Side elevation of the GS37 gearhead at its shortest published ratio, 6:1 over 2 stages, drawn to scale from ⌀37.0 mm by 19.0 mm. Length grows with stage count; every ratio's own length is in the table below.

Every published ratio

Length, rated output torque and typical efficiency change with the stage count. The bore, the mounting face and the diameter do not.
