Schneider marks the product obsolete on the lifecycle record, so the practical question for a buyer sourcing it today is not whether it still fits the BOM but how much of the original lot is recoverable through independent channels. ## Torque envelope and life-rated load limits Maximum output torque is 368 N.m against a continuous rating of 230 N.m, and torsional rigidity is 13 N.m/arcmin with a maximum torsional backlash of 12 arc.min — numbers that determine whether the gearbox will hold positioning accuracy on a servo-driven axis without coasting into the load. Service life is 30000 h at 100 rpm at 30 °C, with the maximum radial force Fr listed at 1500 N and maximum axial force Fa at 2100 N over that same 30000 h envelope; at 10000 h the limits rise to 2000 N radial and 2800 N axial. ## Mechanical and environmental envelope The shaft is C 45 steel in a black anodized aluminium housing, with IP54 protection at the shaft output — enough for an indoor cabinet-mounted axis but not a washdown or outdoor installation. Operating ambient is -25...90 °C, which covers most factory floors but rules out sub-freezing or high-heat cells without re-derating. Mounting position is unrestricted, so the reducer drops into horizontal, vertical, or inclined brackets without a special order variant. ## Efficiency, noise, and dynamic behaviour Efficiency is 94 % and noise level is 65 dB at 1 m no-load — quiet enough for an operator-attended cell, and efficient enough that the gearbox does not dominate the drive's thermal budget. Moment of inertia is 1.49 g.cm², low for the 120 mm frame and useful on start-stop or reversing axes where reflected inertia at the motor limits acceleration.","metaTitle":"Schneider GBX1200250702D Planetary Gearbox, 25:1, 230 N.m","metaDescription":"Schneider Electric GBX1200250702D — obsolete planetary gearbox, 25:1 reduction, 230 N.m continuous torque.
