Continuous output torque is rated 230 N.m, with a maximum output torque of 368 N.m and a service life of 30000 h at 100 rpm at 30 °C — that thermal envelope is the figure that governs the real duty, not the headline peak number. Torsional rigidity is 13 N.m/arcmin against a maximum torsional backlash of 12 arc.min, so for a 40:1 stage on a positioning axis the resolution loss at the output shaft sits in that arcmin bracket. For belt-and-pulley or coupling-driven loads, the rated radial force of 1500 N at mid-shaft over the 30000 h envelope and axial force of 2100 N over the same envelope are the shaft-load limits the bracket must be sized within — those values rise to 2000 N radial and 2800 N axial on a shorter 10000 h duty. ## Efficiency, noise, and the envelope around the gearbox Mechanical efficiency is 94 %, with a no-load noise level of 65 dB at 1 m — that's the floor on heat dissipation and acoustic signature, both relevant when the gearbox is mounted inside an enclosure next to a servo amplifier. The unit is lubricated for life, so there is no planned re-grease interval in the maintenance schedule. ## Sourcing reality — the line is on this code, not the next one The GBX1200400701D is recorded as obsolete by the manufacturer, with no official successor order code on the lifecycle record.","metaTitle":"GBX1200400701D Schneider GBX Planetary Gearbox, 40:1","metaDescription":"Schneider Electric GBX1200400701D planetary gearbox, 40:1 reduction, 230 N.m continuous / 368 N.m peak, 12 arc.min backlash.
