Torque and load ratings that define the fit
The GBX1200251404F is a 120 mm-diameter planetary gearbox with a 25:1 reduction ratio, straight teeth, and a maximum torsional backlash of 12 arc.min — this backlash figure governs positioning repeatability in indexing or servo-driven axes where cumulative error stacks across multiple stages. Continuous output torque is 230 N.m at 100 rpm and 30 °C ambient; the maximum allowable torque reaches 368 N.m under the same conditions — the continuous figure is the one to size against for duty cycles above 60 % runtime, while the maximum covers intermittent overloads during acceleration or reversing. Service life is rated at 30,000 hours at 100 rpm and 30 °C, with the gearbox lubricated for life — no field regreasing interval, so the 30,000-hour mark is the replacement trigger in a scheduled-maintenance plan.
Sourcing reality — obsolete, quoted to order
Available through independent distribution channels; quantities and pricing are confirmed at RFQ against the BOM line. No pin-compatible drop-in replacement exists from Schneider — any substitution requires a re-evaluation of the mounting interface and torque envelope.
Mechanical integration and environmental limits
Maximum axial force (Fa) is 2100 N at 100 rpm for the 30,000-hour life target, rising to 2800 N for a 10,000-hour duty; maximum radial force (Fr) is 1500 N and 2000 N respectively, applied at mid-distance on the output shaft — these limits set the allowable overhung load from a belt, chain, or direct-coupled pulley.
