It delivers 260 N.m continuous output torque at 100 rpm and 30 °C, with a maximum of 416 N.m under the same conditions. Efficiency is listed at 94 %, and the noise level at 65 dB at 1 m under no-load — figures that matter for energy-sensitive or sound-regulated production lines. ## Mechanical ratings and integration constraints The housing is black anodized aluminium, the shaft is C 45 steel. Shaft output sealing is IP54, so the gearbox is splash-resistant but not suited for pressurized washdown. Ambient operating range is -25 to 90 °C. Maximum axial force on the output shaft is 2100 N at 100 rpm for the 30000-hour service life, and 2800 N for a 10000-hour life. Maximum radial force (applied at mid-distance from the output shaft) is 1500 N for 30000 hours, 2000 N for 10000 hours. Torsional rigidity is 13 N.m/arcmin, and maximum torsional backlash is 12 arc.min. The gearbox is lubricated for life — no maintenance oil changes. Service life is rated at 30000 hours at 100 rpm and 30 °C. ## Lifecycle reality — obsolete, sourced to order Schneider Electric lists the GBX1200120553F as obsolete. No official successor is recorded. The part is available through independent surplus and broker channels — quantities are lot-specific and confirmed at RFQ. For a machine-tool rebuild or a line-down replacement, the key fit parameters to match are the 120 mm housing diameter, the 12:1 ratio, the 260 N.m continuous torque, and the C 45 shaft material. No pin-compatible drop-in from the same family is documented.","metaTitle":"GBX1200120553F Schneider Electric planetary gearbox, 12:1","metaDescription":"Obsolete Schneider Electric GBX1200120553F planetary gearbox, 12:1 ratio, 260 N.m continuous torque, 94% efficiency.
