Continuous output torque is 210 N.m at 100 rpm and 30 °C, with a maximum peak of 336 N.m under the same conditions. Torsional backlash is held to 12 arc.min maximum, and torsional rigidity is rated at 13 N.m/arcmin — figures that matter for positioning accuracy in indexing or pick-and-place applications where lost motion eats into repeatability. ## Shaft loading and service life at rated speed Rated service life is 30,000 hours at 100 rpm and 30 °C. The gearbox ships lubricated for life — no oil-change interval to schedule, which simplifies maintenance on a conveyor or rotary table drive that runs continuously. Maximum radial force at the output shaft is 1500 N (30,000-hour life) or 2000 N (10,000-hour life), measured at mid-span on the shaft. Maximum axial thrust is 2100 N for the longer life target, 2800 N for the shorter. Both figures apply at 100 rpm and 30 °C — derate for higher speed or temperature. The shaft output seal carries an IP54 rating, meaning it resists dust ingress and splashing water — adequate for a dry indoor machine environment but not washdown service. ## Efficiency, noise, and ambient limits Efficiency is listed at 94 %, which means about 6 % of the input power dissipates as heat inside the housing. For a 210 N.m output at 100 rpm (roughly 2.2 kW mechanical), that is about 130 W of heat the anodized aluminium body must shed — factor that into the enclosure ventilation if the gearbox is boxed in. Noise level is 65 dB at 1 m, no-load — roughly the hum of a quiet office printer. Under load the acoustic profile shifts with tooth contact frequency, but the straight-tooth design is inherently noisier than helical at the same torque density. Ambient operating range is -25 to 90 °C, which covers most indoor industrial environments. The C45 steel shaft and black anodized aluminium housing are standard for this class — nothing exotic, but proven in service. Schneider Electric lists the GBX1200090551F as obsolete.
