Obsolete — what that means for procurement
Schneider Electric lists the GBX1200401004F as obsolete. This planetary gearbox is sourced through independent surplus and broker channels.
Torque and duty ratings that matter
Continuous output torque is 230 N.m at 100 rpm and 30 °C ambient — this is the sustained load the gearbox can carry through its 30,000-hour service life. Maximum output torque reaches 368 N.m at the same speed and temperature, but that is the peak overload figure, not the continuous rating.
Reduction, backlash, and efficiency
Reduction ratio is 40:1 with a maximum torsional backlash of 12 arc.min — straight-tooth planetary design, so some backlash is inherent; this is not a zero-backlash stage. Efficiency is listed at 94 %, which is typical for a single-stage planetary with straight teeth at this ratio.
Mechanical limits and integration
Maximum axial force Fa is 2100 N for the 30,000-hour life target, or 2800 N if the application accepts a shorter 10,000-hour service window. Maximum radial force Fr is 1500 N for 30,000 hours, or 2000 N for 10,000 hours, with the force applied at mid-distance from the output shaft. Shaft output carries an IP54 rating — protected against dust ingress and splashing water, but not submersion or high-pressure washdown. Housing is black anodized aluminium, shaft material is C45 steel. The gearbox is lubricated for life and requires no maintenance between rebuild intervals.
