Planetary gearbox for precision motion control
The Schneider Electric GBX1600401382D is a planetary gearbox in the GBX series, designed to reduce motor speed by a 40:1 ratio while increasing output torque. It delivers a continuous output torque of 700 N.m and can handle peak loads up to 1120 N.m maximum output torque. The straight-tooth gearing keeps torsional backlash within 10 arcmin, which matters for positioning accuracy in indexing or pick-and-place applications where lost motion translates directly to position error.
Rated for sustained duty in a servo train
Efficiency is listed at 94 %, meaning 6 % of the input power is lost as heat in the gear mesh and bearings — a figure that holds up well for a single-stage planetary with straight teeth. The noise level at no-load is 70 dB at 1 m, which is within the typical range for a gearbox of this size and ratio. Service life is specified as 30000 hours at 100 rpm and 30 °C ambient. The gearbox is lubricated for life, so no maintenance interval for oil changes — a practical detail for a sealed unit in a production line. The housing is black anodized aluminium with a 160 mm external diameter. Shaft output sealing is IP54, which is splash-proof but not submersible — suitable for dry indoor environments or enclosures where coolant mist is present.
