What this 32:1 planetary gearbox delivers
The GBX0600321403F is a straight-tooth planetary gearbox in a 60 mm diameter housing, delivering a 32:1 reduction ratio with 44 N.m continuous output torque at 100 rpm and 30 °C ambient. Maximum output torque reaches 70 N.m under the same conditions, with a torsional rigidity of 2.5 N.m/arcmin and maximum backlash of 20 arc.min. Rated service life is 30,000 hours at rated load, and the unit ships lubricated for life — no maintenance oil changes needed in service.
Sourcing an obsolete planetary drive
Schneider Electric lists this gearbox as Obsolete. Lot quantities vary; no stock-holding claim is made here. For a BOM line needing this exact reduction ratio and torque class, the GBX0600321403F remains orderable via surplus and broker channels. Confirm the mating motor flange and output shaft dimensions against your existing installation before committing.
Load ratings and thermal limits
Continuous output torque is 44 N.m at 100 rpm and 30 °C; maximum output torque is 70 N.m at the same speed and temperature — the 59 % headroom covers startup peaks and short-duration overloads. Maximum radial force Fr is 340 N at mid-span on the output shaft for the 30,000-hour life target, stepping to 500 N for a 10,000-hour duty cycle. Maximum axial force Fa is 450 N for the long-life case and 600 N for the shorter one. Operating ambient range is -25 to 90 °C; shaft output sealing is IP54 — suitable for indoor environments with dust and splash exposure but not pressure washdown.
Efficiency and noise in operation
Rated efficiency is 94 % at full load — typical for a single-stage planetary with straight teeth, meaning about 6 % of input power is lost as heat in the gear mesh. Noise level measures 58 dB at 1 m under no-load conditions, which is quiet enough for operator-adjacent machinery without additional acoustic enclosures. The black anodized aluminium housing and C45 steel shaft are standard industrial materials — the aluminium body sheds heat well but is softer than cast iron for flange bolt torque.
