Planetary gearbox for precision motion
The GBX0600150704F is a 60 mm diameter planetary gearbox from Schneider Electric, straight-tooth design, with a 15:1 reduction ratio. It delivers 44 N.m continuous output torque at 100 rpm, with a maximum intermittent torque of 70 N.m. Rated service life is 30,000 hours at 100 rpm and 30 °C ambient — the gearbox is lubricated for life, so no maintenance schedule for oil changes.
Torque, backlash, and stiffness
Continuous torque rating of 44 N.m at 100 rpm defines the steady-state load capacity; the maximum output torque of 70 N.m covers peak or start-up loads. Torsional rigidity is 2.5 N.m/arcmin — a measure of how much the output shaft twists under load, important for positioning accuracy in indexing or pick-and-place. Maximum torsional backlash is 20 arc.min — the lost motion between input and output when reversing direction. For applications requiring repeatable positioning, this figure sets the lower bound on achievable accuracy. Rated axial force (Fa) is 450 N for the 30,000-hour life, and radial force (Fr) is 340 N when applied at mid-span of the output shaft. Exceed these and bearing life shortens.
Efficiency, noise, and environmental limits
Efficiency is listed at 94 % — typical for a single-stage planetary with straight teeth. The 58 dB noise level at 1 m, no-load, is quiet enough for lab or light industrial environments. Housing is black anodised aluminium; shaft material is C45 steel.
