It delivers 230 N.m continuous torque at 100 rpm and 30 °C, with a peak of 368 N.m under the same conditions. That 94% efficiency figure means you're not losing much input power to heat — important when the motor upstream is already sized tight. The torsional backlash is rated at 12 arc-min maximum, and torsional rigidity is 13 N.m/arcmin. For positioning applications where the load reverses, that backlash figure tells you how much angular play to expect before the output shaft picks up the load. ## Lifecycle reality — obsolete, sourced through surplus Schneider Electric lists this gearbox as obsolete. That means the only channel to source it is independent surplus and broker inventory — quantities are lot-specific and confirmed at RFQ, not stocked on a shelf. The service life is rated at 30,000 hours at 100 rpm and 30 °C, and it's lubricated for life — no maintenance schedule for grease changes. If your application is already running this gearbox, the 30,000-hour clock is the planning horizon for a replacement. ## Mounting and environmental fit The housing is black anodized aluminium, 120 mm external diameter. Shaft material is C45 steel. The shaft output carries an IP54 rating — that's dust-protected and splash-resistant at the seal, but not submersible. Ambient operating range is -25 to 90 °C, which covers most indoor industrial environments. Maximum axial force on the output shaft is 2100 N at 100 rpm for the full 30,000-hour life, or 2800 N if you accept a shorter 10,000-hour service interval. Radial force limits are 1500 N and 2000 N respectively, applied at mid-distance on the output shaft. These are the limits that govern bearing life — exceeding them shortens the service hours proportionally.","metaTitle":"Schneider Electric GBX1200251402F planetary gearbox, 25:1","metaDescription":"Schneider Electric GBX1200251402F planetary gearbox, 25:1 ratio, 230 N.m continuous torque, 94% efficiency.
