## 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

Right-angle conveyor drives, material handling, and space-limited machinery.

## Subseries and Public Specification Matrix

### B bevel-helical right-angle gearbox

Scope: Heavy right-angle bevel-helical reducers for conveyors, kiln drives, bucket elevators, and crushers.

Public specs to check:
- torque 3,600-1,400,000 Nm
- ratio 5-400
- right-angle shaft layout

Buyer use: Use this family when the machine layout requires a Flender or SEW-style bevel-helical replacement.

### Right-angle conveyor and hoist package

Scope: B-series drive packages with accessory, lubrication, thermal, and installation-side review.

Public specs to check:
- fan or cooling option
- backstop direction
- mounting side and shaft orientation

Buyer use: Use this family when installation orientation and accessory position decide replacement fit.

### Space-limited retrofit package

Scope: Right-angle replacement reviews for legacy machines with fixed foundation, guard, and shaft constraints.

Public specs to check:
- foundation footprint match
- shaft height and overhang
- oil fill and drain clearance

Buyer use: Use this family when changing the surrounding machine frame is not practical.

## Minimum Inputs Before Matched Files

- Power, torque, and output speed
- Right-angle layout constraints
- Shaft orientation
- Mounting and service factor

## CAD and Datasheet Release Gate

Released after right-angle layout review.

Engineering confirms shaft orientation, right-angle clearance, load factor, and mounting before CAD release.

## Matched Package After Review

- Right-angle gearbox envelope
- Shaft orientation drawing
- Accessory notes
- Packing 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.
