Maximum output torque reaches 1120 N.m (9912.8 lbf.in) under the same conditions, giving a 60 % overload margin above the continuous rating for peak loads. Efficiency is listed at 94 %, meaning roughly 6 % of input power is lost as heat through the straight-tooth planetary stages — a solid figure for a 25:1 reduction in this diameter class. ## Backlash, rigidity, and service life at 100 rpm Maximum torsional backlash is 10 arc.min — this is a standard-precision planetary stage, not a zero-backlash unit, so it suits positioning axes where the load holds position against the gear train stiffness rather than requiring reversal accuracy. Torsional rigidity is 41 N.m/arcmin, which means the output shaft twists 1 arc-minute for every 41 N.m of applied torque — a useful figure for estimating windup under load in a servo or stepper-driven indexing application. Rated service life is 30,000 hours at 100 rpm and 30 °C, with the gearbox lubricated for life — no oil changes or regreasing intervals to schedule in the maintenance plan. ## Shaft loading limits and environmental sealing Maximum axial force (Fa) on the output shaft is 6000 N for the full 30,000-hour life at 100 rpm, or 8000 N if you accept a shorter 10,000-hour service window — the trade-off is explicit in the rating table. Maximum radial force (Fr) is 4200 N at mid-span on the output shaft for 30,000 hours, rising to 6000 N for 10,000 hours — overhung loads from pulleys or sprockets must stay within these limits to avoid bearing fatigue. The shaft output carries an IP54 ingress rating, meaning the output seal resists dust and splashing water — adequate for most indoor machine environments but not washdown or outdoor exposure. ## Obsolete — sourcing through independent channels Available through independent surplus and broker channels — quantities are lot-specific and confirmed at RFQ. No pin-compatible or dimensionally identical replacement is published by Schneider for this frame size and ratio.","metaTitle":"Schneider Electric GBX1600250553F Planetary Gearbox, 25:1","metaDescription":"Schneider Electric GBX1600250553F planetary gearbox, 160 mm diameter, 25:1 ratio, 700 N.m continuous torque.
