The 3:1 reduction ratio transforms input speed to output torque at 96 % efficiency, meaning 4 % of the input power is lost as heat in the gear mesh — a relevant figure for the thermal budget in a sealed enclosure. ## Mechanical interface and overhung load limits The 80 mm diameter black anodised aluminium housing with C 45 steel shaft accepts a maximum radial force of 650 N at 100 rpm (mid-shaft, 30000-hour life) and a maximum axial force of 1200 N at 100 rpm (10000-hour life) — these limits must be respected when mounting a pinion or pulley directly on the output shaft to avoid bearing overload. Torsional rigidity is 6 N.m/arcmin, and maximum torsional backlash is 12 arc.min — the backlash figure sets the positioning repeatability floor for a reversing load; a servo tune with anti-backlash compensation may be required if the application cycles through zero torque. ## Environmental and integration constraints The shaft output carries IP54 protection — the gearbox is splash-resistant but not sealed against pressurised washdown; the housing itself is not separately IP-rated, so the IP54 applies only at the shaft seal interface. Noise level is 60 dB at 1 m, no-load — this is the acoustic baseline with straight-cut teeth; under load the noise floor will rise with transmitted torque and speed.","metaTitle":"Schneider Electric GBX0800030703D Planetary Gearbox, 3:1","metaDescription":"Schneider Electric GBX0800030703D planetary gearbox, 80 mm, 3:1 ratio, 85 N.m continuous torque, 96 % efficiency.
