The GBX1200200702F: This gearbox is classified as Obsolete by Schneider Electric. No official successor is listed. Sourcing is through independent distribution — quantities are confirmed at RFQ against the BOM line.
Torque and duty ratings
Rated for 260 N.m continuous output torque at 100 rpm and 30 °C ambient, with a maximum output torque of 416 N.m under the same conditions. The 20:1 reduction ratio steps the motor speed down while multiplying torque — a 10 N.m input yields 200 N.m at the output, minus the 6 % loss from the 94 % efficiency. Service life is specified at 30,000 hours at 100 rpm and 30 °C. The unit is lubricated for life, so no maintenance schedule for oil changes — just a straight bolt-on and run.
Mechanical limits and integration
Maximum axial force on the output shaft is 2100 N (30,000-hour life) or 2800 N (10,000-hour life) at 100 rpm. Radial force limit is 1500 N for the longer life, 2000 N for the shorter. Both are measured with force applied at mid-distance from the output shaft — overhung loads need to stay within these envelopes to avoid bearing fatigue. The 120 mm diameter black anodized aluminium housing carries a shaft output IP54 rating — suitable for dry indoor environments but not washdown. The C45 steel shaft handles standard keyed couplings. Torsional rigidity is 13 N.m/arcmin, and maximum backlash is 12 arc.min, placing this in the precision class for indexing or positioning applications.
