Its 25:1 reduction ratio and 230 N.m continuous output torque make it a fit where moderate-inertia servo motors are paired with the gearbox downstream of the coupling — the spec sheet reads like a mid-range precision reducer rather than a high-ratio or right-angle unit (cite:)(cite:). ## Torque envelope, backlash and the ratings that decide a swap Continuous output torque is rated 230 N.m, with a maximum output torque of 368 N.m for transient peaks — the peak number is the figure to check against the application's acceleration demand, not the steady-state value (cite:)(cite:). Maximum torsional backlash is 12 arc.min and torsional rigidity 13 N.m/arcmin, with a moment of inertia of 1.49 g.cm² — a backlash figure in the low-teens arc-minutes places the unit in the general-purpose precision band, well below true low-backlash planetary gearheads but tighter than a worm or helical unit (cite:)(cite:)(cite:). Service life is rated 30000 h at 100 rpm and 30 °C, lubricated for life — meaning the unit is sealed and not field-serviceable for grease replenishment, so the duty-cycle assumption matters more than the headline torque (cite:)(cite:). Maximum radial load Fr is 1500 N at 100 rpm over the 30000 h service envelope (2000 N over a shorter 10000 h life), and maximum axial load Fa is 2100 N over the same envelope — both figures are stated with the load applied at mid-distance from the output shaft, so a heavy pulley or pinion mounted at the shaft end derates sharply against these numbers (cite:)(cite:). Efficiency is 94 %, so losses are real but small — at the 230 N.m continuous rating the gearbox drops roughly 14 N.m to heat, which feeds into the housing-temperature rise the bearings must reject (cite:). ## Mechanical envelope and the environment it survives IP54 at the shaft output and an operating temperature range of −25...90 °C mean the gearbox tolerates washdown-light or sheltered outdoor panels, but the IP54 rating at the seal excludes the high-pressure hose-down zones that an IP65 or IP67 reducer would survive (cite:)(cite:). Mounting position is any orientation and noise is rated 65 dB at 1 m on no-load — the any-position rating means the gearbox does not require a specific oil-level orientation, which matters when retrofitting into a machine where the drive orientation is fixed (cite:)(cite:). ## Lifecycle reality — obsolete, sourced on the independent channel For a packaging line with this reducer fitted, that means spares are now a procurement problem rather than a stock problem: the unit must be sourced as a known part number against an RFQ, with availability and unit pricing confirmed at quote time, not pulled from a current catalogue (cite:)(cite:). Compatibility code GBX means the unit mates with the GBX-family servo-adapter plates and the matching input module for the motor it was specified against — a replacement from a different gearbox family will require checking the input coupling, pilot and bolt pattern before it can drop in (cite:)(cite:).","metaTitle":"Schneider Electric GBX1200250841D Planetary Gearbox, 25:1","metaDescription":"Schneider Electric GBX1200250841D planetary gearbox, 25:1 reduction, 230 N.m continuous / 368 N.m peak, Ø120 mm.
