Maximum radial force Fr follows the same pattern — 200 N at 100 rpm for 10000 hours, 160 N for 30000 hours, with the force applied at mid-distance from the output shaft. The gearbox is lubricated for life, so there is no maintenance schedule for grease changes — one less item on the PM checklist. ## Backlash and torsional stiffness for positioning Maximum torsional backlash is 30 arcmin — this is a standard-precision planetary, not a zero-backlash unit, so it suits indexing and positioning where the load holds position between moves rather than reversing under load. Torsional rigidity is 1 N.m/arcmin — the shaft wind-up under rated torque is predictable, and the C 45 steel shaft material handles the bending moment from radial loads.","metaTitle":"Schneider Electric GBX0400030403D Planetary Gearbox, 3:1","metaDescription":"Active-production planetary gearbox from Schneider Electric. 3:1 reduction, 96% efficiency, 40 mm diameter, 30 arcmin backlash.
