That ratio multiplies motor torque by 40 while dividing output speed by the same factor — a common match for servo motors in indexing, positioning, or conveyor drives where the motor runs at efficient speed and the gearbox delivers the torque at the load. Continuous output torque is 110 N.m at 100 rpm (30 °C ambient), with a maximum intermittent torque of 176 N.m at the same speed. The 110 N.m figure is the thermal limit — the gearbox can run at that load indefinitely without exceeding the rated service life of 30,000 hours. The 176 N.m peak covers acceleration and emergency stops, but sustained operation above 110 N.m will shorten the life below the 30,000-hour target. Backlash is 14 arcmin maximum — that's the angular play between input and output when reversing direction. For pick-and-place or positioning axes where reversal accuracy matters, 14 arcmin is a standard commercial-grade figure; if the application needs tighter positioning, a lower-backlash variant from the same family would be the pick. ## Mechanical limits and integration — shaft loads, mounting, and environment The output shaft accepts a maximum radial force of 650 N (force applied at mid-shaft distance) for the 30,000-hour life target, and 950 N for a 10,000-hour duty cycle. Maximum axial force is 1200 N for 10,000 hours, dropping to 900 N for the full 30,000-hour service life. These limits are at 100 rpm and 30 °C — overspeed or higher temperature derates both figures. Shaft material is C45 steel (medium-carbon, good wear resistance), housing is black anodized aluminium. The shaft output seal carries IP54 protection — splash-resistant but not washdown-rated. Mounting position is any orientation, which simplifies integration into tight machine frames. Torsional rigidity is 6.5 N.m/arcmin — this tells you how much the gearbox twists under load. At 110 N.m continuous torque, the windup is roughly 17 arcmin (110 ÷ 6.5). For servo loops with high-gain tuning, that windup adds to the total compliance in the axis and may need compensation in the drive's stiffness settings. The gearbox is lubricated for life — no maintenance oil changes. Operating ambient range is -25 °C to 90 °C, which covers most indoor industrial environments including unheated warehouses. Efficiency is 94 %, meaning 6 % of input power is lost as heat through the gear mesh and bearings.","metaTitle":"Schneider Electric GBX0800400703F planetary gearbox, 40:1","metaDescription":"Schneider Electric GBX0800400703F planetary gearbox, 80 mm frame, 40:1 ratio, 110 N.m continuous torque, 94% efficiency.
