Torque ratings that define the load envelope
The GBX1600200704F delivers a continuous output torque of 800 N.m at 100 rpm, with a maximum intermittent torque of 1280 N.m at the same speed. The 20:1 reduction ratio means the input runs 20 times faster than the output — a 1500 rpm motor yields 75 rpm on the output shaft, scaled by the ratio squared for inertia matching. Service life is rated 30,000 hours at rated load; the gearbox is lubricated for life, so no oil-change interval to schedule. The 94 % efficiency keeps thermal rise low in continuous duty, but the real limit is the output bearing capacity — axial force max 6000 N and radial force max 4200 N at mid-shaft, both at 100 rpm over the 30,000-hour life.
Backlash and stiffness for positioning accuracy
Maximum torsional backlash is 10 arc.min — standard precision for a straight-tooth planetary. Torsional rigidity is 41 N.m/arcmin, so a 410 N.m load twist the output by about 10 arcmin. For indexing or pick-and-place applications, this backlash must be accounted for in the position loop; a lower-backlash gearbox (e.g., 3 arcmin) would be needed for servo-grade accuracy. The 160 mm diameter housing is black anodized aluminium, shaft material C45 steel. Shaft output is IP54 — protected against dust ingress and splashing water, but not washdown. Mounting envelope: the gearbox external diameter is 160 mm; plan for the output shaft keyway and the input flange pattern from the motor supplier.
Obsolete — sourcing through independent channels
Schneider Electric lists the GBX1600200704F as obsolete. The part is available through independent surplus and broker channels — quantities are lot-specific and confirmed at RFQ. For a critical spare holding on legacy equipment, this is the kind of part you buy one of before it fails; no spare, no sleep.
