Datasheet Release Gate

Released after bore and cable pass-through review.

Engineering confirms bore clearance, sealing, flange pattern, and output load before CAD package release.

## Matched Package After Review

- Hollow-bore envelope
- Output flange drawing
- Sealing and lubrication notes
- Inspection checklist

## 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.
