Service life is rated at 30000 hours at that continuous load — if you push it to the maximum torque, expect the life to drop proportionally. The 40:1 reduction ratio and 94% efficiency mean the input motor sees a reflected inertia roughly 1600 times the gearbox's own 0.39 g.cm² — a factor that matters when sizing the brake resistor on a servo axis. ## Shaft loads and mounting constraints Maximum radial force at the output shaft is 650 N for the 30000-hour service life at 100 rpm, applied at mid-distance from the shaft face. Axial force is capped at 900 N for the same service window. These are the limits that govern bearing life — overshoot them and you'll be swapping the gearbox before the lubrication runs dry. The IP54 shaft output seal keeps washdown spray out of the bearings, but the housing itself is black anodized aluminium — fine for dry indoor duty but not rated for submersion. Mounting position is unrestricted, so you can orient it any way that fits the machine frame. ## Backlash and torsional stiffness Maximum torsional backlash is 14 arc.minutes — that's a standard-precision planetary, not a zero-backlash unit. If your positioning loop expects better than 0.23 degrees of lost motion at the output, this gearbox will add that compliance into the servo tuning budget. Torsional rigidity is 6.5 N.m/arcmin, which means the gearbox winds up about 17 arcmin under the 110 N.m continuous torque. That windup is predictable and repeatable, so it can be compensated in the controller if the application demands it.","metaTitle":"Schneider GBX0800400702F Planetary Gearbox, 40:1, 110 N.m","metaDescription":"Schneider Electric GBX0800400702F planetary gearbox, 80 mm diameter, 40:1 ratio, 110 N.m continuous torque, 94% efficiency.
