Planetary gearbox with 9:1 reduction — 130 N.m continuous, 208 N.m peak
The GBX0800091403F is a straight-tooth planetary gearbox from Schneider Electric's GBX series, 80 mm housing diameter, with a 9:1 reduction ratio. It delivers 130 N.m continuous output torque at 100 rpm and 30 °C, and a maximum output torque of 208 N.m under the same conditions. Rated efficiency is 94 %, and the no-load noise level is 60 dB at 1 m — both figures that matter when the gearbox is integrated into a precision motion axis where thermal and acoustic budgets are tight.
Torque, backlash, and service life — the numbers that decide the fit
Continuous torque is 130 N.m; the peak allowable is 208 N.m, but only at 100 rpm and 30 °C. The torsional rigidity is 6.5 N.m/arcmin, and maximum torsional backlash is 14 arc.min — a spec that governs positioning repeatability in indexing or pick-and-place applications. Service life is rated 30,000 hours at 100 rpm and 30 °C. The gearbox is lubricated for life, so no maintenance oil changes — a factor for installations where access is difficult. Maximum axial force (Fa) is 1200 N for a 10,000-hour life at 30 °C, or 900 N for 30,000 hours. Maximum radial force (Fr) at mid-span on the output shaft is 950 N for 10,000 hours, 650 N for 30,000 hours. The shaft output seal is rated IP54, enough for dry indoor environments but not washdown.
Obsolete — sourcing through independent channels
Schneider Electric lists the GBX0800091403F as obsolete. No official successor is recorded. For a critical spare on legacy equipment, the only channel is independent surplus or broker stock — quantities are lot-specific and confirmed at RFQ. If you are holding a machine that uses this gearbox, the 30,000-hour service life means a replacement may already be due. Sourcing a spare before the line goes down is the prudent move — one in the cabinet beats a frantic search later.
