Planetary gearbox for precision motion — 80 mm frame, 20:1 reduction
The GBX0800201404F is a straight-tooth planetary gearbox in the 80 mm diameter frame, delivering a 20:1 reduction ratio. It is designed for servo or stepper motor output stages where compact inline mounting and moderate precision are required. Continuous output torque is 120 N.m at 100 rpm, with a maximum intermittent torque of 192 N.m at the same speed. The 14 arc.min torsional backlash places it in the standard-precision class — adequate for positioning conveyors, indexing tables, and pick-and-place axes that do not require zero-backlash performance. Rated service life is 30,000 hours at 100 rpm and 30 °C ambient, with the gearbox lubricated for life — no oil changes or regreasing intervals over the service window. The shaft output seal is rated IP54, protecting the bearings and gears from dust and splash in dry indoor environments.
Rated loads and thermal limits — axial and radial force capacity
Maximum axial force (Fa) on the output shaft is 1200 N at 100 rpm for a 10,000-hour life, derated to 900 N for the full 30,000-hour service life. Radial force (Fr) applied at mid-shaft is 950 N for 10,000 hours or 650 N for 30,000 hours at 100 rpm. The housing is black anodized aluminium, and the output shaft is C45 steel. Ambient temperature range for operation is -25 °C to 90 °C, with no derating required within that band for the torque ratings listed. Efficiency is 94 % at rated load, and noise level is 60 dB at 1 m under no-load conditions — quiet enough for laboratory or assembly-line environments without additional acoustic enclosures.
Obsolete — sourcing through independent channels
Schneider Electric has marked the GBX0800201404F as obsolete. This gearbox is available through independent surplus and broker channels.
