It is designed to bolt onto the mating motor in any mounting position and is factory-lubricated for life, so no service access to the gear stage is required in the field. ## Torque envelope and service life Continuous output torque is rated 260 N.m, with a maximum permissible output torque of 416 N.m — so the 260 N.m figure is the steady-state working envelope, while 416 N.m is the short-duration ceiling the gearbox can transmit without immediate fatigue damage. Service life is rated 30,000 h at 100 rpm and 30 °C, and the lubricant is sealed for the life of the unit; sizing decisions are normally made against the duty-cycle curve in the product drawing, not the headline max torque. ## Torsional rigidity and positioning accuracy Torsional rigidity is 13 N.m/arcmin and maximum torsional backlash is 12 arc.min — these two together set how much windup the reducer adds to the drive train, and they are the numbers that decide fit for indexing or servo-positioned applications. Moment of inertia at the input is 1.75 g.cm², which is small relative to the torque output — useful when the gearbox sits ahead of a servo motor where reflected inertia matters for the loop tuning. ## Shaft loading budget Maximum radial load Fr at the output shaft is 1500 N over 30,000 h at 100 rpm / 30 °C, rising to 2000 N if the service life is held to 10,000 h; maximum axial load Fa is 2100 N over 30,000 h or 2800 N over 10,000 h — so a heavier-belted or chain-coupled application shortens the rated life. ## Efficiency, noise and thermal envelope Mechanical efficiency is 94 % and noise level is 65 dB at 1 m under no-load conditions — the efficiency figure drives motor-side sizing (less waste heat to dissipate in the panel) and the noise number indicates a unit suitable for cabinet-integrated machines rather than benchtop or laboratory service. Operating ambient is -25 to 90 °C, so the gearbox can be deployed outside an air-conditioned enclosure provided the surrounding air stays within that band. ## Shaft seal and protection The shaft output side carries IP54 protection — meaning dust-protected and splash-resistant, but not sealed against water jets — so the unit fits dry industrial duty but not washdown environments.","metaTitle":"Schneider Electric GBX1200161081D planetary gearbox, 16:1","metaDescription":"Schneider Electric GBX1200161081D planetary gearbox, 120 mm, 16:1 reduction, 260 N.m continuous, 94 % efficient.
