Continuous output torque is 700 N.m and maximum output torque reaches 1120 N.m, so the unit is built for sustained mid-range drive work rather than peak shock loads — sizing should be done against the continuous figure with the maximum reserved for transient acceleration. Efficiency is 94 %, which is typical for a precision planetary stage at 40:1 and means roughly 6 % of the input power is converted to heat inside the housing — worth budgeting into the enclosure thermal calculation when the gearbox runs at rated torque for long duty cycles. ## Backlash, rigidity, and what 10 arc.min buys the integrator Maximum torsional backlash is 10 arc.min with a torsional rigidity of 41 N.m/arcmin, a stiffness figure that lets the gearbox hold position under reversing load without the wind-up that wrecks repeatability on indexing axes. Moment of inertia at the input is 5.28 g.cm² — a low figure that keeps the gearbox from dominating the acceleration budget when paired with a mid-size servo, which matters on high-cycle pick-and-place or packaging axes where every g.cm² above the motor rotor costs cycle time. Service life is rated 30000 h at 100 rpm at 30 °C, so continuous-duty sizing should keep the average output speed near that benchmark; running well above 100 rpm shortens bearing life and pushes the lubricant beyond its design envelope. ## Shaft loads and the IP54 seal at the output Maximum radial force Fr at mid-distance from the output shaft is 4200 N over the full 30000 h life at 100 rpm, rising to 6000 N if the duty is capped at 10000 h at 100 rpm — the higher figure is the short-life rating, and a belt or pinion mounted outboard should be dimensioned to stay under the long-life number to keep the L10 bearing assumption honest. Maximum axial force Fa follows the same time derate: 6000 N at 100 rpm over 30000 h, 8000 N at 100 rpm over 10000 h at 30 °C, so a vertically hung screw or a thrust-bearing-mounted pulley needs to land inside the long-life figure unless the buyer is accepting a shortened service interval. The shaft output carries an IP54 seal, which excludes dust ingress and resists splashing water from any direction — adequate for an enclosure-mounted or covered-machine application, but not for a washdown cell where IP65 or higher would be the floor. ## Operating envelope and mounting posture Ambient operating temperature is -25 to 90 °C, wide enough for most factory and outdoor cabinet installations; the upper end sits above typical servo-amplifier ratings, so the gearbox will not be the first component to derate in a hot enclosure. The unit is lubricated for life — no service port or oil-change interval, which removes a maintenance line item but means the 30000 h figure is the hard replacement trigger. Mounting position is rated for any orientation, so the gearbox can be hung from a ceiling frame, stood on a baseplate, or tilted to a machine bed without derating the bearing or lubrication assumptions. Noise level is 70 dB at 1 m under no-load, the figure a safety officer uses to decide whether the gearbox needs a sound enclosure when it sits inside a workstation rather than inside a panel.","metaTitle":"Schneider Electric GBX1600400842D Planetary Gearbox, 40:1","metaDescription":"Schneider Electric GBX1600400842D planetary gearbox, 40:1 reduction, 700 N.m continuous output, 160 mm frame.
