Planetary gearbox, 16:1 reduction, 260 N.m continuous
The GBX1200161401F is a Schneider Electric planetary gearbox with a 16:1 reduction ratio and a continuous output torque rating of 260 N.m at 100 rpm and 30 °C. The straight-tooth design delivers 94 % efficiency, meaning roughly 6 % of input power is lost as heat through the gear train — a figure that holds steady across the rated speed range.
Torque capacity and service life at rated speed
Maximum output torque reaches 416 N.m (3681.9 lbf.in) at 100 rpm and 30 °C, while the continuous rating of 260 N.m defines the thermal steady-state limit for sustained duty. Service life is specified at 30,000 hours under these conditions — a figure that drops if the gearbox is run at higher ambient temperatures or above the continuous torque threshold. The gearbox is lubricated for life, so no field maintenance is required for the oil bath. The shaft output seal carries an IP54 rating, meaning it is protected against dust ingress and splashing water — suitable for environments where the gearbox is not directly hosed down.
Sourcing this obsolete gearbox — lifecycle and supply
Schneider Electric lists the GBX1200161401F as obsolete. The part is available through independent distribution channels; quantities are confirmed at RFQ, and pricing is quoted against the specific BOM line.
Mechanical interface and load limits
The output shaft is made of C45 steel, a medium-carbon grade that handles the rated radial and axial loads without deformation. Maximum radial force (Fr) is 1500 N at 100 rpm for the 30,000-hour life target, and maximum axial force (Fa) is 2100 N under the same conditions. Both figures are specified with the force applied at mid-distance from the output shaft — off-center loading reduces the allowable force proportionally. Torsional rigidity is 13 N.m/arcmin, meaning the gearbox twists 1 arcminute for every 13 N.m of applied torque. Maximum torsional backlash is 12 arcminutes — this is the angular play between input and output when the direction reverses. For positioning applications requiring less than 12 arcmin repeatability, a lower-backlash gearbox would be needed. Ambient temperature range for operation is -25 to 90 °C, covering most indoor industrial environments. The lubricant is factory-filled and sealed for life, so no viscosity adjustments are needed across this range.
