The part is available through independent surplus and broker channels — quantities are lot-specific and confirmed at RFQ. No pin-compatible direct replacement exists from Schneider; a functional replacement would require a different frame size or ratio, meaning a mechanical rework of the mounting interface. ## Torque and duty cycle — what the ratings mean The GBX1200091402F is a planetary gearbox with straight teeth, 120 mm external diameter, and a 9:1 reduction ratio. Continuous output torque is 210 N.m at 100 rpm and 30 °C ambient; maximum output torque reaches 336 N.m under the same conditions. The 94% efficiency means 6% of input power is lost as heat — relevant for thermal budgeting in the driven system, especially at sustained full load. Service life is rated at 30,000 hours at 100 rpm and 30 °C, and the gearbox is lubricated for life — no maintenance oil changes, which simplifies installation in sealed or hard-to-access locations. Maximum torsional backlash is 12 arc.min, with torsional rigidity of 13 N.m/arcmin. For positioning applications, the 12 arc.min backlash at the output translates to roughly 1.3 arc.min at the input after the 9:1 reduction — acceptable for general indexing but not for precision servo-grade positioning where sub-arcmin backlash is required. Maximum axial force (Fa) is 2100 N at 100 rpm for the 30,000-hour life, or 2800 N for a 10,000-hour life. Maximum radial force (Fr) is 1500 N at 100 rpm for the 30,000-hour life, or 2000 N for the 10,000-hour life. These force limits apply at mid-distance from the output shaft — overhung loads beyond this point reduce the allowable force proportionally.","metaTitle":"Schneider Electric GBX1200091402F Planetary Gearbox, 9:1","metaDescription":"Schneider Electric GBX1200091402F planetary gearbox, 9:1 reduction, 210 N.m continuous torque, 94% efficiency.
