It delivers 700 N.m continuous output torque at 100 rpm and 30 °C ambient, with a peak of 1120 N.m under the same conditions. The 94 % efficiency means about 6 % of input power is lost as heat through the straight-tooth mesh — acceptable for most servo and positioning axes, but the thermal rise at sustained full load needs to be accounted for in the enclosure size. Maximum torsional backlash is 10 arc.min — this is a standard-precision planetary, not a zero-backlash stage. For indexing or pick-and-place with tight positional repeatability, budget the backlash into the servo loop or look at a preloaded unit. ## Force limits and service life — the real constraints Rated service life is 30,000 hours at 100 rpm and 30 °C, lubricated for life — no oil changes, but the grease fill sets the thermal ceiling. Exceeding the 30 °C ambient or running sustained above 100 rpm shortens the life proportionally. Maximum axial force on the output shaft is 6000 N for the full 30,000-hour life, or 8000 N if you accept a 10,000-hour service interval. Radial force limits are 4200 N and 6000 N respectively, measured at mid-span on the shaft. The shaft output seal is rated IP54 — splash-proof but not washdown. In dusty or wet environments, the motor-side seal and the gearbox breather (if any) need separate protection. ## Obsolete — what that means for sourcing Schneider Electric lists this gearbox as obsolete. No direct successor order code is published by the manufacturer. Available through independent surplus channels — quantities are lot-specific and confirmed at RFQ. The 160 mm frame size and 25:1 ratio are common in the Schneider GBX family, so a functional match from a different ratio or frame is possible but requires a mechanical re-check of the mounting interface and output shaft dimensions. A board-level or coupling-level re-design is needed if a direct drop-in is not found in surplus stock.","metaTitle":"Schneider Electric GBX1600250551F Planetary Gearbox, 25:1","metaDescription":"Schneider Electric GBX1600250551F planetary gearbox, 160 mm diameter, 25:1 reduction, 700 N.m continuous torque.
