32P Mechanical Interface

Controlled drawing code: SG01PD32 v1.0

Status: Approved for Public
Configuration represented by current CAD: 4-stage reference
Release date: 2026-09-28

This page contains the interface information normally required for packaging, mounting and early design-in.

Warning

The current public STEP represents the 4-stage reference only. It must not be treated as a universal 1-4 stage model. Request controlled CAD for the selected stage before final tooling or production release.

Stage-Dependent Body Length

Stages Gearbox body length L
1 28.05 mm
2 36.35 mm
3 44.65 mm
4 52.95 mm

4-Stage External Envelope

Item Public value
Nominal gearbox outer diameter 32 mm
Gearbox body length 52.95 mm
Output shaft extension 21.6 mm (+0.1 / -0.3 mm)
Nominal overall length including output shaft 74.55 mm

The 74.55 mm overall value is derived from the published 52.95 mm body length plus the 21.6 mm output shaft extension.

Output-Side Interface

  • 4 x M3 threaded holes, depth 4.5 mm
  • Mounting-hole center radius: 9.8 mm
  • Output-side reference diameter: 26.0 +/- 0.1 mm
  • Nominal output shaft diameter: 8 mm
  • Keyway width shown: 3.0 mm
  • Keyway length shown: 12.0 mm
  • Controlled drawing references DIN 6885-A3X3X3

The simplified public STEP uses nominal cylindrical thread envelopes and does not reproduce the detailed thread form or complete keyseat geometry.

Input / Motor-Side Interface

  • 2 x dia. 3.1 mm mounting holes
  • Opposed mounting-hole center spacing: 22.0 +/- 0.1 mm
  • Central input opening: dia. 13.0 +0.05 / 0 mm

The exact motor locating-bore tolerance remains controlled by the production drawing and should be confirmed for the selected motor.

The public STEP retains:

  • 32 mm external gearbox envelope
  • 4-stage body length
  • output shaft envelope
  • output mounting interface
  • input central opening
  • input mounting-hole pattern

It intentionally omits:

  • internal planet gears
  • sun gear and ring gear detail
  • internal carrier geometry
  • bearings
  • internal fasteners
  • manufacturing-only internal geometry

Final Design Release

Before final tooling or production release, confirm:

  • selected ratio and stage count
  • controlled drawing for that configuration
  • motor shaft and locating interface
  • output key / keyseat definition
  • mounting tolerances
  • radial and axial load direction
  • duty cycle and thermal condition

Controlled Full-Assembly CAD Status

A detailed 32P full-assembly STEP has also been reviewed internally. It contains internal planetary transmission geometry and remains configuration-controlled / request-only.

The existing public 4-stage STEP remains the approved simplified external-interface model for early packaging and design-in.
