Planetary gearbox, 80 mm, 32:1 reduction
This Schneider Electric GBX0800321404F is a planetary gearbox with straight teeth, 80 mm housing diameter, and a 32:1 reduction ratio. It delivers a continuous output torque of 120 N.m at 100 rpm and 30 °C, with a maximum torque of 192 N.m under the same conditions. Efficiency is listed at 94 %, and the noise level at 60 dB measured 1 m away under no-load — quiet enough for most production-floor environments without extra soundproofing.

Mechanical ratings and service life
Rated service life is 30,000 hours at 100 rpm and 30 °C. Maximum axial force is 1200 N for 10,000 hours or 900 N for the full 30,000-hour rating; maximum radial force is 950 N for 10,000 hours or 650 N for 30,000 hours, with force applied at mid-distance on the output shaft. Torsional backlash is 14 arc-minutes maximum — this matters for positioning accuracy in indexing or pick-and-place applications. The housing is black anodized aluminium with shaft output rated IP54, and the shaft material is C45 steel.
