Continuous output torque is 230 N.m at 100 rpm and 30 °C; peak (maximum output torque) is 368 N.m under the same conditions. The 94 % efficiency figure means the input power required to hit that continuous torque is about 6 % higher than the output shaft power — factor that into your motor sizing. Rated service life is 30,000 hours at 100 rpm and 30 °C, lubricated for life — no oil-change interval, but the IP54 shaft output seal means it's not washdown-rated. The housing is black anodized aluminium; the shaft is C45 steel. ## Obsolete — sourcing through independent channels Schneider Electric lists the GBX1200250552F as obsolete. The part is available through independent surplus and broker channels; quantities are lot-specific and confirmed at RFQ. Before committing a BOM line, verify the axial and radial load ratings against your application: maximum axial force Fa is 2100 N for a 30,000-hour life at 100 rpm and 30 °C (2800 N for a 10,000-hour life); maximum radial force Fr is 1500 N for 30,000 hours (2000 N for 10,000 hours), both measured at mid-distance from the output shaft. Noise level at 1 m under no-load is 65 dB — a useful data point if the gearbox sits near a work cell with noise exposure limits.","metaTitle":"Schneider Electric GBX1200250552F planetary gearbox, 25:1","metaDescription":"Schneider Electric GBX1200250552F planetary gearbox, 120 mm, 25:1 ratio, 230 N.m continuous torque, 94% efficiency.
