Planetary gearbox, 60:1 reduction, 110 N.m continuous
The GBX0800601001F is a straight-tooth planetary gearbox from Schneider Electric's GBX series, with an 80 mm housing diameter and a 60:1 reduction ratio. Continuous output torque is 110 N.m at 100 rpm and 30 °C, with a maximum intermittent torque of 176 N.m under the same conditions — the margin covers acceleration peaks and short overloads in cyclic duty. Rated service life is 30,000 hours at 100 rpm and 30 °C; the gearbox is lubricated for life, so no field maintenance on the oil charge.
Mechanical ratings that govern the fit
Maximum torsional backlash is 16 arc.min — this is the lost motion under reversing loads; for positioning applications requiring tighter repeatability, a lower-backlash gearbox would be needed. Torsional rigidity is 6.3 N.m/arcmin, which defines the wind-up under load — useful for calculating the effective stiffness in the drivetrain. Shaft output is rated IP54, so it handles dust and splashing water but is not suited for washdown or submerged service. Ambient operating range is -25 to 90 °C, covering most indoor industrial environments without derating.
Efficiency and noise — what the numbers mean on the line
Listed efficiency is 94 % — about 6 % of input power is lost as heat in the gear mesh and bearings. For a 110 N.m output at 100 rpm (roughly 1.15 kW mechanical), expect around 70 W of thermal dissipation from the gearbox housing. Noise level is 60 dB at 1 m, no-load — roughly the sound of a quiet office. Under load the noise will rise, but the straight-tooth design is inherently noisier than helical; plan for acoustic enclosures if the application is noise-sensitive.
