The GBX code is the device short name and compatibility key on the mating servo or brushless side, so the gearbox drops onto the standard GBX input stage without an adapter plate. Class is Gear Reducers & Gearboxes (cites:); a planetary unit of this size is the typical torque amplifier between a servo or stepper drive and a high-inertia load — conveyors, packaging indexing tables, rotary knife stations, and rotary unions on a filling line are the deployment context implied by the 120 mm frame. ## Torque envelope and efficiency Continuous output torque is 230 N.m and maximum output torque is 368 N.m, so the unit absorbs cyclic overloads without slipping past the rated envelope (cites:,). The 15:1 reduction multiplies motor torque by that ratio before subtracting the 94 % efficiency figure, which is the conduction loss floor at the gear mesh and bearing drag combined. Moment of inertia is 2.53 g.cm² at the input — low enough that a mid-size servo accelerates the gearbox without a separate inertia-matching calc (cites:). Torsional rigidity is 13 N.m/arcmin and maximum torsional backlash is 12 arc.min, which is the precision class that the < 12 arc.min marketing line on the description pulls from (cites:,). ## Shaft loads and the precision-vs-life trade Maximum radial force Fr is 1500 N at 100 rpm for the 30000 h service-life profile and 2000 N at 100 rpm for the 10000 h profile, applied at mid-distance from the output shaft; maximum axial force Fa is 2100 N at 100 rpm over 30000 h and 2800 N at 100 rpm over 10000 h (cites:,). The two ratings are the same shaft with two different duty assumptions — the higher force number is the short-life duty, the lower force number is the full-life duty, and the buyer chooses which curve governs based on how many hours the line actually runs. IP54 on the shaft output keeps dust and light splashing out of the seal area; it is not a washdown rating, so food-and-bev lines with high-pressure cleaning should look elsewhere or fit a bellows cover (cites:). Noise level is 65 dB at 1 m no-load, which is the quiet end of the straight-tooth class — helical gears would drop that further but at a price premium. ## Operating envelope and service life Service life is rated 30000 h at 100 rpm and 30 °C ambient, with the unit lubricated for life so there is no relube interval on the maintenance schedule (cites:,). Ambient temperature for operation is -25...90 °C, and mounting position is any position — the grease fill and seal orientation are designed for the shaft pointing in any direction without remounting the breather.","metaTitle":"GBX1200150842D Schneider Planetary Gearbox, 15:1, 230 N.m","metaDescription":"Schneider Electric GBX1200150842D planetary gearbox, 120 mm frame, 15:1 reduction, 230 N.m continuous output.
