The format is the standard for pairing a servo or stepper drive to a slower, higher-torque output shaft where stiffness and repeatable positioning matter. ## Torque envelope and service life Continuous output torque is rated at 700 N.m and maximum output torque at 1120 N.m, with a 30000 h service life at 100 rpm and 30 °C. At higher speeds or elevated ambient the life figure drops — the 30000 h rating is the reference condition, not a guarantee in every installation. Torsional rigidity sits at 41 N.m/arcmin, which is what keeps torsional wind-up tight under shock loads and what makes a 40:1 planetary appropriate where the motor side is being commanded as a positioning axis rather than a free-running speed reducer. ## Thrust loads and mounting envelope Maximum radial force Fr is 4200 N at 100 rpm for the full 30000 h life, rising to 6000 N if the duty is held to 10000 h; maximum axial force Fa mirrors that curve at 6000 N (30000 h) and 8000 N (10000 h), both with the force applied at mid-distance from the output shaft at 30 °C. Belt or pinion overhung loads must be checked against the Fr curve — it is the radial component, not the torque figure, that the bearing stack survives. The unit mounts in any position, runs from -25 °C to 90 °C ambient, and the shaft output is sealed to IP54. The shaft is C45 steel in a black anodized aluminium housing, and the gearbox is lubricated for life — no grease points on the installation drawing. Efficiency is 94 % and the no-load noise figure is 70 dB at 1 m, both consistent with a precision planetary stage. The moment of inertia at the input is 5.28 g.cm², small enough not to dominate sizing on most servo pairings. ## Lifecycle status — obsolete, quoted against the BOM Buyers covering this gearbox against a critical spare or a panel build should treat each unit as a finite lot: confirm quantity, traceability, and the production date code at quote time, and flag the BOM line for a like-for-like replacement review if the design has not yet frozen.","metaTitle":"Schneider GBX1600401385D planetary gearbox, 40:1, 700 N.m","metaDescription":"Schneider Electric GBX1600401385D, 160 mm planetary gearbox, 40:1 ratio, 700 N.m continuous / 1120 N.m peak.
