Planetary gearbox for precision motion — 80 mm frame, 4:1 reduction
The GBX0800040551F is a Schneider Electric planetary gearbox with straight teeth, 80 mm outer diameter, and a 4:1 reduction ratio. It delivers a continuous output torque of 115 N.m (1017.8 lbf.in) at 100 rpm and 30 °C. Rated efficiency is 94 %, with a noise level of 60 dB at 1 m under no-load conditions — useful for noise-sensitive production environments.
Torque, backlash, and load ratings that govern the fit
Maximum output torque reaches 184 N.m (1628.5 lbf.in) at 100 rpm and 30 °C, but the continuous rating of 115 N.m is the design-in figure for sustained duty. Torsional rigidity is 6 N.m/arcmin, and maximum torsional backlash is 9 arcmin — this sets the positioning repeatability floor for indexing or pick-and-place axes. Service life is 30,000 hours at 100 rpm and 30 °C. The gearbox is lubricated for life, so no maintenance oil changes are needed over that span. Maximum axial force (Fa) is 1200 N at 100 rpm for 10,000 hours, derating to 900 N for the full 30,000-hour life. Maximum radial force (Fr) at mid-shaft is 950 N for 10,000 hours or 650 N for 30,000 hours — these limits govern bearing selection in the driven load. Shaft output sealing is IP54, and the housing is black anodized aluminium with a C45 steel shaft. Ambient operating range spans -25 to 90 °C.
