Torque capacity and duty cycle boundaries
The GBX1600251103G: Continuous output torque is 700 N.m at 100 rpm at 30 °C, with a maximum intermittent rating of 1120 N.m under the same shaft speed and ambient conditions. The 1120 N.m figure is the peak the gearbox can sustain before the service life drops below the 30000-hour baseline. The 25:1 reduction ratio transforms input speed and torque — at 100 rpm output, the input runs at 2500 rpm. The 94 % efficiency means about 6 % of the input power is lost as heat, which the black anodized aluminium housing dissipates across the -25 to 90 °C operating range.
Sourcing reality — obsolete, sourced per RFQ
Schneider Electric lists this planetary gearbox as obsolete. Sourcing runs through independent distribution channels — quantities are lot-specific and confirmed at quote time against your BOM line. The gearbox carries no published compliance documentation beyond what the manufacturer originally supplied. No RoHS, REACH, UL, or IEC certificates appear in the current record — verify documentation requirements with your quality team before committing to a production line.
Mechanical constraints for integration
Gearbox external diameter is 160 mm, shaft material is C 45 steel. The shaft output seal carries IP54 protection — adequate for dry indoor environments but not washdown. Housing colour is black, mounting position is any orientation, and the unit ships lubricated for life with no maintenance interval. Maximum axial force on the output shaft is 6000 N at 100 rpm for the 30000-hour service life, or 8000 N if you accept a reduced 10000-hour life. Radial force limits are 4200 N (30000-hour) and 6000 N (10000-hour), measured at mid-distance from the shaft end.
