This is sized for servo motor output where you need high torque multiplication in a compact, low-backlash package. Continuous output torque is rated 120 N.m at 100 rpm and 30 °C ambient, with a maximum intermittent torque of 192 N.m under the same conditions. ## Backlash, stiffness, and load limits that decide fit Maximum torsional backlash is 16 arcmin — this is a standard-precision planetary, not a zero-backlash unit. If your application is a pick-and-place or rotary table with reversal accuracy under 5 arcmin, this gearbox introduces enough lost motion to need compensation in the servo tuning or a higher-grade planetary. Torsional rigidity is 6.3 N.m/arcmin — the gear train twists under load, and this number lets you calculate the windup at the continuous torque: 120 N.m / 6.3 ≈ 19 arcmin deflection before you even hit the backlash. Combined with the 16 arcmin backlash, the total angular error at full continuous torque is around 35 arcmin. Maximum radial force Fr is 650 N applied at mid-span on the output shaft at 100 rpm for the 30,000-hour service life; axial force Fa is 900 N for the same life. Short-term (10,000-hour) ratings are higher: 950 N radial and 1200 N axial. These limits are the binding constraint for belt-pulley or direct-coupling loads — overshoot them and the output bearing life drops below the gearbox service life. ## Lifecycle status — obsolete, sourced through surplus channels Schneider Electric lists the GBX0800801003F as obsolete. This gearbox is available through independent surplus and broker inventory — each lot is sourced and quoted against a specific RFQ, with quantity and condition confirmed at quote time. Service life is rated 30,000 hours at 100 rpm and 30 °C ambient, with the gearbox lubricated for life — no re-greasing interval. After the service life expires, the gear mesh wear increases backlash and noise beyond the original 60 dB no-load spec. For a line-down replacement, confirm the remaining life budget matches your production window. ## Construction and sealing for the mounting environment Housing is black anodized aluminium, 80 mm outer diameter. The shaft is C45 carbon steel. IP54 at the shaft output — this seals against dust ingress and splashing water, but not against pressurized washdown. The IP54 rating means the gearbox is suited for dry indoor environments or areas with occasional mist; for food-processing or outdoor washdown, a sealed motor adapter or cover is needed. Noise level is 60 dB at 1 m, no-load — this is typical for a straight-tooth planetary at 100 rpm input. Under load, expect an increase of 3-6 dB depending on torque and alignment.","metaTitle":"Schneider GBX0800801003F Planetary Gearbox, 80:1, 120 N.m","metaDescription":"Schneider Electric GBX0800801003F planetary gearbox, 80:1 ratio, 120 N.m continuous torque, 94% efficiency.
