The 4:1 reduction ratio means the input speed is four times the output speed; torque multiplication follows the inverse ratio minus the 96 % efficiency loss. Service life is 30000 hours at 100 rpm output speed and 30 °C ambient — derate the life figure if the load or temperature exceeds these conditions. ## Backlash and stiffness for positioning Maximum torsional backlash is 12 arcmin at the output — this is the lost motion in the gear train under load reversal, relevant for positioning accuracy in servo or stepper axes. Torsional rigidity is 6 N.m/arcmin — a measure of how much the gearbox wind-up under load; higher stiffness means less deflection for a given torque. Moment of inertia reflected to the input is 0.52 g.cm² — this is the rotational inertia the motor sees, used to calculate acceleration torque requirements. ## Bearing load limits and mounting Maximum axial force (Fa) is 1200 N at 100 rpm for 10000-hour life, derated to 900 N for 30000-hour life at 30 °C — thrust loads from helical or belt drives must stay within these limits. Maximum radial force (Fr) is 950 N at 100 rpm for 10000-hour life, derated to 650 N for 30000-hour life — applies at mid-span of the output shaft. Mountable in any position — no oil fill level constraints, since the gearbox is lubricated for life with no maintenance interval. ## Environmental and mechanical specs Shaft output seal rated IP54 — splash-proof at the rotary seal, but not submersible; the housing is black anodized aluminium, the shaft is C45 steel. Noise level is 60 dB at 1 m, no-load — expect an increase under load; the straight-tooth design is inherently noisier than helical gearing at higher speeds.","metaTitle":"Schneider Electric GBX0800040843D Planetary Gearbox, 4:1","metaDescription":"Schneider Electric GBX0800040843D planetary gearbox, 4:1 reduction, 115 N.m continuous torque, 96% efficiency.
