3:1 planetary — 28 N.m continuous, 45 N.m peak
The GBX0600031403F: This is a Schneider Electric GBX-series planetary gearbox, 60 mm diameter, with a 3:1 reduction ratio. It delivers 28 N.m continuous output torque at 100 rpm and 30 °C, and can handle 45 N.m maximum for short-duration peaks. The straight-tooth design keeps backlash at 16 arc.min — fine for positioning axes where a few arc-minutes of lost motion is acceptable, but not for zero-backlash servo applications. Rated service life is 30,000 hours at 100 rpm and 30 °C, and it ships lubricated for life — no maintenance schedule for oil changes.
Load ratings and environmental limits
Maximum axial force on the output shaft is 450 N, and maximum radial force is 340 N — both at 100 rpm, mid-shaft, for the full 30,000-hour life. For shorter duty (10,000 hours), radial force can go to 500 N. Torsional rigidity is 2.3 N.m/arcmin — the shaft twists about 0.43 arcmin per N.m of load torque. Efficiency is 94 % at rated load, and noise measures 58 dB at 1 m, no-load — quiet enough for a lab bench or light production line.
Obsolete — sourced through surplus channels
Schneider Electric lists this gearbox as obsolete. Available through independent surplus distribution — quantities are lot-specific, and condition (new-in-box, sealed) is confirmed at RFQ. No pin-compatible direct replacement exists from Schneider; a functional substitute would require checking the mounting footprint and shaft dimensions.
