What the GBX1200201081D is sized to do
The GBX1200201081D is a planetary gearbox from Schneider Electric's GBX series with a 20:1 reduction ratio, delivering 260 N.m continuous output torque and peaking at 416 N.m maximum — pairing it with a servo or stepper drive sized to the application load gives the working torque headroom without driving the gearbox into its short-duration maximum on every cycle. Efficiency is listed at 94 %, which is the number the system designer multiplies by the motor's mechanical output to get torque at the gearbox shaft before adding the load inertia and the cyclic torque margin. No-load noise is 65 dB at 1 m, which matters on cells where the operator stands close to the reducer during a changeover — quieter gearboxes are not just a comfort issue, they keep the cell below thresholds that trigger hearing-protection zones on the shop floor.
Shaft loads the housing is built to take
The shaft is C 45 carbon steel in a black anodized aluminium housing, rated for 1500 N radial force at 100 rpm over the full 30000-hour service life at 30 °C, rising to 2000 N if the duty is bounded to 10000 hours; the axial envelope is 2100 N continuous or 2800 N over the shorter 10000-hour window, so the design decision is whether the line runs near the higher load with a planned reducer swap or sits comfortably at the lower load for life. Torsional rigidity is 13 N.m/arcmin and maximum torsional backlash is 12 arc.min, which is the figure the motion engineer uses to compute positioning error at the output — the lower the backlash, the tighter the repeatable stop on indexing or pick-and-place axes. Moment of inertia at the input is 1.5 g.cm², small enough that coupling it to a typical servo does not push the drive's inertia ratio past the 10:1 guideline most servo controllers enforce for stable current loop tuning.
Service envelope and where it mounts
Operating temperature spans -25...90 °C and the unit is lubricated for life, so there is no scheduled oil change on the maintenance plan — the service interval is the 30000-hour figure at 100 rpm and 30 °C, which scales with both speed and temperature when the real duty drifts from those test conditions. Mounting position is any orientation, which removes a constraint that frequently disqualifies inline reducers in machine frames where the output shaft needs to point up, down, or at an angle — the 120 mm housing diameter is the only footprint number the panel layout carries. The shaft output carries an IP54 seal rating, meaning it is protected against dust ingress and splashing water but not high-pressure washdown; if the gearbox is going onto a food-and-beverage or outdoor line, the enclosure around the output shaft is what has to carry the rest of the sealing duty.
